How to use flutter software for a beginner and review

Introduction to flutter software

Flutter software is not a programming language. It is an open-source mobile application development framework created by Google. As I researched how to use flutter software for a beginner since we also need to move ahead with this growing word  It is used to develop applications for Android and iOS, as well as being the primary method of creating applications for Google Fuchsia. Since with the launch of Fuchsia OS, this software will be in trend in the future. The language used in a flutter software for programming is Dart programming language. Google flutter platform has recently released but its popularity is in height in this short period. Used by popular companies like Alibaba, App Tree.

How to use flutter software for beginner

For a beginner, flutter software will be a totally new platform because it is new in the market if you master in this with a great opportunity in the future if it comes on trend.

First, you need to install the flutter software in your system. which must be available in Google play store or outsource website like flutter download

flutter Beta 3 version

Second, you should learn the dart programming language in order to get into the flutter app. Because it uses Dart programming language in order to work on it. So get lessons from youtube or if you need a guidance teaching then you should try the online tutorial here we conduct the full step by step course for the beginners for the hungry talented people like you.

Third, if you have learned the language then you should learn its widget and the predefined functions of the app. A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms. Graphical control elements (GUI “widgets”) are examples of reusable modular components that are used together to build a more complex application, allowing programmers to build user interfaces by combining simple, smaller parts.


Advantages of using flutter software

  • Extremely Fast App Development: With features like Hot-reload, code changes in Flutter software are reflected as soon as the alterations are made. The Hot-reload usually doesn’t take more than milliseconds, which helps developers to maintain high speeds and dynamicity for mobile app development. Flutter widgets assist in the creation of native interfaces within a few minutes.
  • Reactive Framework: With the reactive framework, the developers do not need to update UI contents manual and UI changes will be visible automatically.
  • Good for MVP: Flutter is good for developing MVP (Minimum Viable Product) apps due to its speedy development process and cross-platform nature. Many modern undertakings and SMEs are thus employing flutter to increase development speeds and get the maximum outputs at lower costs.
  • Access of Native Features: It is extremely simple to set-up Flutter. Developers can easily have access to native features of low-level machines when initiated. Since it is cross-platform in nature, codes can be reused in any application platform.
  • Faster Running of Applications: Flutter software provides smooth and seamless scrolling experiences while in use, without much hangs or cuts.
  • Reduced Efforts of Testing: Since Flutter apps are cross-platform, the testers do not always require to run the same set of tests on different platforms, such as iOS and Android, for the same app. Cross-platform application development enables applications to run on multiple platforms by writing the programming code only once (follows the WORA concept). This saves the time of the testing team. 

Disadvantages of flutter software

it is noted for many of its interesting features but still has the following drawbacks.

  • Web browsers do not support Flutter software : Flutter apps are supported by Android and iOS, but not by web browsers.
  • Limited Libraries: The libraries to be accessed by the mobile application developers is very limited in Flutter. Functionalities need to be developed by application developers themselves.
  • Needs Continuous Support: Since Flutter is comparatively new, it needs continuous integration support through maintenance of scripts, as CI platforms like Jenkins do not support Flutter on a large scale.

Conclusion

Flutter is a great cross-platform solution and is growing day by day in popularity. Developers are adopting flutter software for mobile development and startups are also looking to hire flutter developers for building their mobile application. It’s definitely worth looking into if you are considering to enter cross-platform development space.

If you can afford to have a native app for iOS and Android, you might wanna refrain away from going cross-platform to flutter software. It still has a long way to go in order to match the quality of a native app.

Flutter : Build beautiful native apps in record time

Flutter (software)

Flutter is a new mobile development SDK brought to you by Google to help you build fast, beautiful, and cross-platform mobile applications. It uses a new language called Dart. If you are worried about having to learn a whole new programming language to build Flutter Apps, don’t be! Dart is majorly influenced  by languages like JavaScript and Java. This helps reducing the learning curve significantly.

Basic Introduction

On May 2017 Alpha Version of Flutter was released and who knows in coming 1 year,Google will create the Beta-3 version of its own newly built SDK.Now, for those who are not much known about this SDK thing i.e who are not much aware about Mobile App development thing, SDK is defined as Software Development Kit, which just means that is a set of tools that can be used to develop Software applications targeting specific platform.

Now the platform above mentioned means that on which Environment it is working, and the most important feature  of this flutter thing is that it supports Both iOS and Android.

Lets Put Some Spotlight On this!!

Flutter includes a modern react style framework, a ready made widgets and development tools. These components will enable you to design, build and debug apps.

Everything in Flutter Is a Widget: Widgets are just building blocks for defining user interfaces     (Everything Displaying On Screen).

UI design in Flutter involves assembling and/or creating various widgets. A widget in Flutter represents the description of part of the user interface; all graphics, including text, shapes, and animations are created using widgets. More complex widgets can be created by combining many simpler ones.

If anyone who is known about mobile App development will get this point that, from views to separate views as well   as the layouts controllers are all defined under widgets in Flutter.

Simply Widget can be :

  • a Structural element  (like a button)
  • a Stylist Element (like a font or color)
  • an aspect of layout (like padding, margin)

  Design-specific widgets

The Flutter framework contains two sets of widgets which conform to specific design languages. Material Design  widgets implement Google’s design language of the same name, and Cupertino widgets imitate Apple’s iOS design.

  Plus Points Of Flutter  
  1. Fast Development : There is a hot reload feature in Flutter, which enables developers to paint their app to life. It enables developers to quickly experiment,build user interfaces, add features and solves bugs faster. Experience sub second reload times, without losing state on emulators, for bot iOS and Android.
  2. Efficient : Flutter enables developers to make changes in the code during compilation time, also after fixing crashes app will be start to debugging from where it left off.
  3. Expressive and  Flexible UI : Flutter has in-built beautiful material design (Android Guidelines) and Cupertino (iOS Flavour) widgets , with platform awareness i.e the natural interfaces of iOS and Android will be differentiated  though they are made on same thing (Flutter).
  4. Native Performance : One of the most prominent feature of using flutter is that the native feel of an Android App and an iOS App will be there, like Scrolling, navigation Icons,fonts etc.

Hopefully You Guys like this simple, short and probably most convenient form of information about Flutter . Soon    Will upload more stuff related to flutter

Flutter Listview Example

Flutter Listview Example

Implementation of sample app with Fultter

This blog basically determines how to implement the basic mobile design pattern with Flutter.  This sample is short i.e will display just an Dart file but with the complete applications. The application i am going to show is the expansionist.

This application will display the hierarchical data with Expansion List. By Tapping a list i.e parent this will expand the view to its children. When a list is expanded its children are further biased so as to reflect what’s visible. This is a scrollable list that is created with the List View.builder().

Flutter Code for the application is illustrated below:

import ‘package:flutter/material.dart’;

class ExpansionTileSample extends StatelessWidget {

@override

Widget build(BuildContext context) {

return MaterialApp(

home: Scaffold(

appBar: AppBar(

title: const Text(‘ExpansionTile’),

),

body: ListView.builder(

itemBuilder: (BuildContext context, int index) =>

EntryItem(data[index]),

itemCount: data.length,

),

),

);

}

}

class Entry {

Entry(this.title, [this.children = const <Entry>[]]);

final String title;

final List<Entry> children;

}

final List<Entry> data = <Entry>[

Entry(

‘Chapter A’,

<Entry>[

Entry(

‘Section A0’,

<Entry>[

Entry(‘Item A0.1’),

Entry(‘Item A0.2’),

Entry(‘Item A0.3’),

],

),

Entry(‘Section A1’),

Entry(‘Section A2’),

],

),

Entry(

‘Chapter B’,

<Entry>[

Entry(‘Section B0’),

Entry(‘Section B1’),

],

),

Entry(

‘Chapter C’,

<Entry>[

Entry(‘Section C0’),

Entry(‘Section C1’),

Entry(

‘Section C2’,

<Entry>[

Entry(‘Item C2.0’),

Entry(‘Item C2.1’),

Entry(‘Item C2.2’),

Entry(‘Item C2.3’),

],

),

],

),

];

class EntryItem extends StatelessWidget {

const EntryItem(this.entry);

final Entry entry;

Widget _buildTiles(Entry root) {

if (root.children.isEmpty) return ListTile(title: Text(root.title));

return ExpansionTile(

key: PageStorageKey<Entry>(root),

title: Text(root.title),

children: root.children.map(_buildTiles).toList(),

);

}

@override

Widget build(BuildContext context) {

return _buildTiles(entry);

}

}

void main() {

runApp(ExpansionTileSample());

}

Adding Interactivity to Your Flutter App

Stateful and stateless widgets :

Stateless Widget- A stateless widget is the one which directly has no internal state to manage.Some of the examples of the Stateless widgets are Icon, IconButton and Text.

Stateful Widgets: A stateful widget is basically a dynamic widget. In this the user can get in touch i.e interact with the stateful widget for example by typing into a form, or moving a slider etc . Some of the major example of the Stateful Widgets are Checkbox,Radio,Slider,InkWell,Form and TextField.

Creation of the stateful widget:

Now for the creation of the stateful widget you will have to create a custom stateful widget. Where you replace two stateless widgets i.e the solid red star and the numeric count next to it with a one single custom stateful widget that will manage the row with the two children widgets i.e an IconButton and Text.

So there are 4 major steps for the creation of Stateful widget which will be discussed below:

Step 1: Choosing of the object which manages the widget’s state

There are basically many different ways to manage the state of the widget, but here we will talk about the the widget itself i.e FavoriteWidget, which will manage its own widget state. for example, toggling of the star is an isolated action that will not affect its parent widget or your rest of the UI, so the widget will handle its state internally.

Step 2 : Subclass StatefulWidget

The FavoriteWidget class will manages its own state, so it overrides the createState() to create the State object. Then the framework calls createState() when it wants to build the widget. In the following example, createState() creates an instance of _FavoriteWidgetState, which you will implement it later.

Example- class FavoriteWidget extends StatefulWidget {

@override

_FavoriteWidgetState createState() => _FavoriteWidgetState();

}

Step 3 : Subclass State

The custom State class is basically used to store the mutable information which includes the logic and internal state that can change the lifetime of the widget.

Step 4: Plug the stateful widget into the widget tree

Add your custom stateful widget to the widget tree in the app’s build method.

Manipulating position and size-
To perform more complex operation on the widgets like position, size and background, the following categories are defined .
• Setting absolute position – As we all know by default every child widget is positioned relative to their parent widget. But to specify an absolute position for any of the widget on x axis oy y axis you will have to positioned that widget and then nest in a stack widget.

Flutter

Example below is shown in both html/CSS and flutter:
html:

Lorem ipsum

.greybox {
background-color: #e0e0e0;
width: 320px;
height: 240px;
font: 900 24px Roboto;
position: relative;
}
.redbox {
background-color: #ef5350;
padding: 16px;
color: #ffffff;
position: absolute;
top: 24px;
left: 24px;
}
Flutter: var container = Container( // grey box
child: Stack(
children: [
Positioned( // red box
child: Container(
child: Text(
“Lorem ipsum”,
style: bold24Roboto,),
decoration: BoxDecoration(
color: Colors.red[400],),
padding: EdgeInsets.all(16.0),),
left: 24.0,
top: 24.0,
),],),
width: 320.0,
height: 240.0,
color: Colors.grey[300],);
• Rotating components- If you want to rotate your widget then you will have to nest it in a Transform widget. For that you will have to use the transform widgt’s alignment and ofcourse its origin properties to define the transform origin in the relative and absolute words respectively. In a 2D rotation the widget can be rotated on the Z axis using radians i.e degrees * 3.14/180.
Example below is shown for rotating components in both html/CSS and flutter:
html:

Lorem ipsum

.greybox {
background-color: #e0e0e0; /* grey 300 */
width: 320px;
height: 240px;
font: 900 24px Roboto;
display: flex;
align-items: center;
justify-content: center;
}
.redbox {
background-color: #ef5350; /* red 400 */
padding: 16px;
color: #ffffff;
transform: rotate(15deg);
}
Flutter: var container = Container( // gray box
child: Center(
child: Transform(
child: Container( // red box
child: Text(
“Lorem ipsum”,
style: bold24Roboto,
textAlign: TextAlign.center,
),
decoration: BoxDecoration(
color: Colors.red[400],
),
padding: EdgeInsets.all(16.0),
),
alignment: Alignment.center,
transform: Matrix4.identity()
..rotateZ(15 * 3.1415927 / 180),
),
),
width: 320.0,
height: 240.0,
color: Colors.grey[300],
);

This blog is particularly for the users who are simply familiar with the HTML and CSS syntax for aligning components of an application’s UI. It basically maps HTML/CSS code to their Flutter/Dart code equivalents.

1) Layout operations – There are different following categories to perform the most common UI layout.

• Styling and aligning text- The different attributes of Styling are Font style, size and other text attributes that is handled by CSS with the different font and color properties are particular properties of a Textstyle child of a Text widget.

So now the comparison between the html and flutter is shown by considering the following example :

html: <div class=”greybox”>

Lorem ipsum

</div>

 

.greybox {

background-color: #e0e0e0;

width: 320px;

height: 240px;

font: 900 24px Georgia;

}

Flutter: var container = Container( // grey box

child: Text(

“Lorem ipsum”,

style: TextStyle(

fontSize: 24.0

fontWeight: FontWeight.w900,

fontFamily: “Georgia”,

),),

width: 320.0,

height: 240.0,

color: Colors.grey[300],

);

Setting background color – In Flutter, background of your UI is set using the a Container’s decoration property. Whereas in CSS, hex color is used equivalent to the

Material color palette.

Example is shown below for setting of the background color in html and flutter.

Html: <div class=”greybox”>

Lorem ipsum

</div>

.greybox {

background-color: #e0e0e0;

width: 320px;

height: 240px;

font: 900 24px Roboto;

}

Flutter:  var container = Container( // grey box

child: Text(

“Lorem ipsum”,

style: bold24Roboto,

),

width: 320.0,

height: 240.0,

color: Colors.grey[300],

);

 

Centering components: A Center widget is basically used to center its child both in a horizontally and vertically manner. Whereas in CSS to attain a similar effect, the parent widget uses either a flex or table-cell to display this behavior.

 Example: The flex behavior example is shown below:

Html: <div class=”greybox”>

Lorem ipsum

</div>

.greybox {

background-color: #e0e0e0; /* grey 300 */

width: 320px;

height: 240px;

font: 900 24px Roboto;

display: flex;

align-items: center;

justify-content: center;

}

Flutter: var container = Container( // grey box

child:  Center(

child:  Text(

“Lorem ipsum”,

style: bold24Roboto,

),

),

width: 320.0,

height: 240.0,

color: Colors.grey[300], );

 

 

 

 

 

 

 

 

  Glimpse of iOS developers on flutter Part 2

Glimpse of iOS developers on flutter Part 2

  • View Controllers – In iOS, a ViewController is something which represents a bit of UI i.e user interface, which is commonly mostly used for a screen. These are basically possessed together to frame difficult user interfaces, and to help you to map your application’s UI. Whereas in Flutter, this is basically done by the Widgets, UI screens in Flutter are basically represented by the Widgets since in flutter everything is a widget.

•  Gestures Detections and click listeners-

In iOS, an GestureRecognizer is attatched to a UIview to handle different click events. In Flutter, there are basically two ways to add touch listeners which are mentioned below:

  1. In the first case you will have to check if the widget is backing up event detection, then pass a function to it, and accordingly then handle the different events in the suitable function. Check on to the example mentioned below to get more clarity.

Example: @override

Widget build(BuildContext context) {

return new RaisedButton(

onPressed: () {

print(“click”);

},

child: new Text(“Button”),

);

}

  1. Second is the case in which the Widget does not support the detection of the events, so then you will have to go for the alternative i.e wrap the widget in a Gesture Detector and then pass a function accordingly to the onTap parameter. Check the example for the more clarity.

Example: class SampleApp extends StatelessWidget {

@override

Widget build(BuildContext context) {

return new Scaffold(

body: new Center(

child: new GestureDetector(

child: new FlutterLogo(

size: 200.0,),

onTap: () {print(“tap”);

},),),);

}

}

  • Databases and local storage– In iOS, collection of key-value pairs is stored using a property called list, also known as the User Defaults. Whereas in Flutter, you will have to access equivalent functionality using the Shared Preferences Plugins. This plugin is basically used to wrap the functionality of both the User Defaults and the Android equivalent, Shared Preferences.
  • NotificationsIn iOS, first you need to register your application on the developer portal to allow it push the various notifications. Whereas In Flutter, you can easily have the access this functionality using the firebase messaging

Glimpse of iOS developers on flutter

Glimpse of iOS developers on flutter

If you’re an iOS Developer and want to try something new i.e if you are looking forward to build mobile applications with Flutter then you are absolutely on the right path. While building apps with Flutter your iOS Proficiency is highly valuable because flutter absolutely gambles on the mobile operating system for infinite configurations.

 

So now lets a have look at the topics those are most relevant to any iOS developers needs to build applications using Flutter.

  • Views– UI in the Ios is mostly created using the view objects,which are then the instances of the UIView class which also can act as the container.

In Flutter unlike UIview, we have a widgets. Widgets do not map exactly to the Ios   UIview but to the much extent we can use this terms as a way we declare and construct UI. Flutter’s widgets are lightweight, in part due to their immutability.

 

  • Navigation- In iOS, to go along in between the UIview controllers, UINavigationController is used by the developers that accordingly manages the stack of view that auditors to display the same.

•     Asynchronicity of code – Dart is basically a language which has a single-threaded execution model, with a way to run Dart code on an another thread, an event loop, and also an asynchronous programming. Without you spawn an Isolate, your Dart code will always runs in the main UI thread and that is consumed by an event loop. Whereas in case of Flutter, its event loop is comparable to the iOS main loop which basically means that the Looper that is attached to the main thread.

  • Layouts- In iOS, to show the list either a UITableView or a UICollectionView is used by most of the developers. Whereas in Flutter, ListView is used by the developers for the implementation of the ListView. In iOS, these views have delegate methods for selecting the number of rows, the cell for each index, and also the size of the cells. Flutter also enables some extra features for the ListView is that Due to its inflexible widget pattern, you can pass a list of widgets to your ListView and you dont have to worry about anything Flutter takes care of making sure that scrolling is fast and smooth.

Some more different categories alike shall be discussed in the coming blogs and would be carried forward briefly so stay tuned.
