Flutter is a mobile application SDK for building high performance, high-fidelity for Android and iOS. Flutter is a new framework for building of native Android and iOS. Flutter is Google’s mobile app SDK for crafting high-quality native interfaces on iOS and Android in record time. Flutter works with existing code, is used by Android and iOS developers and organizations globally. 

flutter Android & iOS

Advantages of Flutter

    Highly Productive

  • Using a single codebase can be developed for Android and iOS application.
  • Developing language is Dart and it is very easy to understand.
  • Less code requires for single OS using modern, expensive language and a declaration approach.
  • App reload runs executing very fast while changing the code using hot reload

    Create beautiful and highly-customized user experiences

  • Create a rich set of Material design and Cupertino widgets build using Flutter’s own framework using the stateful widget and stateless widget.
  • No limitation of OEM widget sets 

Fast Development

  • Hot reload feature will be run your application in milliseconds. You can use a rich and fully customizable widget in a minute.

    Expressive and Flexible UI

  • Flutter is providing expressive UI supports using a different kind of inbuilt widget. It’s very fast to load and support in both Android and iOS devices. It will look like natural feeling in android and ios application. There is no available graphical UI representor to create UI, you have to create UI using a code and it is very flexible.

    Native Performance

  • Flutter is using the widget for UI design and supports in Android and iOS devices. It is supporting of native components and API. Flutter is reusing your existing java, swift, and objective C, access native features, and SDK on Android and iOS

Flutter Development

Flutter is using Dart language to develop a mobile application. Dart is a very simple language and easy to understand. Dart is a basic client based optimization language with rich and powerful framework along with flexible tooling. It is well suited to reactive programming and support of asynchronous programming through language features and powerful APIs. You can start coding in Dart in no time and Dart has been introduced new version Dart 2 with many new features. For more about Dart can be available on the website: [https://www.dartlang.org/

Flutter Architecture 

Flutter Architecture

Flutter is based on the C++ engine that comprises Skia. The framework is based on the engine and comprises widgets, rendersting, animation, etc. The framework is organized into a series of layers and each layer building upon the previous layer. The goal of the design is to help you can develop an application for Android and iOS in less code. 


The beginning of Flutter Development

  1. Setup and Configure Editor
  • Flutter SDK:
    Install the Flutter SDK, open and download SDK from this link [https://flutter.io/get-started/install/]
  • Once download the SDK, Extract the file in the specific location:
    $ cd ~/<Your Location>

$ tar xf ~/Downloads/flutter_linux_v0.5.1-beta.tar.xz

  • Set the Flutter path:
    $ export PATH=`pwd`/flutter/bin:$PATH
  • You are now ready for run Flutter commands! 
  • Run the flutter doctor for check if any dependencies are missing and you need to install.                                              $ flutter doctor

         Android Setup

  • Download and Install Android studio from this link [https://developer.android.com/studio/]
    Setup Android studio and latest SDK as well.
  • Install PlugIn
    Install Flutter plugin for developing, running, hot reload, etc
    Install Dart plugin for code analysis, validation, completions, etc.

    Follow this steps to install a plugin in Android studio

  • Start Android Studio
  • Open plugins preferences (Preferences>Plugins on macOS, File>Settings>Plugins on Windows & Linux).
  • Select Browse repositories…, search flutter and install
  • Click Yes when prompted to install the Dart plugin.
  • Click Restart when prompted

2. Create a new Application

  • Select New Flutter Project
  • Select Flutter application as the project type and click Next
  • Enter your project name (E.g. myflutterapp) and click Next
  • Click to Finish

3. Run the application

  • Attach device with your system and it will appear in Toolbar section.
  • If you have not available device then create an emulator using AVD Manager. (Tools> Android> AVD Manager)
  • Click the Run icon in the toolbar and application will be run in your device.
  • If everything is work, then it will show the application screen in your device and emulator.

This is the code sample:

import ‘package:flutter/material.dart’;

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {

// This widget is the root of your application.


Widget build(BuildContext context) {

  return new MaterialApp(

    home: new MyHomePage(),




class MyHomePage extends StatefulWidget {


_MyHomePageState createState() => new _MyHomePageState();


class _MyHomePageState extends State<MyHomePage> {


Widget build(BuildContext context) {

  return new Scaffold(

    appBar: new AppBar(

      title: new Text(‘Flutter’),


    body: new Center(

    child: new Text(

   ‘Welcome to LetsNurture’,






So, this is the basic flutter application so you can get an idea about to setup flutter and how you can use the flutter IDE tool. For more explore about Flutter use this website link [https://flutter.io/get-started/codelab].

Google has been using flutter in many internal projects before open into the public. Flutter development primarily archived speed using stateful hot reload, reactive development and programming, widget composition and UI as code. Flutter offers the same team the capability to develop an application for both Android and iOS, with higher speed and better performance, and reducing the manpower.
