Hi ,In this Flutter tutorial we are going to learn how make first Flutter project import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatelessWidget {   @override   Widget build(BuildContext context) {     return MaterialApp(       title: 'Welcome to Flutter',       home: Scaffold(         appBar: AppBar(           title: Text('Welcome to Flutter'),         ),         body: Center(           child: Text('Hello World'),         ),       ),     );   } }

Get the  Flutter SDK Download the following installation bundle to get the latest stable release of the Flutter SDK:   flutter_windows_v1.12.13+hotfix.7-stable.zip For other release channels, and older builds, see the  SDK archive  page. Extract the zip file and place the contained  flutter  in the desired installation location for the Flutter SDK (for example,  C:\src\flutter ; do not install Flutter in a directory like  C:\Program Files\  that requires elevated privileges). Update  your path If you wish to run Flutter commands in the regular Windows console, take these steps to add Flutter to the  PATH  environment variable: From the Start search bar, enter ‘env’ and select  Edit environment variables for your account . Under  User variables  check if there is an entry called  Path : If the entry exists, append the full path to  flutter\bin  using  ;  as a separator from existing values. If the entry doe

In this chapter, let us discuss the architecture of the Flutter framework. Widgets The core concept of the Flutter framework is  In Flutter, Everything is a widget . Widgets are basically user interface components used to create the user interface of the application. In  Flutter , the application is itself a widget. The application is the top- level widget and its UI is build using one or more children (widgets), which again build using its children widgets. This  composability  feature helps us to create a user interface of any complexity. For example, the widget hierarchy of the hello world application (created in previous chapter) is as specified in the following diagram − Here the following points are worth notable − MyApp  is the user created widget and it is build using the Flutter native widget,  MaterialApp . MaterialApp  has a home property to specify the user interface of the home page, which is again a user created widget,  MyHomePage . MyHomePage  is b

Flutter is build with C, C++, Dart and Skia. And the most beautiful part is that all release code is compiled in native code (Android NDK, LLVM, AOT-compiled) without interpreter involved. If you are familiar with performance drawbacks of hybrid frameworks you can easy say that flutter compile fastest code very close to pure native performance. Flutter is different than most other options for building mobile apps because Flutter uses neither WebView nor the OEM widgets that shipped with the device. Instead, Flutter uses its own high-performance rendering engine to draw widgets. In addition, Flutter is different because it only has a thin layer of C/C++ code. Flutter implements most of its system (compositing, gestures, animation, framework, widgets, etc) in  Dart  (a modern, terse, object-oriented language) that developers can easily approach read, change, replace, or remove. This gives developers tremendous control over the system, as well as significantly lowers the bar to appr

Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for  mobile ,  web , and  desktop  from a single codebase. Fast Development Paint your app to life in milliseconds with Stateful Hot Reload. Use a rich set of fully-customizable widgets to build native interfaces in minutes. Expressive and Flexible UI Quickly ship features with a focus on native end-user experiences. Layered architecture allows for full customization, which results in incredibly fast rendering and expressive and flexible designs. Native Performance Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts, and your Flutter code is compiled to native ARM machine code using  Dart's native compilers . Thus Flutter gives you full native performance on both iOS and Android.
