This Coverup Tutorial will help you to Build the Real Android Native apps using Flutter. Like this, I'm Going to cover this with the blogger because to have the regular update of the application and help you to build the real Native android apps from Scratch to a Complete Product & I will also help you in Production State for publishing and updating of the published apps.
Introduction:
In general, creating a mobile application is a very complex and challenging task. There are many frameworks available, which provide excellent features to develop mobile applications. For developing mobile apps, Android provides a native framework based on Java and Kotlin language, while iOS provides a framework based on Objective-C/Swift language. Thus, we need two different languages and frameworks to develop applications for both OS. Today, to overcome form this complexity, there are several frameworks have introduced that support both OS along with desktop apps. These types of frameworks are known as cross-platform development tools.

The cross-platform development framework has the ability to write one code and can deploy on various platforms (Android, iOS, and Desktop). It saves a lot of time and development efforts of developers. There are several tools available for cross-platform development, including web-based tools, such as Ionic from Drifty Co. in 2013, Phonegap from Adobe, Xamarin from Microsoft, and React Native form Facebook. Each of these frameworks has varying degrees of success in the mobile industry. In recent, a new framework has introduced in the cross-platform development family named Flutter developed from Google.
Flutter Tutorial PART-1: Building Real Native Apps.


Flutter is a UI toolkit for creating fast, beautiful, natively compiled applications for mobile, web, and desktop with one programing language and single codebase. It is free and open-source. It was initially developed from Google and now manages by an ECMA standard. Flutter apps use Dart programming language for creating an app. The dart programming shares several same features as other programming languages, such as Kotlin and Swift, and can be trans-compiled into JavaScript code.

Flutter is mainly optimized for 2D mobile apps that can run on both Android and iOS platforms. We can also use it to build full-featured apps, including camera, storage, geolocation, network, third-party SDKs, and more.

What is flutter?
        Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web,         and desktop from a single codebase.

Why Flutter? 
Flutter is different from other frameworks because it neither uses WebView nor the OEM widgets that shipped with the device. Instead, it uses its own high-performance rendering engine to draw widgets. It also implements most of its systems such as animation, gesture, and widgets in Dart programing language that allows developers to read, change, replace, or remove things easily. It gives excellent control to the developers over the system.
    Advantages:
  • Fast Development
           Flutter's hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times without losing state on emulators, simulators, and hardware.     
  • Expressive Beautiful UIs
        Delight your users with Flutter's built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness.
  • Native Performance
        Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons, and fonts to provide full native performance on both iOS and Android.

Here the Tutorial will be started, check down the below requirements that fulfill the System configuration that will help you to follow the project without any Interrupt, so if you have any doubts feel free to post it down on the comments,
Flutter Tutorial PART-1: INTRODUCTION: Building Real Native Apps.

System Requirements:

To install and run Flutter, your development environment must meet these minimum requirements:

  • Operating Systems: Windows 7 SP1 or later (64-bit)
  • Disk Space: 1.32 GB (does not include disk space for IDE/tools).
  • Tools: Flutter depends on these tools being available in your environment.
  • Windows PowerShell 5.0 or newer (this is pre-installed with Windows 10)
  • Git for Windows 2.x, with the Use Git from the Windows Command Prompt option.

If Git for Windows is already installed, make sure you can run git commands from the command prompt or PowerShell.

 so check out this system configurations before starting. If you have any more doubts refer to the official Site for the flutter Installation from here. because I'm not going to bore for saying about installation,

Here in the Tutorial, I'm going to use Visual Studio Code Editor, Android Studio, and Related SDK.
if you have finished with this installation and the meeting requirements Jump to Part-2 of this tutorial from here.
