Configuring the Environment for Development

Setting up your development environment is a must before you can begin creating Flutter applications. To get started, take these actions:

Get the Flutter SDK from the official Flutter website (https://flutter.dev) and install it. Select the version that is compatible with your current operating system.
On your PC, extract the SDK that you downloaded.
Update the PATH variable on your PC with the Flutter SDK. This will let you use any directory in the command line to execute Flutter commands.
Launch the command flutter doctor in a fresh terminal or command prompt window to confirm the installation. This tool looks for any dependencies that Flutter needs on your system and gives you instructions on how to fix any problems.
Install a code editor, such as Android Studio (https://developer.android.com/studio) or Visual Studio Code (https://code.visualstudio.com/).
In the coding editor of your choice, install the Flutter and Dart extensions. The capabilities and tools offered by these extensions are beneficial for Flutter development.

Your development environment for creating Flutter apps has been successfully set up.

Steps to Build An App In Flutter Cross-Platform Framework

Establishing a New Flutter Project:

To begin going, do the following actions to establish a new Flutter project:

Using Flutter CLI:

To create a project using Flutter CLI, open a terminal or command line and browse to the required directory.

To start a new Flutter project with the name my_app, type flutter create my_app.

Using IDE:

You may start a new Flutter project using the IDE’s interface if you’d rather use an Integrated Development Environment (IDE), such as Visual Studio Code (VS Code) or Android Studio.

Choose “New Flutter Project” or “Create New Flutter Project” by pressing Ctrl/Cmd + Shift + P. Give your project the name my_app.

Knowing the Basic Structure

After creating your Flutter project, it’s critical to become acquainted with its fundamental structure. The following are the main files and folders you’ll find:

lib Directory:

The primary Dart code for your application is located in this directory. The main.dart file serves as your app’s entry point and is where you define its UI and behavior.

assets Directory:

Put any static assets—such as JSON files, photos, or typefaces—into this directory. Later on, you may use these assets as references in your code.

pubspec.yaml File:

In this file, you list all of the dependencies for your application, including any external packages you choose to utilize. Here, you can also set up additional project options and provide asset locations.

Build A Simple Looking Flutter App With UI Components

Let’s start building the user interface of our app using basic Flutter UI components:

import 'package:flutter/material.dart';

void main() {

 runApp(MyApp());

}

class MyApp extends StatelessWidget {

 @override

 Widget build(BuildContext context) {

   return MaterialApp(

     title: 'My App',

     home: Scaffold(

       appBar: AppBar(

         title: Text('My App'),

       ),

       body: Center(

         child: Text('Welcome to etwinworkshop!'),

       ),

     ),

   );

 }

}

import 'package:flutter/material.dart';

void main() {

runApp(MyApp());

}

class MyApp extends StatelessWidget {

@override

Widget build(BuildContext context) {

return MaterialApp(

title: 'My App',

home: Scaffold(

appBar: AppBar(

title: Text('My App'),

body: Center(

child: Text('Welcome to etwinworkshop!'),

);

}

A MyApp class that extends the StatelessWidget class is defined in the code above. The MaterialApp widget that is returned by the build function serves as our app’s root widget.

The home screen of our app is defined as a scaffold widget within MaterialApp. For the app bar, the Scaffold has an AppBar widget; for the app body, it has a Center widget with a Text widget.

Using Flutter’s Inbuilt Navigation System to Implement Screen Navigation

Let’s now use Flutter’s built-in navigation system to implement screen navigation:

import 'package:flutter/material.dart';

void main() {

 runApp(MyApp());

}

class MyApp extends StatelessWidget {

 @override

 Widget build(BuildContext context) {

   return MaterialApp(

     title: 'My App',

     initialRoute: '/',

     routes: {

       '/': (context) => HomeScreen(),

       '/second': (context) => SecondScreen(),

     },

   );

 }

}

class HomeScreen extends StatelessWidget {

 @override

 Widget build(BuildContext context) {

   return Scaffold(

     appBar: AppBar(

       title: Text('Home'),

     ),

     body: Center(

       child: ElevatedButton(

         onPressed: () {

           Navigator.pushNamed(context, '/second');

         },

         child: Text('Go to Second Screen'),

       ),

     ),

   );

 }

}

class SecondScreen extends StatelessWidget {

 @override

 Widget build(BuildContext context) {

   return Scaffold(

     appBar: AppBar(

       title: Text('Second Screen'),

     ),

     body: Center(

       child: Text('This is the second screen!'),

     ),

   );

 }

}

import 'package:flutter/material.dart';

void main() {

runApp(MyApp());

}

class MyApp extends StatelessWidget {

@override

Widget build(BuildContext context) {

return MaterialApp(

title: 'My App',

initialRoute: '/',

routes: {

'/': (context) => HomeScreen(),

'/second': (context) => SecondScreen(),

);

}

class HomeScreen extends StatelessWidget {

@override

Widget build(BuildContext context) {

return Scaffold(

appBar: AppBar(

title: Text('Home'),

body: Center(

child: ElevatedButton(

onPressed: () {

Navigator.pushNamed(context, '/second');

child: Text('Go to Second Screen'),

);

}

class SecondScreen extends StatelessWidget {

@override

Widget build(BuildContext context) {

return Scaffold(

appBar: AppBar(

title: Text('Second Screen'),

body: Center(

child: Text('This is the second screen!'),

);

}

In the above code, we define two additional classes: HomeScreen and SecondScreen. The initialRoute property of MaterialApp is set to “/”, which represents the home screen.

The routes property maps named routes to corresponding screen widgets. In HomeScreen, we use the Navigator.pushNamed method to navigate to the second route when the button is pressed.

However, these steps can’t be implemented by yourself unless you are a pro coder running a business, we ask you to consult an experienced Flutter app development company.
