Getting Started with GetX

Setting Up My Project

To begin, Let's create a new Flutter project using the command flutter create getxdemo. Once generated, open the project in your preferred code editor.

Next, let's optimize our project structure by removing unnecessary folders like Linux, windows, etc. (if you're only targeting Android and iOS platforms).

Now, let's organize our project structure using the MVC (Model-View-Controller) pattern:

/controllers # GetX controllers /models # Project models /services # Project services /shared # Helpers, app theme, and utils /views # GetX views and layouts

Integrating GetX

With the project structure set up, the next step is to integrate GetX into the Flutter project. Run flutter pub add get to install the latest GetX package, which will provide us with powerful state management and routing capabilities.

Configuring the Main File

Finally, let's configure the main.dart file to leverage GetX. Replace the boilerplate code with the following:

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:getxdemo/views/screens/splash_screen.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      title: 'GetX Demo',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const SplashScreen(),
    );
  }
}        

By replacing MaterialApp with GetMaterialApp, we're now set up to take advantage of GetX's features seamlessly.
