Examples

State Management:

final count = 0.obs;

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Center(
      child: Column(
        children: [
          Text("Count: $count"),
          ElevatedButton(
            onPressed: () => count++,
            child: Text("Increment"),
          ),
        ],
      ),
    ),
  );
}

Routing:

import 'package:get/get.dart';

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          onPressed: () => Get.to(DetailsPage()),
          child: Text("Go to Details"),
        ),
      ),
    );
  }
}

class DetailsPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Text("Details"),
      ),
    );
  }
}

Dependency Injection:

class MyController extends GetxController {
  final String name;

  MyController(this.name);
}

class MyPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final controller = Get.find();
    return Scaffold(
      body: Center(
        child: Text("Name: ${controller.name}"),
      ),
    );
  }
}

Conclusion

GetX is an indispensable tool for any Flutter developer seeking to simplify state management, routing, and dependency injection. Its ease of use, performance, and community support make it an excellent choice for building high-quality Flutter applications.
