Introduction:

Here we learn about the Use GetX in Flutter Apps. At baseprogrammer.com, we always try to simplify complex Flutter topics for developers. Flutter has evolved a lot, but state management, navigation, and dependency injection are still challenging for many beginners.

That’s where GetX shines. It’s lightweight, fast, and removes boilerplate. In 2025, developers still prefer GetX because:

  • It combines state management + routing + dependency injection in one package.
  • It reduces boilerplate compared to Provider, Redux, or Bloc.
  • It works seamlessly across mobile, web, and desktop apps.

In this updated guide, we’ll cover everything about use GetX in Flutter apps in 2025, with real examples from a Baseprogrammer Blog App project.

Let’s say we’re building a Blog App for baseprogrammer.com. We’ll use GetX for state management, navigation, and dependency injection.

1.State Management Example (Blog Controller)

controllers/blog_controller.dart

import 'package:get/get.dart';

class BlogController extends GetxController {
  var blogs = ["Welcome to Baseprogrammer.com"].obs;

  void addBlog(String blogTitle) {
    blogs.add(blogTitle);
  }
}

main.dart

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'controllers/blog_controller.dart';
import 'pages/home_page.dart';

void main() {
  // Injecting BlogController globally
  Get.put(BlogController());
  runApp(const MyApp());
}

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

  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      debugShowCheckedModeBanner: false,
      title: "Baseprogrammer Blog App",
      home: HomePage(),
    );
  }
}

pages/home_page.dart

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import '../controllers/blog_controller.dart';

class HomePage extends StatelessWidget {
final BlogController blogController = Get.find();

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Baseprogrammer Blogs")),
body: Obx(() => ListView.builder(
itemCount: blogController.blogs.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(blogController.blogs[index]),
);
},
)),
floatingActionButton: FloatingActionButton(
onPressed: () => blogController.addBlog("New Post at ${DateTime.now()}"),
child: Icon(Icons.add),
),
);
}
}

Now every time you tap the button, a new blog post appears instantly — thanks to GetX’s reactive Obx() widget.

2.Navigation Example (Pages in Baseprogrammer App)by Use GetX in Flutter

pages/about_page.dart

import 'package:flutter/material.dart';

class AboutPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text("About Baseprogrammer")),
      body: Center(child: Text("This is the About Page of Baseprogrammer.com")),
    );
  }
}

Inside HomePage:

ElevatedButton(
  onPressed: () => Get.to(() => AboutPage()),
  child: Text("Go to About Page"),
)

With Get.to(), you don’t need Navigator.of(context) — navigation is simpler.

Best Practices (2025)

  • Keep Logic in Controllers – Avoid mixing logic with UI.
  • Use Bindings for Dependency Injection – Cleaner initialization.
  • Wrap Only What Changes in Obx – For performance.
  • Follow Folder Structure – controllers/, pages/, services/ for large apps.
  • Combine With Clean Architecture – GetX works well with MVVM or layered structures.

FAQs:

Q1: Is GetX still relevant in 2025?
➡ Yes, it’s stable, fast, and widely used.

Q2: Can I use GetX only for navigation?
➡ Yes, you can use only the parts you need (navigation, DI, or state management).

Q3: Is GetX good for large projects?
➡ Yes, but follow clean architecture and avoid putting all logic in controllers.

Q4: Which is better in 2025: GetX or Riverpod?
➡ GetX is easier for beginners and small–medium projects. Riverpod is good for very complex apps.

Q5: Does GetX support Flutter Web and Desktop?
➡ Yes, it works across all Flutter platforms.

Conclusion:

At BaseProgrammer.com, we strongly recommend to take advantage of GetX in 2025 since it still happens to be one of the most powerful and developer-oriented solutions in the Flutter ecosystem. While other libraries focus on a single feature, GetX provides an out-of-the-box all-in-one package of state management, navigation, and dependency injection. Not only does this reduce boilerplate code to the minimum, but it also keeps your app clean, reactive, and very scalable. With low overhead and minimum learning curve, developers can build faster and still enjoy great performance. Whether new or seasoned Flutter master, GetX offers productivity and usability
