GetX is an extra-light and powerful solution for Flutter. It combines high-performance state management, intelligent dependency injection, and route management quickly and practically.
So, we will see how you can use GetX to create a dialog in Flutter Let's start
Step 1: Create a new Flutter Application.
Step 2: Add a line like this to your package's pubspec.yaml
|
Step 3: Once installed replace your MaterialApp with GetMaterialApp for example
|
GetMaterialApp( debugShowCheckedModeBanner: false, theme: ThemeData( primarySwatch: Colors.teal, ), home: HomePage(), ); |
then you can create a button when pressed will open the dialog in Flutter, as early we have to write a lot of code to create a dialog with GetX Library you can simply use Get.defaultDialog() to open the Dialog.
for example:
|
ElevatedButton( onPressed: () { Get.defaultDialog(); }, child: const Text('Open Dialog'), ), |
Result:
 |
Step 4: Now you saw how easy it is to get a dialog with very few lines using GetX in Flutter. You can also customize it with different options given by GetX.
for example:
|
Get.defaultDialog( title: 'Title Text', middleText: 'Message Extra Text is here', textCancel: 'Cancel', textConfirm: 'Ok', confirmTextColor: Colors.white, cancelTextColor: Colors.black, radius: 10, backgroundColor: Colors.teal.shade100); |
Complete example code for Create Dialog using GetX

import 'package:flutter/foundation.dart'; import 'package:flutter/material.dart'; import 'package:get/get.dart';
void main() { runApp(MyApp()); }
class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return GetMaterialApp( debugShowCheckedModeBanner: false, theme: ThemeData( primarySwatch: Colors.teal, ), darkTheme: ThemeData( primarySwatch: Colors.teal, brightness: Brightness.dark, ), home: HomePage(), ); } }
class HomePage extends StatefulWidget { const HomePage({Key? key}) : super(key: key);
@override State createState() => _HomePageState(); }
class _HomePageState extends State { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('GetX Dialog Demo'), ), body: Center( child: ElevatedButton( onPressed: () { Get.defaultDialog( title: 'Title Text', middleText: 'Message Extra Text is here', textCancel: 'Cancel', textConfirm: 'Ok', confirmTextColor: Colors.white, cancelTextColor: Colors.black, radius: 10, backgroundColor: Colors.teal.shade100); }, child: const Text('Open Dialog'), ), ), ); } }
