Easy Dialogs using GetX

May 2, 2021 2 min read


If you have read my post about snackBars using GetX, You already know how easy is it to work with GetX in Flutter.

Dialogs are an essential part of mobile Apps. They help to convey alerts and important messages as well as to do certain actions.

Normally in Flutter, shown below is a sample code for showing and Alert Dialog.

 context: context,
 builder: (context) => AlertDialog(
      title: Text(
          content: Text(
              "This is sample Content",

That’s too many Lines of code for a Simple Dialog like this. But, thankfully GetX makes this easier. In GetX, we only have to use the following code,

 title: "Alert",
 content: Text(
   "This is a sample Content",

I think this makes a big difference.

Add Package

First of all, we have to add the get package into our pubspec.yaml file

    sdk: flutter
  get: ^4.1.4 # Get the latest version from https://pub.dev/packages/get

Change to GetMaterialApp

To all navigation and routing things work with GetX, we have to change our MaterialApp to a GetMaterialApp. For this, we have to import the library first

import 'package:get/get.dart';

class MyApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return GetMaterialApp( // Changed from MaterialApp to GetMaterialApp
      home: HomePage(),

If this step is not completed, it will throw an error when we try to use something like Get.dialog().

We’re good to go now.

GetX default Dialog

This is the type of dialog which I have shown as an Example.

  title: "Alert!",
  content: Text("This is a sample Content"),

Put the above code inside any onPressed or onTap method and see the magic.

GetX Dialog

This is also a simple way to show a dialog. But in this, we don’t have parameters like title and content, But we have to construct them manually. It accepts a widget and we have to build our Dialog from Scratch.

  Text("This is a simple Dialog"),

the above code will show a simple dialog with the text, This is a simple Dialog. But it is not cool looking.

Get Dialog With Just Text

So we should always return a Dialog widget from Get.dialog and put anything we want to show the user as the child of the Dialog Widget.
