Get the Global Context in Flutter

Is there any way to get the global context of Material App in Flutter. Not the context of particular screen.

I am trying to get the context but it gives me the context of particular screen but I want the context of MaterialApp.

Just wrap with GetMaterialApp and when you can use Get.context! to use context Anywhere

If you use Getx State Management you can use;

GetMaterialApp(
      navigatorKey: Get.key,  
    );

Reach out with;

  BuildContext? context = Get.key.currentContext;

If above solution does not works please try this solution.

  1. Create the class. Here it named as NavigationService

    import 'package:flutter/material.dart';

class NavigationService { 
  static GlobalKey<NavigatorState> navigatorKey = 
  GlobalKey<NavigatorState>();
}

  2. Set the navigatorKey property of MaterialApp in the main.dart

    Widget build(BuildContext context) {
  return MaterialApp(
    navigatorKey: NavigationService.navigatorKey, // set property
  )
}

  3. Great! Now you can use anywhere you want e.g.

    print("---print context: 
  ${NavigationService.navigatorKey.currentContext}");

Assign a GlobalKey() to the MaterialApp which you can put in a separate class, let's call it App :

 @override
    Widget build(BuildContext context) {
      return MaterialApp(
        navigatorKey: App.materialKey, // GlobalKey()
      )
    }

Now wherever you want to get the context of the MaterialApp, you just have to call :

App.materialKey.currentContext

Here I'm printing MaterialApp context :

print('Material App Context : ${App.materialKey.currentContext}');

OUTPUT : flutter: Material App Context : MaterialApp-[GlobalKey#4fab4](state: _MaterialAppState#4bb44)
