Get the Global Context in Flutter

Question

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.

Answer 1

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}");
