How to Solve No MediaQuery widget found Error?

Solution 1

You cant use MediaQuery without MaterialApp Widget To use MediaQuery.of() function, first, you need to wrap your widget with MaterialApp(), even after that, you may get the error. To solve this error fully, you need to place MaterialApp() widget like below:

import 'package:flutter/material.dart';
void main(){
  runApp(MyApp());
}

class MyApp extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
    return MaterialApp( 
      home: LoginScreen()             
    );
  }
}

class LoginScreen extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
     return Scaffold(
          body: Container( 
                //Now you can use MediaQuery
                 width: MediaQuery.of(context).size.width,
                 height: MediaQuery.of(context).size.height * 0.4, 
             )
       );
  }
}
