Answer 1

import 'package:flutter/material.dart';

void main() => runApp(App());

class App extends StatelessWidget {

  @override
 
 Widget build(BuildContext context) {
    
   return MaterialApp(
    
      home: Scaffold(
      body:HomePage(),
      ),
    );
   }

}


class HomePage extends StatelessWidget {

  @override

  Widget build(BuildContext context) {

    var size = MediaQuery.of(context).size.height;

    return Container(
      height:size/2,
      color:Colors.lightBlueAccent,
        
    );
  }

}
