Flutter app leaves blank space at the top of the screen when removing system overlays

When removing system overlays with SystemChrome.setEnabledSystemUIOverlays([]) the app does not expand to fill the screen.

Complete main.dart file:

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  SystemChrome.setEnabledSystemUIOverlays([]);
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Container(
        color: Colors.red,
      ),
    );
  }
}

Without SystemChrome.setEnabledSystemUIOverlays([]):
