How to present an empty view in flutter?

There are many possible solutions of it. Like

1. Widget build(context) => Container();
   

2. Widget build(context) => SizedBox();
   

3. Widget build(context) => Scaffold();
   

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(

    );
  }
}

You can also simply return an empty Container and avoid using the Scaffold entirely. But this would result in a black screen if this is the only primary widget in you app, you can set the color property of the Container if you want to prevent the black background.

Example:

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.white // This is optional
    );
  }
}

For anyone like me who was wondering what is "the correct way" to show an empty widget - official Material codebase uses this:

Widget build(BuildContext context) {
  return SizedBox.shrink();
}

SizedBox.shrink() is a widget that is unlike Container or Material has no background or any decorations whatsoever. It sizes itself to the smallest area possible, if not influenced by parent constraints.
