Попробуйте тогда,

import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'NonStopIO',
theme: new ThemeData(
primarySwatch: Colors.red,
),
home: new MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
bool _rememberMeFlag = false;
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text('NonStopIO'),
),
body: new Container(
color: Colors.black38,
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Container(
