Question: I'm learning Flutter, and I'm starting from the very basics. I'm not using MaterialApp. What's a good way to set the background color of the whole screen?

Here's what I have so far:

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

void main() {
  runApp(new MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new Center(child: new Text("Hello, World!"));
  }
}

```

Some of my questions are:

* What's a basic way to set the background color?
* What exactly am I looking at, on the screen? Which code "is" the background? Is there a thing to set the background color on? If not, what's a simple and appropriate "simple background" (in order to paint a background color).

Thanks for the help!

The code above generates a black screen with white text:

Answer: 
```
Scaffold(
      backgroundColor: Constants.defaulBackground,
      body: new Container(
      child: Center(yourtext)

      )
)

```
```
home: Scaffold(
            backgroundColor:  Color(
                0xBF453F3F),

```

and done :)
