Flutter SafeArea Widget Examples – Avoid the Notch

The notch was introduce first in iPhone X, then was implemented in almost every Android phones. It comes in different shapes and sizes. Programming an app to make it suit with different notches is hard. So Google introduced SafeArea widget, which insets its child by sufficient padding to avoid intrusions by the operating system.

Th widget can do something like indenting the child by enough to avoid the status bar or a notch at the top of the screen.

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      backgroundColor: Colors.white,
      body: SafeArea(
          top: true,
          bottom: true,
          left: true,
          right: true,
          child: Row(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              Container(
                width: MediaQuery.of(context).size.width,
                height: 300,
                color: Colors.orange,
                child: Text('Container in SafeArea', style: TextStyle(color: Colors.white, fontSize: 26),),
              )
            ],
          )),
    );
  }
}
