Bottom notch (iPhone X) not avoided by SafeArea when the Keyboard is open #29941
Description
Steps to Reproduce
The padding added by a SafeArea or calculated with a MediaQuery, correctly takes the bottom notch of an iPhone X style phone into account when the keyboard is closed.
But if the keyboard is open when the Scaffold have its parameter resizeToAvoidBottomInset set to false, the height of the bottom notch is not taken into account in the SafeArea, making the whole page shift down the size of the bottom notch.
I think the correct behavior for SafeArea/MediaQuery should be to still have a padding.bottom value the height of the notch to avoid inconsistency of the total available height depending on the keyboard state.
Example project:
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
MyHomePage({Key key}) : super(key: key);
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
resizeToAvoidBottomInset: false,
appBar: AppBar(
title: TextField(),
),
body: Column(children: <Widget>[
Expanded(child: Container(color: Colors.white,),),
Expanded(child: Container(color: Colors.red,),)
],),
),
);
}
}When clicking on the TextField to open the keyboard, the whole content of the Scaffold body will shift down since the SafeArea is not compensating for the notch anymore.
