I faced with this problem: I found the only way to do so that the background of the button was in full height when using safearea on iPhone 11. But now the button is pressed partially podskajet. Please how to make the entire blue area pressed as a button. Thank you all for your answers. I add a screenshot and a piece of code as it is implemented now.
Container(
color: Colors.blue,
child: SafeArea(
left: false,
right: false,
child: Expanded(
flex: 1,
child: SizedBox(
width: double.infinity,
child: RaisedButton(
elevation: 0,
onPressed: () {},
child: Text("Add", style: TextStyle(color: Colors.white)),
color: Colors.blue,
),
),
),
),
),
