You can check breaking-changes/buttons

enter image description here

To have the same visual look

final ButtonStyle flatButtonStyle = TextButton.styleFrom(
  foregroundColor: Colors.black87,
  minimumSize: Size(88, 36),
  padding: EdgeInsets.symmetric(horizontal: 16.0),
  shape: const RoundedRectangleBorder(
    borderRadius: BorderRadius.all(Radius.circular(2.0)),
  ),
);

TextButton(
  style: flatButtonStyle,
  onPressed: () { },
  child: Text('Looks like a FlatButton'),
)
