With Flutter 1.22 we received a new widget OutlinedButton
which is made to replace OutlineButton
but how we can actually make its border rounded? borderSide
and shape
properties are not available anymore.
You can use OutlinedButton.styleFrom
property:
OutlinedButton(
style: OutlinedButton.styleFrom(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
),
side: BorderSide(width: 2, color: Colors.green),
),
onPressed: () {},
child: Text('Button'),
)
From the source code
/// All parameters default to null, by default this method returns
/// a [ButtonStyle] that doesn't override anything.
///
/// For example, to override the default shape and outline for an
/// [OutlinedButton], one could write:
///
/// ```dart
/// OutlinedButton(
/// style: OutlinedButton.styleFrom(
/// shape: StadiumBorder(),
/// side: BorderSide(width: 2, color: Colors.green),
/// ),
/// )
/// ```
Screenshot:
If you need some extra control over the style like border should be ABC when the button is pressed, DEF when its hovered... XYZ when not interacted, you can use ButtonStyle
.
OutlinedButton(
onPressed: () {},
style: ButtonStyle(
shape: MaterialStateProperty.resolveWith<OutlinedBorder?>((states) {
// Rounded button (when the button is pressed)
if (states.contains(MaterialState.pressed)) {
return RoundedRectangleBorder(borderRadius: BorderRadius.circular(20));
}
}),
),
child: Text('OutlinedButton'),
)
