M3 Button MaterialStateProperty defaults don't resolve MaterialState.pressed #122250
Description
Many of the MaterialStateProperty defaults for the Button classes are defined like the example from ElevatedButton below. The MaterialState.pressed and MaterialState.hovered states are always reported together, so the resolved color is always the hovered one, since that clause is first. The order should be pressed then hovered, since hovered can occur without pressed.
MaterialStateProperty<Color?>? get overlayColor =>
MaterialStateProperty.resolveWith((Set<MaterialState> states) {
if (states.contains(MaterialState.hovered)) {
return _colors.primary.withOpacity(0.08);
}
if (states.contains(MaterialState.focused)) {
return _colors.primary.withOpacity(0.12);
}
if (states.contains(MaterialState.pressed)) {
return _colors.primary.withOpacity(0.12);
}
return null;
});
