matchChipSelected method
Expect that a Chip is selected or not selected.
Note that in addition to the standard options,
the selector can be a list of other selectors. With chips,
it is very common to verify that several of them are on or off
at the same time, and passing in a list is a concise way to do
so.
Implementation
Future<Widget> matchChipSelected(dynamic selector, {required bool selected}) async {
return matchWidgetValue(selector, ft.equals(selected), extraFrames: 1);
}
