tap method Null safety
Dispatch a pointer down / pointer up sequence at the center of the given widget, assuming it is exposed.
The warnIfMissed
argument, if true (the default), causes a warning to be
displayed on the console if the specified Finder indicates a widget and
location that, were a pointer event to be sent to that location, would not
actually send any events to the widget (e.g. because the widget is
obscured, or the location is off-screen, or the widget is transparent to
pointer events).
Set the argument to false to silence that warning if you intend to not actually hit the specified element.
For example, a test that verifies that tapping a disabled button does not
trigger the button would set warnIfMissed
to false, because the button
would ignore the tap.
Implementation
Future<void> tap(Finder finder, {int? pointer, int buttons = kPrimaryButton, bool warnIfMissed = true}) {
return tapAt(getCenter(finder, warnIfMissed: warnIfMissed, callee: 'tap'), pointer: pointer, buttons: buttons);
}
