down method
Dispatch a pointer down event at the given downLocation
, caching the
hit test result.
Implementation
Future<void> down(Offset downLocation, { Duration timeStamp = Duration.zero }) async {
assert(_pointer.kind != PointerDeviceKind.trackpad, 'Trackpads are expected to send panZoomStart events, not down events.');
return TestAsyncUtils.guard<void>(() async {
return _dispatcher(_pointer.down(downLocation, timeStamp: timeStamp));
});
}
