tap method
Simulates a full tap (press + release) at the location of target.
target is resolved lazily — typically a Finder.textLocation result.
tester.tap(tester.find.textLocation('Submit'));
// or with raw coordinates:
tester.tapAt(5, 3);
Implementation
void tap(TapTarget target) {
final coords = target._resolve(this);
tapAt(coords.x, coords.y);
}
