element<T extends Element> method
Null safety
- Finder finder
The matching element in the widget tree.
Throws a StateError if finder
is empty or matches more than
one element.
- Use firstElement if you expect to match several elements but only want the first.
- Use elementList if you expect to match several elements and want all of them.
Implementation
T element<T extends Element>(Finder finder) {
TestAsyncUtils.guardSync();
return finder.evaluate().single as T;
}
