Tests on macOS cannot simulate the enter key triggering the onEditingComplete method of a TextField. #156414
Description
Use case
When creating tests for #156412, I was unable to simulate the enter key triggering onEditingComplete for the TextField. When I used simulateKeyDownEvent(LogicalKeyboardKey.enter), it always sent the insertNewline message due to the code at
tester.binding.testTextInput.receiveAction(TextInputAction.done) also does not satisfy this case, because I am not always sure that the focus is on the TextField.
Proposal
Provide a way to simulate the enter key triggering the onEditingComplete method of a TextField.
