Hides FlutterTextInputView
from iOS accessibility system so it does not show up twice, once where it is in the UIView
hierarchy, and a second time as part of the SemanticsObject
hierarchy.
This prevents the FlutterTextInputView
from receiving the focus due to swiping gesture.
There are other cases the FlutterTextInputView
may receive focus. One example is during screen changes, the accessibility tree will undergo a dramatic structural update. The Voiceover may decide to focus the FlutterTextInputView
that is not involved in the structural update instead. If that happens, the FlutterTextInputView
will make a best effort to direct the focus back to the SemanticsObject
.
