Search View doesn't update size on navigator resize #186154
Description
Steps to reproduce
- Use full screen search view (SearchAnchor).
- Rotate phone/expand window.
- Search view has outdated forced constraints.
Alternatively if navigator is resized to not be covered by keyboard:
- Open keyboard (for example long press to search bar inside of search anchor).
- Open search view.
- Close keyboard.
- View is clipped at the bottom because navigator was initially small.
Expected results
View should update viewMaxWidth to match new constraints.
_SearchViewRoute should call updateTweens when Navigator.size changes.
It seems that _viewRect is provided from evaluated tween (animation) and also updated in _ViewContentState.didChangeDependencies using media query (which is incorrect and should actually use Navigator.size, because navigator can be resized in response to opened/closed keyboard)
Actual results
View is stuck with old size constraints.
