Should be able to subscribe to changes on properties of MediaQuery instead of all changes #102060
Description
Since flutter/engine#29281 during keyboard opening animation the root MediaQuery will be updated with each frame. There are a lot of widgets which might call MediaQuery.of(context) but not all depend on all of the MediaQuery properties. It would be more efficient to only rebuild those widgets which depend on the change in screen dimensions, but not the widgets which depend on the text scale factor, which presumably isn't changing with each frame.
