View class

Injects a FlutterView into the tree and makes it available to descendants within the same LookupBoundary via View.of and View.maybeOf.

The provided child is wrapped in a MediaQuery constructed from the given view.

In a future version of Flutter, the functionality of this widget will be extended to actually bootstrap the render tree that is going to be rendered into the provided view. This will enable rendering content into multiple FlutterViews from a single widget tree.

Each FlutterView can be associated with at most one View widget in the widget tree. Two or more View widgets configured with the same FlutterView must never exist within the same widget tree at the same time. Internally, this limitation is enforced by a GlobalObjectKey that derives its identity from the view provided to this widget.
