2 This is a slight simplification for ease of
reading. In practice, the tree might be more complex.

3 While work is underway on Linux and Windows,
examples for those platforms can be found in the Flutter desktop embedding
repository.
As development on those platforms reaches maturity, this content will be
gradually migrated into the main Flutter repository.

4 There are some limitations with this approach, for
example, transparency doesn’t composite the same way for a platform view as it
would for other Flutter widgets.

5 One example is shadows, which have to be
approximated with DOM-equivalent primitives at the cost of some fidelity.
