Another nice thing about switching from a dynamic return type to Object? is that for function components, you get an analysis warning if you forget to return something.

This actually seems like a breaking change, so unfortunately I think we'll have to change the return type of JsFunctionComponent/JsForwardRefFunctionComponent and Component(2).render back to dynamic

Motivation
In React, a "React node" is a value that can be returned from a component's render or used as children, and contains more values than just
ReactElement.TypeScript captures this type as a
ReactNodetypeNow that Dart has type aliases (in SDK 2.13 and up), can name this type so that consumers can be more expressive in how they type their code (and also to help them avoid using
ReactElement, which in some cases is overly restrictive).Changes
ReactNodetypedef, which is an alias forObject?.
