TODOs should link to a bug. If there isn't one, file one first, then link to the bug like TODO(https://github.com/dart-lang/native/issues/...): Type restrictions...

Names aren't unique (eg two nested types, nested in different parent types, can have the same name). Use the declaration id instead.
Better yet, why not just have the dependency visitor construct a Set<Declaration> directly, rather than constructing a Set<String> and then looking up the declaration from the string?

Most of the types do not reference declarations directly (like function parameters, variable types), which therefore means that declarations need to be looked up eventually.
The lookup is done afterwards to prevent multiple lookups and just have a single lookup per visitation.

You shouldn't ever need to look up types by name or id, after parsing is complete. The AST already has references to the declarations. Check if the ReferredType is a DeclaredType.

You shouldn't have to re-parse these types from strings. We did all the parsing already, and now have a nice clean AST to work with. In this case you can just check if the type is a DeclaredType, and get its id or declaration or whatever. Also need to handle the OptionalType case.
This Pull Request is to add filtering support to the swiftgen tool.
