Sometimes the native assets can be in a weird state (for example if a user had misreported dependencies in their hook), and it would be nice if the native assets can just be all deleted to start from scratch. The cleanest solution would be to this as part of flutter clean.

It's probably cleanest to provide an API in package:native_assets_builder that can be called for this purpose. (The implementation of that API would most likely simply delete .dart_tool/native_assets_builder/ recursively.)
