In the future a hook may be invoked multiple times with different `supportedAssetTypes` (soon to be renamed to `buildAssetTypes`). The hook should only emit those asset types that are in `supportedAssetTypes` - anything else is an error. Right now flutter happens to invoke hooks only with `Code` asset types, but more asset types are coming, for which this PR is a preparation for.
