projectAssetChecks function

List<DoctorCheck> projectAssetChecks(Directory project)

What doctor says about a project's models (decision 54): whether a hook is there to convert what is under assets_src/, and whether flutter: assets: names every directory the converted files land in.

Both fail nothing, which is why both are problems here. Without the hook nothing is converted, and Model3D finds no file; without a line for flutter3d_generated/models/ the build bundles the files directly in flutter3d_generated/ and none below it, since Flutter does not bundle a directory's subdirectories. A project with nothing under assets_src/ that converts gets no line.
