Make `flutter_app` work on flutter `master` channel
The flutter_app example code doesn't compile and run as is on checkout. The dependencies fail to resolve, and the app requires the DamagedHelmet.glb model which isn't part of the checkout.
Ah yeah, this is a leak from my stage because I didn't want to check in large models. Now that I've replaced the importer scripts, maybe some CI stuff is in order soon. I'm also considering adding a bootstrap script that downloads all the glTF sample assets.
Do you want me to trim this down to parts you are willing to land, or should I just close it?
The former. Everything LGTM except the dependency pin. Apologies for the ambiguity.
Reverted the dependency pin.
