AssetBytesLoader class

Loads vector graphics data from an asset bundle.

This loader does not cache bytes by default. The Flutter framework implementations of AssetBundle also do not typically cache binary data.

Callers that would benefit from caching should provide a custom AssetBundle that caches data, or should create their own implementation of an asset bytes loader.
