Environment: The Flutter Web Skia backend.

Problem: Load image using Image.memory or Image.network, change difference image randomly. Check memory usage in Chrome or Safari, the heap memory increase and never collected.

The SkAnimatedImage cause the problem, the skiaInstantiateImageCodec method always return an SkAnimatedImage instance, the dispose may not clear memory expectantly.

Try to replace MakeAnimatedImageFromEncoded to MakeImageFromEncoded, problem solved.
