Package io.flutter.embedding.engine.renderer

## Class SurfaceTextureWrapper

- java.lang.Object
- - io.flutter.embedding.engine.renderer.SurfaceTextureWrapper

-     public class SurfaceTextureWrapper
      extends Object

  A wrapper for a SurfaceTexture that tracks whether the texture has been released.

  The engine calls `SurfaceTexture.release` on the platform thread, but `updateTexImage` is called on the raster thread. This wrapper will prevent `updateTexImage` calls on an abandoned texture.
