# 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.

  - ### SurfaceTextureWrapper

    public SurfaceTextureWrapper(@NonNull SurfaceTexture surfaceTexture, @Nullable Runnable onFrameConsumed)
    A wrapper for a SurfaceTexture.

    The provided `onFrameConsumed` callback must be invoked when the most recent image was consumed.

    Parameters:
      `onFrameConsumed` - The callback after the `updateTexImage` is called.
