      // The callback relies on being executed on the UI thread (unsynchronised read of
      // mNativeView
      // and also the engine code check for platform thread in
      // Shell::OnPlatformViewMarkTextureFrameAvailable),
      // so we explicitly pass a Handler for the current thread.

Member Function Documentation

id()

long io.flutter.view.FlutterView.SurfaceTextureRegistryEntry.id ( )

inline

Returns

The identity of this texture.

Implements io.flutter.view.TextureRegistry.TextureEntry.

Definition at line 968 of file FlutterView.java.

                     {
      return id;
    }

release()

void io.flutter.view.FlutterView.SurfaceTextureRegistryEntry.release ( )

inline

Deregisters and releases all resources .

Implements io.flutter.view.TextureRegistry.TextureEntry.

        return;
      }

      // The ordering of the next 3 calls is important:
      // First we remove the frame listener, then we release the SurfaceTexture, and only after we
      // unregister
      // the texture which actually deletes the GL texture.
 
      // Otherwise onFrameAvailableListener might be called after mNativeView==null
      // (https://github.com/flutter/flutter/issues/20951). See also the check in onFrameAvailable.
      surfaceTexture().setOnFrameAvailableListener(null);
      textureWrapper.release();
