getHeight()

int io.flutter.embedding.engine.renderer.SurfaceTextureSurfaceProducer.getHeight ( )

inline

Returns

The currently specified height (physical pixels)

Implements io.flutter.view.TextureRegistry.SurfaceProducer.

getSurface()

Surface io.flutter.embedding.engine.renderer.SurfaceTextureSurfaceProducer.getSurface ( )

inline

Get a Surface that can be used to update the texture contents.

NOTE: You should not cache the returned surface but instead invoke getSurface each time you need to draw. The surface may change when the texture is resized or has its format changed.

Returns

a Surface to use for a drawing target for various APIs.

    return surface;
  }

getSurfaceTexture()

SurfaceTexture io.flutter.embedding.engine.renderer.SurfaceTextureSurfaceProducer.getSurfaceTexture ( )

id()

long io.flutter.embedding.engine.renderer.SurfaceTextureSurfaceProducer.id ( )

inline

Returns

The identity of this texture.
