◆ CreateExternalTexture()

std::unique_ptr< Texture > flutter::IOSContextNoop::CreateExternalTexture	(	int64_t	texture_id,
		NSObject< FlutterTexture > *	texture
	)

overridevirtual

Creates an external texture proxy of the appropriate client rendering API.

Parameters

[in]	texture_id	The texture identifier
[in]	texture	The texture

Returns: The texture proxy if the rendering backend supports embedder provided external textures.

Implements flutter::IOSContext.

         @"devices where Metal is used for rendering.");
  
   // Not supported in this backend.

 }

◆ GetBackend()

IOSRenderingBackend flutter::IOSContextNoop::GetBackend ( ) const

overridevirtual

Get the rendering backend used by this context.

Returns: The rendering backend.

Reimplemented from flutter::IOSContext.
