Public Member Functions inherited from flutter::EmbedderRenderTarget
virtual	~EmbedderRenderTarget ()
	Destroys this instance of the render target and invokes the callback for the embedder to release its resource associated with the particular backing store.
const FlutterBackingStore *	GetBackingStore () const
	The embedder backing store descriptor. This is the descriptor that was given to the engine by the embedder. This descriptor may contain context the embedder can use to associate it resources with the compositor layers when they are given back to it in present callback. The engine does not use this in any way.

Additional Inherited Members
Protected Member Functions inherited from flutter::EmbedderRenderTarget
	EmbedderRenderTarget (FlutterBackingStore backing_store, fml::closure on_release)
	Creates a render target whose backing store is managed by the embedder. The way this render target is exposed to the engine is via an SkSurface and a callback that is invoked by this object in its destructor.
