addLayer method
- Layer layer
Adds a composited leaf layer to the recording.
After calling this function, the canvas property will change to refer to a new Canvas that draws on top of the given layer.
A RenderObject that uses this function is very likely to require its RenderObject.alwaysNeedsCompositing property to return true. That informs ancestor render objects that this render object will include a composited layer, which, for example, causes them to use composited clips.

Implementation
void addLayer(Layer layer) {
stopRecordingIfNeeded();
appendLayer(layer);
}
