createEmbeddedView method
Instantiates an instance of the provided template.
Implementation
EmbeddedViewRef createEmbeddedView() {
// The unsafe cast is necessary because a view container's parent may be any
// kind of view, but this method is only ever called when the parent view is
// a `RenderView`.
final parentView = unsafeCast<RenderView>(_viewContainer.parentView);
final view = _viewFactory(parentView, _viewContainer.index);
view.create();
return view;
