FlViewRenderer:

#FlViewRenderer is a GTK widget that renders the contents of a Flutter view. It owns the compositor and OpenGL context used to draw frames produced by the Flutter engine. Input handling and other view responsibilities are handled by #FlView. fl_view_renderer_new: @engine: the #FlEngine to render. @sized_to_content: TRUE if the view size is controlled by Flutter.

Creates a new widget that renders Flutter frames.

Returns: a new #FlViewRenderer.
