fl_accessible_node_new()

FlAccessibleNode* fl_accessible_node_new	(	FlEngine *	engine,
		FlutterViewId	view_id,
		int32_t	node_id
	)

fl_accessible_node_new: @engine: the #FlEngine this node came from. @view_id: the view ID this object represents. @node_id: the semantics node ID this object represents.

Creates a new accessibility object that exposes Flutter accessibility information to ATK.

Returns: a new #FlAccessibleNode.
