Thanks for the video! I can't believe there is no some elegant solution for this task built in Flutter. It would be great to have an ability to update parent widget using some predefined methods of the parent object accessible via the "context" variable (passed to the build method of the childWidgetState). Because when there are lots of child widgets (for example items in a list) it would be kinda wasteful to store a reference to the same function inside of every child object.
