The BuildContext in Flutter is an object that holds information about the context the Widget is in. Most importantly it holds where in the Widget-tree our Widget is located. This is why we need the BuildContext to get a certain Provider, ThemeData or MediaQuery for instance.
Without the BuildContext belonging to the Widget we are in, Flutter has no way of knowing WHERE (in the Widget-tree) to look for the Data we are looking for.
Same goes for Navigation, we need to know where we are coming from, to go somewhere new.
