Can you explain what the didChangeDependencies method means in the context of a component's lifecycle?

The didChangeDependencies method in Flutter is called after initState and every time the dependencies of the InheritedWidget that the current widget depends on change. This is useful when your widget depends on data provided through InheritedWidget (such as themes, localization, or other providers). In this method, you can update the state based on the changed dependencies.

Example usage:

@override
void didChangeDependencies() {
  super.didChangeDependencies();
  final theme = Theme.of(context);
  // Update state if the theme has changed
}

Thus, didChangeDependencies helps respond to changes in external data that the widget depends on.
