Can you explain what is meant by context in Dart and how it is used?

In Dart, especially in the context of Flutter, the BuildContext is an object that provides access to the widget tree and its state. It is used to find parent widgets, access themes, localization, navigation, and other resources related to the current position in the widget tree.

For example, to access the application's theme or navigation, the context is often used:

ThemeData theme = Theme.of(context);
Navigator.of(context).push(...);

The context is a kind of "reference" to a place in the widget tree, allowing interaction with the environment and more flexible UI management.
