What is the purpose of the "BuildContext" object in Flutter?
The `BuildContext` object is a fundamental part of the Flutter framework that provides information about the location of a widget in the widget tree hierarchy. It is a representation of the current context of a widget, which includes information about its location, theme, and dependencies.
The `BuildContext` is used by Flutter to perform various tasks such as building the widget tree, handling state changes, and managing animations. It is passed down from the root of the widget tree to all of its child widgets, allowing them to access information about their parent widget and the overall application context.
The `BuildContext` object is often used when creating widgets, especially when instantiating widgets that depend on the current context, such as `Scaffold`, `Theme`, `MediaQuery`, and `Navigator`. It is also used to perform various actions such as displaying dialogs, making network requests, and updating state.
