Extensions

Overview

GetX offers tons and tons of extensions. Some provide useful information, while others minimize verbose code. Using these extension methods regularly, we can save a good chunk of development time. So let’s look at some of the most helpful ones!

Context extensions

BuildContext is an object in Flutter that provides access to a widget’s location in the widget tree. It is used to retrieve information about the widget’s location and ancestors and to perform operations like navigation and accessing inherited widgets.

Extensions on BuildContext give us information related to screen dimensions and orientation, and also the app’s theme. Since the information is extracted from the current context, it automatically updates when we resize the app window or rotate our device. This can come in handy when we’re building responsive applications.
