What is BuildContext and how is it useful?

Posted by Jessica Taylor | Updated on

BuildContext is actually the widget’s element in the Element tree — so every widget has its own BuildContext.

You usually use BuildContext to get a reference to the theme or to another widget. For example, if you want to show a material dialog, you need a reference to the scaffold. You can get it with Scaffold.of(context), where context is the build context. of() searches up the tree until it finds the nearest scaffold.
