FocusNode explained for Android Developers

FocusNode objects are persistent and form a focus tree that represents the widgets in the hierarchy that are interested in focus. They can be managed directly or through utility widgets like Focus and FocusScope. This is somewhat similar to how Android handles focus with Views, where you can request focus and manage focusable elements in a layout.

Example Code

Here is an example of how to use FocusNode:

FocusNode focusNode = FocusNode();
