# fullscreen:changed embed event

> Emitted by Omni when the fullscreen state of an embedded dashboard or app changes.

Omni emits this event whenever fullscreen mode is entered or exited through any mechanism: the menu item, keyboard shortcut, native `Esc` key exit, or unmount while fullscreen.

This event is emitted for both dashboards and apps. It does not fire on initial mount.

</ParamField>
