Alert dialogs interrupt users with urgent information, details, or actions.

The dialog will position its buttons based on the available space. By default it will try to place them horizontally next to each other and fallback to horizontal placement if not enough space is available. There is also another version of this composable that has a slot for buttons to provide custom buttons layout.

Sample of dialog:
