CupertinoAlertDialog class

An iOS-style alert dialog.

An alert dialog informs the user about situations that require acknowledgement. An alert dialog has an optional title, optional content, and an optional list of actions. The title is displayed above the content and the actions are displayed below the content.

This dialog styles its title and content (typically a message) to match the standard iOS title and message dialog text style. These default styles can be overridden by explicitly defining TextStyles for Text widgets that are part of the title or content.

To display action buttons that look like standard iOS dialog buttons, provide CupertinoDialogActions for the actions given to this dialog.

Typically passed as the child widget to showDialog, which displays the dialog.
