CupertinoAlertDialog

An iOS-style alert dialog.

An alert dialog informs the user about situations that require acknowledgement. An alert dialog has an optional title 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 text_style property.

To open this control, simply call the page.open() helper-method.

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