void _showAlertDialog(BuildContext context) { showCupertinoModalPopup<void>( context: context, builder: (BuildContext context) => CupertinoAlertDialog( title: const Text('Alert'), content: const Text('Are you sure want to update the data?'), actions: <CupertinoDialogAction>[ CupertinoDialogAction( isDefaultAction: true, onPressed: () { Navigator.pop(context); }, child: const Text('No'), ), CupertinoDialogAction( isDestructiveAction: true, onPressed: () { Navigator.pop(context); }, child: const Text('Yes'), ), ], ), ); } |
3.) Use the CupertinoDialogAction widget.
