showPlatformAlertDialog<T> function

Future<T?> showPlatformAlertDialog<T>({ required BuildContext context, PlatformDialogData? platformDialogData, MaterialDialogData? materialDialogData, PlatformDialogData? cupertinoDialogData, MaterialAlertDialogData? materialAlertDialogData, CupertinoAlertDialogData? cupertinoAlertDialogData, Widget? title, Widget? content, List<Widget>? actions, Key? key, })

Shows a platform-adaptive alert dialog that renders Material AlertDialog on Android and CupertinoAlertDialog on iOS.

This function automatically selects the appropriate alert dialog implementation based on the target platform:

• On Android: shows a Material Design AlertDialog
• On iOS: shows a CupertinoAlertDialog

The alert dialog can be configured with platform-specific data through materialAlertDialogData and cupertinoAlertDialogData, or with common properties.

Example:

showPlatformAlertDialog(
  context: context,
  title: Text('Confirm'),
  content: Text('Are you sure you want to continue?'),
  actions: [
    PlatformDialogAction(
      child: Text('Cancel'),
      onPressed: () => Navigator.pop(context),
    ),
    PlatformDialogAction(
      child: Text('OK'),
      onPressed: () => Navigator.pop(context),
    ),
  ],
)
