BaseAlert class

BaseAlert - Cross-platform native alert dialogs

Uses native iOS UIAlertController via platform channels for iOS - provides authentic iOS alert dialogs with native styling and behavior. Uses Material AlertDialog for Android and other platforms.

Features:

• Native iOS/macOS alert dialogs via UIAlertController (platform channels)
• Material Design fallback for non-iOS platforms
• Consistent API across platforms
• Support for action styles (default, cancel, destructive)
• Preferred action highlighting
• Convenience methods for common alert patterns
• Automatic platform-specific conversion of actions

Example:

await BaseAlert.show(
  context: context,
  title: 'Delete Photo',
  message: 'Are you sure you want to delete this photo?',
  actions: [
    BaseAlertAction(
      title: 'Cancel',
      style: BaseAlertActionStyle.cancel,
    ),
    BaseAlertAction(
      title: 'Delete',
      style: BaseAlertActionStyle.destructive,
      onPressed: () {
        // Perform delete action
      },
    ),
  ],
);

Updated: 2024.10.25 - Renamed from BaseCNAlert for consistency
