generateMacosCode function

Future<bool> generateMacosCode({ required DesktopSplashConfig config, required String flavor, required Directory outputDir, })

Generates Macos platform-specific code for the native splash screen

Takes a config object containing splash screen configuration, a flavor string to support multiple build flavors, and an output outputDir to override the default location.

Returns true if generation was successful, false otherwise.

Implementation

Future<bool> generateMacosCode({
  required DesktopSplashConfig config,
  required String flavor,
  required Directory outputDir,
}) async {
  if (!File(config.imagePath).existsSync()) {
    logger.e('Image file not found: ${config.imagePath}');
    return false;
  }
