getConfig function

Map<String, dynamic> getConfig({ required String? configFile, required String? flavor, })

Get config from pubspec.yaml or flutter_native_splash.yaml

Implementation

Map<String, dynamic> getConfig({
  required String? configFile,
  required String? flavor,
}) {
  // It is important that the flavor setup occurs as soon as possible.
  // So before we generate anything, we need to setup the flavor (even if it's the default one).
  _flavorHelper = _FlavorHelper(flavor);
  // if `flutter_native_splash.yaml` exists use it as config file, otherwise use `pubspec.yaml`
  String filePath;
  if (configFile != null) {

      filePath = configFile;
    } else {

      exit(1);
    }
  } else if (_flavorHelper.flavor != null) {
    filePath = 'flutter_native_splash-${_flavorHelper.flavor}.yaml';
