getProjectInfo method

Future<ProjectModel> getProjectInfo({ String pubspecPath = 'pubspec.yaml', })

Reads the pubspec.yaml file and extracts the project name.

Throws ReleaseManagerException if the file is missing, malformed, or if the name field is absent. This method will never crash with unhandled exceptions.

Implementation

Future<ProjectModel> getProjectInfo({String pubspecPath = 'pubspec.yaml'}) async {
  final file = File(pubspecPath);

  if (!file.existsSync()) {
    throw ReleaseManagerException(
      'pubspec.yaml not found at $pubspecPath.',
      details: 'Please ensure you are running this command from the root of a Flutter project.',
    );
  }

  try {
    final content = await file.readAsString();
    final yamlMap = loadYaml(content);

    if (yamlMap is! YamlMap) {
      throw const ReleaseManagerException('pubspec.yaml does not contain a valid YAML map.');
    }

    final projectName = yamlMap['name'];
    if (projectName == null || projectName is! String) {
      throw const ReleaseManagerException(
        'Project name is missing in pubspec.yaml.',
        details: 'Please ensure your pubspec.yaml has a "name" field.',
      );
    }

    return ProjectModel(name: projectName);
  } catch (e) {
    if (e is ReleaseManagerException) {
      rethrow;
    }
    throw ReleaseManagerException(
      'Failed to parse pubspec.yaml safely.',
      details: e.toString(),
    );
  }
