getDependencies method

Future<Set<String>> getDependencies()

Retrieves all dependencies listed in the pubspec.yaml file.

This method reads and parses the pubspec.yaml file, extracting:

• Regular dependencies (found under the dependencies key)
• Development dependencies (found under the dev_dependencies key)

Returns a Set containing the names of all dependencies.

Throws an Exception if the pubspec.yaml file is not found.

Implementation

Future<Set<String>> getDependencies() async {
  final pubspecFile = File(filePath);

  if (!pubspecFile.existsSync()) {
    throw Exception('❌ Error: The file "$filePath" was not found!');
  }

  final content = pubspecFile.readAsStringSync();
  final yamlMap = loadYaml(content) as Map;

  final dependencies =
      (yamlMap['dependencies'] as Map?)?.keys.toSet() ?? <String>{};
  final devDependencies =
      (yamlMap['dev_dependencies'] as Map?)?.keys.toSet() ?? <String>{};

  return {...dependencies, ...devDependencies};
}
