checkAndAddDeps method

Future<void> checkAndAddDeps({ required Config config, required String workingDirectory, })

Checks the target project for required dependencies and installs any missing ones.

Dependencies are added via dart pub add to keep the project in a valid state (it updates pubspec.yaml and runs pub get). This includes packages needed for either bloc or riverpod generation.
