The Mobile App Development with Flutter Proficiency (Advanced Level) benchmark evaluates your knowledge of accessing data from HTTP endpoints, serializing and deserializing JSON data, making HTTP requests, local persistence methods, storing data using the file system and SharedPreferences, and locally persisting data using SQLite. You will be assessed on your skills in knowing when to choose ephemeral state vs. app state, integrating with the Firebase backend, storing data in Cloud Firestore, writing unit and widget tests for Flutter apps, using mocks in unit tests, and using the DevTools suite for debugging. Learners who score high on this benchmark demonstrate that they have the skills to work with the backend in Flutter.
