I want an expert in Flutter/UX to build an App with following specification. The person should be proactive in suggesting features and UX elements that might help the app. Resource utilization (CPU, Memory) by App is also an important criteria.
1 Registration - 3 fields
2. Login - Auto with backend, Based on locally saved credentials
3. Rewards screen - Updated from backend
4. Activity selection/ scheduler screen - Swipe based
5. Camera activity loop that will be running in context of Native platform (Java, Objective-C).
There might be some other features and details.
