Flutter App Completion & Bug Fixing

I have an incomplete app written in Flutter that needs to be completed. The main focus is on bug fixing, specifically addressing crashes or errors occurring at the app startup.

Ideal Skills:
- Proficient in Flutter
- Strong debugging skills
- Experience in mobile app development
- Knowledgeable in UI/UX principles

Please bid only if you can efficiently address these issues and enhance the app's stability for a smooth startup.
