Flutter App Update & Password Fix

I'm facing a critical issue with my Flutter app - users' passwords are not being accepted during verification, which is impacting the app's functionality. The app currently uses email and password for authentication. In addition to resolving the password verification issue, I need a professional who can fully update the app to make it functional again. This includes identifying and fixing bugs, as well as implementing optimizations for better performance. Ideal Skills and Experience: - Expertise in Flutter development - Strong background in troubleshooting and debugging - Experience with implementing app optimizations - Proficient in UI/UX improvements - Familiarity with email/password authentication systems
