Flutter Productivity App with Auth

I need a skilled Flutter developer to turn my concept for a cross-platform productivity app into a polished, store-ready release. The core of the build is an intuitive task-management workflow where users can create, edit, prioritise and complete tasks. Secure user authentication is mandatory—email/password is essential, and I’m open to social sign-ins if it fits naturally into your architecture.

You’ll design the UI in Flutter, wire it to a clean state-management solution and connect it to either a Firebase or REST back-end (I have both options prepared). Smooth performance on both iOS and Android, thoughtful error handling and tidy, well-commented code are all part of the brief.

Deliverables
• Full Flutter source code in a private Git repo
• Auth flow fully implemented and tested
• Task-management screens and logic complete, pixel-perfect to Figma files I’ll supply
• Release-ready builds (APK & IPA) plus deployment guidance
• Basic README covering build steps, package versions and any environment variables

I’ll test against a short acceptance checklist: a new user can sign up, log in, add a task, mark it complete, and see that state persist after relaunch.

If you’ve shipped similar productivity or task apps before, that context will be a plus—feel free to reference it when you respond.
