I need a lightweight Android app built in Flutter that lets users create an account and sign in through a clean, modern interface. The scope is intentionally small—just a polished login / registration flow, basic form validation, and the wiring to hit a simple authentication API that I’ll supply (JSON over HTTPS). No strict brand rules are in place, so you’re free to suggest colours, typography, and any subtle animations that keep the experience professional yet friendly. Because this project is primarily to test the waters on Google Play, I’m aiming for a fast turnaround and an affordable quote. Newer freelancers looking to build up reviews are welcome as long as code quality is solid and well-commented. Deliverables • Complete Flutter source code • Release-ready APK (Android 12+) • One-page setup & build guide When you apply, include your best price, estimated delivery time, and links to any similar work—simple auth screens, onboarding flows, or small utility apps are perfect examples. The award will go to the proposal that balances cost, clarity, and speed.

Hi there, Your login and registration flow is the part users judge in seconds , and the hidden risk is a polished screen that still feels fragile under the hood. I can build your lightweight Flutter Android app with a clean UI, solid form validation, and secure HTTPS API integration so the first Play Store test feels smooth and credible. I’ve built app-facing forms and API-connected flows before, and I’ll keep the code structured, well-commented, and easy to extend if you later add password reset, onboarding, or social login. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you want, I can start by matching the auth API contract and shaping the screens around your preferred visual style. Could you share the exact API endpoints, expected JSON payloads, and whether you want any local session persistence? Also, do you need the APK signed for Play Console testing or just a release-ready build? Looking forward to your reply so we can finalize the exact plan. Thanks, Asad

Hi there, I have read your project requirement. You need a lightweight Flutter application with a clean and modern login and registration experience, including form validation and integration with your existing JSON-based authentication API. The focus is on delivering a polished, user-friendly app with maintainable code and a fast turnaround. We have experience building Flutter applications, authentication flows, API integrations, and responsive mobile interfaces. We can deliver clean, well-structured source code, a release-ready APK, and clear setup documentation. A few questions: =============== Does your authentication API support JWT tokens, refresh tokens, or another authentication mechanism? Besides login and registration, do you require features such as password reset or email verification? Do you already have API documentation available for integration? Should user sessions remain active after app restarts, or should users log in each time? Best Regards, Srashtasoft Team
