After users type their username and password and hit the Login button, the app fails to reach my server. No crash is thrown—it simply never connects. This behaviour began right after I pushed some updates to the backend API, so I suspect an endpoint, header-change, or SSL / CORS setting may be to blame, but I need a fresh set of eyes on both the Flutter side (Dart, http / dio) and the server call itself. Here’s what I need from you: • Pinpoint why the app can’t establish the connection immediately after credentials are entered. • Patch the Flutter code (or propose the minimal server tweak) so the request succeeds again. • Prove the fix with a quick screen-recorded test on at least one Android and one iOS build (emulator is fine). I’ll provide the repo, current API docs, and notes on the recent server changes as soon as we start. Let me know your preferred debugging approach and roughly how long you’ll need—once it’s connecting reliably, we’re done.

Hello there, I can investigate why your Flutter app fails to connect to the backend after login, review the Dart code (http/dio), check headers, endpoints, SSL, and CORS settings, and provide the minimal fix required on either the app or server side. I will also verify the fix with a screen-recorded test on both Android and iOS (emulator or real device). I have 11 years of experience in mobile development and backend integration, and have resolved similar API connectivity issues, ensuring secure and reliable communication between apps and servers. To proceed: 1. Could you share the repo and API documentation along with notes on the recent backend changes? 2. Are there any specific authentication headers, tokens, or certificates currently in use that we should be aware of? I can provide a detailed debugging plan and timeline after reviewing the materials. Best regards.

Hi, I can review both your Flutter code and backend API changes to identify why the login request isn’t reaching the server after credentials are submitted. I can debug whether the issue comes from an endpoint mismatch, missing/changed headers, SSL or CORS restrictions, and then patch the Flutter code or suggest the exact server-side tweak needed for the request to succeed again. Once fixed, I can run tests on both Android and iOS (emulator builds are fine) and provide a quick screen recording showing the login flow working correctly. This way, you’ll have a clear view of what caused the failure and how it was resolved, ensuring the connection is restored reliably. Best Regards, Mutahra Rehman

I can help fix your Flutter app’s login issue that started after your recent API update. The app fails to connect after entering credentials, likely due to endpoint, header, SSL, or CORS changes. My approach: Review Flutter login code (http/dio) and server changes to identify mismatches. Patch the Flutter request or propose a minimal server tweak to restore connectivity. Test the fix on Android and iOS emulators and provide a short screen recording as proof. Deliverables: Fixed login functionality. Screen-recorded test on both platforms. Brief explanation of the issue for future reference. Estimated time: 3–5 hours depending on server complexity. I’ll need access to your repo, API docs, and notes on recent backend changes. I use step-through debugging, network log inspection, and cross-platform testing to ensure the app connects reliably. I can get your login working again quickly and efficiently.

Hello, I can help you quickly debug and fix the login issue in your Flutter app. Since the problem started after backend updates, I’ll carefully check both sides—Flutter code (http/dio, headers, SSL, CORS) and the updated API endpoints. What I’ll do: Identify why the request fails right after login Adjust Flutter code or suggest minimal backend tweak Test and provide screen-recorded proof on Android & iOS (emulator). I have strong experience in Flutter + API integrations, SSL configs, and backend debugging, so I can resolve this efficiently. My approach is to start by reproducing the issue, inspect request/response logs, then patch the root cause. I can begin immediately and expect to finish in a few hours. Delivery: Same Day

Hi, I can help you debug and restore the login flow so your Flutter app connects to the server again. I’ll: Review both the Flutter client (Dart http/dio) and the server API changes (endpoints, headers, SSL/CORS). Identify exactly why the request fails after login. Apply a minimal fix—either in Flutter code or a small server adjustment. Verify with a screen-recorded test on Android + iOS (emulator). I’ve worked on similar issues before, including integrating APIs, handling auth headers, and fixing SSL/CORS mismatches. I can usually pinpoint and patch within a few hours once I see the repo + API docs.

I’ll debug by first checking Flutter client logs (http/dio) and inspecting API call flow, then verifying backend response/headers against recent changes. If it’s SSL, CORS, or endpoint mismatch, I’ll patch accordingly. I’ll reproduce and test on Android & iOS emulator. Estimated time: 3–5 hours depending on backend complexity.
