I already have the complete Flutter codebase for my online Matka app; it simply needs a refresh. Your tasks are straightforward: • Repoint the base URL so every call now targets a different API endpoint. • Remove or upgrade any deprecated packages and migrate the project to the latest stable Flutter version. Once those adjustments are in place, compile a clean, release-ready build. I expect the updated source (pushed back to my repo) and a signed APK; an iOS build is a bonus if you have the setup. Please ensure the app runs without warnings after flutter analyze, all existing features remain intact, and you provide a concise changelog describing the edits.

I do this kind of Flutter code migration and API repoint routinely—package cleanup, SDK upgrade, swap endpoints, build and test until flutter analyze is clean. I won’t touch any in-app Matka/game logic. I’ll work through your repo, update the endpoint in all relevant services, clear out deprecated plugins, fix any breaking changes, and bump the codebase to the latest Flutter stable. You get back a release APK, updated source, and a changelog that details every edit. iOS build is possible if the provisioning profiles and certificates are provided. Is your existing API structure staying the same, or did the new endpoint change any response formats? Pradeep
