I’m stuck with a compilation error that appears the moment I try to build my Flutter app. The project fails during flutter build, so the APK never generates and I can’t move forward with testing. It isn’t a runtime or interface issue—just a build-time blocker. You’ll have full access to the repository to reproduce the problem locally. I need you to trace the root cause, apply a clean fix, and push the working code back to me. Acceptance once: • flutter pub get • flutter build apk (or ipa) Both must complete without errors on my machine, and you’ll include a short note summarising what you changed and why. If you’re confident troubleshooting Flutter compilation issues and dependencies, I’d appreciate your help.
