My Flutter app is stuck on two roadblocks and I need a seasoned pair of hands to unblock it fast. The project runs on the Stable channel and targets Android, iOS, and Web. After adding multi-language support with Flutter Intl, the Android release build refuses to compile. At the same time, Firebase Cloud Messaging is wired in but web notifications never arrive. Here’s what I need from you: • Restore a clean, working Android release build (APK/AAB), adjusting any build.gradle, manifest, or localization settings that are tripping it up. • Configure FCM for the web build so a test notification reaches the browser, including any required service-worker tweaks. • Provide a concise change log so I can reproduce the setup later. You should be fluent in Flutter, Firebase Cloud Messaging, and build troubleshooting (gradle, manifest, firebase_options.dart, service workers). Good communication and swift delivery are essential—ideally we wrap this up within a couple of days. If this sounds straightforward for you, I’m ready to share the repo and get started.
