Separating dev and production environment in your Flutter App with multiple Firebase configurations.

Short summary

Use Flutter Flavors to create distinct dev and production app variants from a single codebase, each connected to its own Firebase project. Configure flavor-specific Firebase credentials in build.gradle for Android and Xcode schemes for iOS, then set up separate Dart entry points that initialize the correct Firebase options. This eliminates test-data pollution, prevents debug notifications from hitting production users, and lets you test both versions on one device.
