Targets -> Runner -> Build Phase: Add script to copy correct GooglePlaySerivce file for the correct scheme.

Copy the config folder into the Xcode (drag and drop under Runner project).

Copy GooglePlayServices files under config/dev and config/prod.We need to setup custom schemes at iOS side to support multiple variants. Let's create dev and prod environments(a.k.a Schemes) at iOS platform. That is all you need to enable flavors on Android side. ResValue 'string', 'app_name', 'Counter App Prod'

ResValue 'string', 'app_name', 'Counter App Dev' VersionCode flutterVersionCode.toInteger() The dev flavor/variant of app uses one instance of Firebase project, and prod flavor uses different instance of Firebase project.Ĭreate a class AppConfig to encapsulate the app's environment/flavor type and specific name for that flavor. Let's assume this app uses Firebase for backend. In this article, I will use default CounterApp in two variants or flavors: dev for development, and prod for production. Let's call this variant of app as prod flavor. When you are ready to roll-out the application for public release and have production backend ready, you need a variant of same app which is connected to the production backend. If you want to distribute your app to internal testers, you need a dev variant for the application. During development stage, you may want to share your app to internal testers with a backend configured for development but not ready for production purpose. In real-world applications development process, there are multiple environments and/or stages an applications is released in. In this article, I will give overview of the process of publishing Flutter applications on Android and iOS platforms in multiple environments. Recipe: Publish Flutter application on Android and iOS platforms for development(dev) and production (prod) environments.

Flutter build apk android studio
