When you submit your app to the iOS app store, make sure to remove the alpha channel from your app icons, so your app doesn’t get rejected. Set android and ios to true to override the existing Flutter launcher icon for both platforms and define the icon image path. yaml and points to the flavor icon in the assets/icons/ folder. Each file is named flutter_launcher_icons- the flavor name. We have to create a configuration file for each of our flavors. This package will generate all of the icon sizes for Android and iOS and put them into the correct folders. In our pubspec.yaml, add the flutter_launcher_icons package as a dev dependency. Generate app icons with the flutter_launcher_icons packageĭrag your icons into assets/icons. We use this variable in our ist by creating a new key CFBundleDisplayName and setting it to APP_DISPLAY_NAME wrapped in parentheses with a dollar sign.įinally, set the FLUTTER_TARGET in the Build Settings to target each main.dart entry point based on the selected flavor. Note that if your app display name is longer than 12 characters, the spaces will be removed. Then set our app’s display name by creating a User-Defined variable called APP_DISPLAY_NAME. Here we set each configuration’s bundle identifier. In the Build Settings of Target Runner, make sure All and Combined are selected, and then search for bundle identifier. The production scheme already points to our production configurations, which means we don’t have to change them. Now let’s go into Manage Schemes and edit the development and staging schemes to point to the correct build configurations. Add the -production suffix to the original configuration. Next, we have to go into the Runner project and duplicate the Debug, Release, and Profile configurations for development and staging. Rename the original Runner to production. ![]() In Xcode, let’s create two new schemes called development and staging that both target Runner. IOS build configurations are more complicated than Android and can only be done in Xcode, so be sure to follow along closely. In our android/app/src/main/AndroidManifest.xml, we set the to set our app’s app name. This means our bundle identifiers will be: ![]() ResValue "string", "app_name", "Dev Flavor Example" ResValue "string", "app_name", "Stg Flavor Example" ResValue "string", "app_name", "Flavor Example" The name of the app for each build is defined in the resValue line and our applicationId has a suffix for staging and development. Inside of our app/adle, we add our product flavors for production, staging, and development. You cannot use the -flavor option.Īdding build flavors to Android is pretty straightforward. Exception: The Xcode project does not define custom schemes. When we tap run, we get an error about not being able to use the -flavor option, so let’s add our build flavors next. Now when we go to the Run tab, we see our three launch configurations. Each configuration has a name, request, type, program, and arguments. We have three configurations, one for each flavor. At the root of our project, create a launch.json file inside a folder called. Luckily, both of these are easily fixable with a launch.json file. Running this command in the terminal won’t allow us to utilize VSCode’s debugger.It’s annoying to type this out whenever we need to run a different app build.However, there are two problems with this: $ flutter run -flavor development -target lib/main_development.dart Once we add our Android and iOS flavors configurations, we’ll also have to include the flavor we want to run with -flavor Į.g. $ flutter run -target lib/main_development.dart To run a specific main file, we can use $ flutter run.Į.g. We first have to create three entry points, one for each flavor: main_development.dart, main_staging.dart, and main_production.dart. staging - Test out the app in a production-like environment.development - Build and test new features.You’ll learn how to create three Android and iOS flavors: App flavors allow us to create multiple versions of our app with the same codebase, making it easy to create and test new features without the risk of destroying production data. When developing apps, it’s very important to separate your development and production environments. ![]() Get immediate access to my Flutter for Beginners Course for FREE when you subscribe.
