A flutter utility to easily create flavors in your flutter application

Let's start by setting up our environment in order to run Flutter Flavorizr

Side note: this tool works better on a new and clean Flutter project. Since some processors reference some existing files and a specific base structure, it could be possible that running Flutter Flavorizr over an existing project could throw errors.

Before running Flutter Flavorizr, you must install the following software:

• Ruby
• Gem
• Xcodeproj (through RubyGems)

These prerequisites are needed to manipulate the iOS project and schemes. If you are interested in flavorizing Android only, you can skip this step. Keep in mind that you will have to use a custom instructions set with Android and Flutter processors only, otherwise an error will occur.

This package is intended to support development of Dart projects. In general, put it under dev_dependencies, in your pubspec.yaml:

dev_dependencies:
  flutter_flavorizr: ^1.0.2

You can install packages from the command line:

pub get

Once all of the prerequisites have been installed and you have added flutter_flavorizr as a dev dependency, you have to edit your pubspec.yaml and define the flavors.

Add a new key named flavorizr and define two sub-items: app and flavors. Under the flavors array you can define the name of the flavors, in our example apple and banana. For each flavor you have to specify the app name, the applicationId and the bundleId.

flavorizr:
  app:
    android:
      flavorDimensions: "flavor-type"
    ios:

  flavors:
    apple:
      app:
        name: "Apple App"

      android:
        applicationId: "com.example.apple"

      ios:
        bundleId: "com.example.apple"

    banana:
      app:
        name: "Banana App"

      android:
        applicationId: "com.example.banana"
      ios:
        bundleId: "com.example.banana"

When you finished defining the flavorizr configuration, you can proceed by running the script with:

flutter pub run flutter_flavorizr

Once the process has generated the flavors, you can run them by typing

flutter run --flavor <flavorName> -t lib/main-<flavorName>.dart

Example

flutter run --flavor apple -t lib/main-apple.dart
flutter run --flavor banana -t lib/main-banana.dart

• Let the user define its custom set of available instructions.
• Create Firebase processors.
• Use a groovy parser to better manipulate the build.gradle file
