Flutter Flavorizr is a powerful utility designed to help developers create multiple flavors of their Flutter applications with ease. This article will guide you through the process of setting up and using Flutter Flavorizr, ensuring you can cater to different app variants without a hassle.

Getting Started

Let’s embark on our flavor adventure by setting up our environment to run Flutter Flavorizr effectively.

Prerequisites

This tool works best on a clean Flutter project. Running Flutter Flavorizr on an existing project may lead to various errors. Before proceeding, ensure you have the following software installed:

• Ruby
• Gem
• Xcodeproj (through RubyGems)

If your app uses a Flutter plugin and you plan to create flavors for iOS and macOS, ensure there is an existing Podfile under the ios/macos folder.

Installation

To install Flutter Flavorizr, add it to the dev_dependencies section of your pubspec.yaml file:

dev_dependencies:
  flutter_flavorizr: ^2.2.3

Then run the following command in your terminal:

pub get

Creating Your Flavors

After installing the prerequisites and adding flutter_flavorizr as a dependency, it’s time to define your flavors. Create a new file named flavorizr.yaml to define the flavors in your project.

flavors:
  apple:
    app:
      name: Apple App
      android:
        applicationId: com.example.apple
      ios:
        bundleId: com.example.apple
      macos:
        bundleId: com.example.apple
  banana:
    app:
      name: Banana App
      android:
        applicationId: com.example.banana
      ios:
        bundleId: com.example.banana
      macos:
        bundleId: com.example.banana

Usage

Once you’ve defined your flavor configuration, run the following command to execute the script:

flutter pub run flutter_flavorizr

You can also run with a custom set of processors by appending -p:

flutter pub run flutter_flavorizr -p processor_1,processor_2

Running Your Flavors

To run the flavors, use the command:

flutter run --flavor flavorName -t lib/main_flavorName.dart

For example:

flutter run --flavor apple -t lib/main_apple.dart

Understanding the Code: Flavors Defined in YAML

Think of defining flavors in your app like setting up a menu in a restaurant. Each flavor represents a different type of dish you serve, such as “Apple” or “Banana.” Just like you’d need to set different prices, ingredients, and cooking styles for each dish, you also define unique attributes for each flavor in the flavorizr.yaml file. This way, when a customer (or user) orders a dish (or selects a flavor), you whisk them away to a custom experience tailored just for them.

Troubleshooting

If you encounter any issues, like the error “Unable to load contents of file list,” ensure you have followed all the prerequisite requirements and that your project is freshly set up. For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
