## Getting Started
Let's start by setting up our environment in order to run Flutter
Flavorizr
### Prerequisites
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](https://www.ruby-lang.org/en/documentation/installation/)
* [Gem](https://rubygems.org/pages/download)
* [Xcodeproj](https://github.com/CocoaPods/Xcodeproj) (through RubyGems)
These prerequisites are needed to manipulate the iOS and macOS projects and
schemes. If you are interested in flavorizing Android only, you can skip
this step.
If your app uses a Flutter plugin and you plan to create flavors for iOS and macOS, you need to make
sure there's an existing Podfile file under the ios/macos folder. This might lead to problems like
["Unable to load contents of file list"](doc%2Ftroubleshooting%2Funable-to-load-contents-of-file-list%2FREADME.md).
### Installation
This package is intended to support development of Flutter projects. In
general, put it under
[dev_dependencies](https://dart.dev/tools/pub/dependencies#dev-dependencies),
in your [pubspec.yaml](https://dart.dev/tools/pub/pubspec):
```yaml
dev_dependencies:
flutter_flavorizr: ^2.2.3
```
You can install packages from the command line:
```terminal
pub get
```
## Create your flavors
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](https://dart.dev/tools/pub/pubspec) and define the
flavors.
### Example
Create a new file named flavorizr.yaml and 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*.
```yaml
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"
```
Alternatively, add a new key named flavorizr and define a sub item named *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*.
This way of defining flavors will be deprecated in versions 3.x
```yaml
flavorizr:
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"
```

```
#### customConfig (for Android only)
You can define any custom property for android
```yml
flavors:
apple:
app:
name: "Apple App"
android:
applicationId: "com.example.apple"
customConfig:
versionNameSuffix: "\"-green-prod\"" # Don't forget to escape strings with \"
signingConfig: flavorSigning.green
versionCode: 1000
minSdkVersion: 23
# ..... and any custom property you want to add
```
This .yml part, generate this custom android flavor:
```groovy
apple {
dimension "flavor-type"
applicationId "com.example.apple"
versionNameSuffix "-green-prod"
signingConfig flavorSigning.green
versionCode 1000
minSdkVersion 23
}
```
#### adaptiveIcon (for Android only)
You can define adaptiveIcon for android:
```yml
flavors:
apple:
app:
name: "Apple App"
android:
applicationId: "com.example.apple"
icon: "assets/icon/appleApp/ic_launcher.png"
adaptiveIcon:
foreground: "assets/adaptive_icon/appleApp/ic_launcher_foreground.png"
background: "assets/adaptive_icon/appleApp/ic_launcher_background.png"
```
After removing adaptiveIcon key, the adaptive icons generated before will still exist. Please delete adaptiveIcon manually.
## Usage
When you finished defining the flavorizr configuration, you can proceed by running the script with:
```terminal
flutter pub run flutter_flavorizr
```
You can also run flutter_flavorizr with a custom set of processors by appending the -p (or --processors) param followed by the processor names separated by comma:
```terminal
flutter pub run flutter_flavorizr -p ,
```
Example
```terminal
flutter pub run flutter_flavorizr -p assets:download
flutter pub run flutter_flavorizr -p assets:download,assets:extract
```
## Run your flavors
Once the process has generated the flavors, you can run them by typing
```terminal
flutter run --flavor -t lib/main_.dart
```
Example
```terminal
flutter run --flavor apple -t lib/main_apple.dart
flutter run --flavor banana -t lib/main_banana.dart
```
Currently, due to a bug in the Flutter SDK, it's not possible to run the macOS flavors from the terminal.
You can run them from XCode by selecting the proper schema and by pressing play.
### Default processors set
By default, when you do not specify a custom set of processors by appending the -p (or --processors) param, a default processors set will be used:
* assets:download
* assets:extract
* android:androidManifest
* android:buildGradle
* android:dummyAssets
* android:icons
* flutter:flavors
* flutter:app
* flutter:pages
* flutter:main
* flutter:targets
* ios:podfile
* ios:xcconfig
* ios:buildTargets
* ios:schema
* ios:dummyAssets
* ios:icons
* ios:plist
* ios:launchScreen
* macos:podfile
* macos:xcconfig
* macos:configs
* macos:buildTargets
* macos:schema
* macos:dummyAssets
* macos:icons
* macos:plist
* google:firebase
* huawei:agconnect
* assets:clean
* ide:config
## Customize your app
Flutter_flavorizr creates different dart files in the lib folder. In the
flavors.dart file we have the F class which contains all of our
customizations.
```dart
class F {
static Flavor? appFlavor;
static String get title {
switch (appFlavor) {
case Flavor.apple:
return 'Apple App';
case Flavor.banana:
return 'Banana App';
default:
return 'title';
}
}
}
```
The process creates a simple title customization: a
switch which checks the current appFlavor (defined in our app starting
point) and returns the correct value. Here you can write whatever you
want, you can create your custom app color palette, differentiate the
URL action of a button, and so on.
If you are wondering how to use these
getters, you can find an example under the pages folder: in the
my_home_page.dart file, the page shown after the launch of the app, we
can see a clear reference on the title getter defined in the F class.
## Side notes
I haven't found yet a good groovy parser to guarantee the idempotency of the AndroidBuildGradleProcessor.
The only way to keep track of the autogenerated flavorDimensions is to mark up the beginning and the end of the section with magic comments.
Please do not erase these comments otherwise you will break down the AndroidBuildGradleProcessor.
## Third party services
### Google Firebase
In order to flavorize your project and enable Firebase in your flavor you have to define a firebase object below each OS flavor. Under the firebase object you must define the config path of the google-services.json (if you are under Android configuration) or GoogleService-Info.plist (if you are under iOS or macOS configuration).
As you can see in the example below, we added the path accordingly
```yaml
flavors:
apple:
app:
name: "Apple App"
android:
applicationId: "com.example.apple"
firebase:
config: ".firebase/apple/google-services.json"
ios:
bundleId: "com.example.apple"
firebase:
config: ".firebase/apple/GoogleService-Info.plist"
banana:
app:
name: "Banana App"
android:
applicationId: "com.example.banana"
firebase:
config: ".firebase/banana/google-services.json"
ios:
bundleId: "com.example.banana"
firebase:
config: ".firebase/banana/GoogleService-Info.plist"
```
### Huawei AppGallery Connect
In order to flavorize your project and enable AppGallery Connect in your flavor
you have to define an agconnect object below each Android flavor. Under the agconnect object you must define the config path of the agconnect-services.json.
As you can see in the example below, we added the path accordingly
```yaml
flavors:
apple:
app:
name: "Apple App"
android:
applicationId: "com.example.apple"
agconnect:
config: ".agconnect/apple/agconnect-services.json"
ios:
bundleId: "com.example.apple"
banana:
app:
name: "Banana App"
android:
applicationId: "com.example.banana"
agconnect:
config: ".agconnect/banana/agconnect-services.json"
ios:
bundleId: "com.example.banana"
```
