In my Flutter mobile app have two flavors with separate res
folders for each. I have added sourceSet
in build.gradle
file, but at runtime the running flavor does not show the relavant resource from flavor folder, instead the main
folder resources.
Folder structure as below.
src
|
flavor1
------res(with sub folders)
|
flavor2
------res(with sub folders)
|
main
------res(with sub folders)
build.gradle
file changes.
android {
sourceSets {
main {
java.srcDirs += 'src/main/kotlin'
res.srcDirs = ['src/main/res']
manifest.srcFile 'src/main/AndroidManifest.xml'
}
flavor1 {
res.srcDirs = [
'src/flavor1/res/drawable-hdpi',
'src/flavor1/res/drawable-ldpi',
'src/flavor1/res/drawable-mdpi',
'src/flavor1/res/drawable-v21',
'src/flavor1/res/drawable-xhdpi',
'src/flavor1/res/drawable-xxhdpi',
'src/flavor1/res/drawable-xxxhdpi',
'src/flavor1/res/drawable',
'src/flavor1/res/mipmap-hdpi',
'src/flavor1/res/mipmap-mdpi',
'src/flavor1/res/mipmap-xhdpi',
'src/flavor1/res/mipmap-xxhdpi',
'src/flavor1/res/mipmap-xxxhdpi',
'src/flavor1/res/raw',
'src/flavor1/res/values',
'src/flavor1/res'
]
manifest.srcFile 'src/flavor1/AndroidManifest.xml'
}
flavor2 {
res.srcDirs = [
'src/flavor2/res/drawable-hdpi',
'src/flavor2/res/drawable-ldpi',
'src/flavor2/res/drawable-mdpi',
'src/flavor2/res/drawable-v21',
'src/flavor2/res/drawable-xhdpi',
'src/flavor2/res/drawable-xxhdpi',
'src/flavor2/res/drawable-xxxhdpi',
'src/flavor2/res/drawable',
'src/flavor2/res/mipmap-hdpi',
'src/flavor2/res/mipmap-mdpi',
'src/flavor2/res/mipmap-xhdpi',
'src/flavor2/res/mipmap-xxhdpi',
'src/flavor2/res/mipmap-xxxhdpi',
'src/flavor2/res/raw',
'src/flavor2/res/values',
'src/flavor2/res'
]
manifest.srcFile 'src/flavor2/AndroidManifest.xml'
}
}
// Because of flavors and multiple res folders.
afterEvaluate {
android.applicationVariants.all { variant ->
tasks.named("generate${variant.name.capitalize()}ResValues")
.configure { task ->
task.outputs.upToDateWhen {false}
}
}
}
flavorDimensions "app"
productFlavors {
flavor1 {
dimension "app"
applicationIdSuffix ""
}
flavor2 {
dimension "app"
applicationIdSuffix ".flavor2"
}
}
}
Running the flavor2
app still refers to main
resources is the issue. I want the respective flavor to refer only the given flavor specific resource folder in runtime.
sourceSet in not necessary, just add product flavors within app/build.gradle
, folders structure is ok, at compilation time all resources are merged and main folder resources are overridden with flavor resources
just run next command
flutter run --flavor flavor2
