On Linux, problems building an Android app that uses flavor dimensions with uppercase characters #24106
Description
Happening on latest beta ([✓] Flutter (Channel master, v0.10.3-pre.145, on Mac OS X 10.13.6 17G3025, locale en-US))
I have a Flutter app that uses the following flavor dimensions scheme (Gradle):
flavorDimensions "brand", "region"
productFlavors {
BRAND1 {
dimension "brand"
applicationIdSuffix ".brand1"
}
BRAND2 {
dimension "brand"
applicationIdSuffix ".brand2"
}
northAmerica {
dimension "region"
applicationIdSuffix ".northamerica"
}
spain {
dimension "region"
applicationIdSuffix ".spain"
}
}When running the app, this is the run command that I use:
flutter run -t lib/main/main_brand1_north_america_debug.dart --flavor BRAND1NorthAmerica
While this works perfectly on iOS, on Android I get the following error:
➜ git:(master) flutter run -t lib/main/main_brand1_north_america_debug.dart --flavor BRAND1NorthAmerica
Using hardware rendering with device Android SDK built for x86. If you get graphics artifacts, consider enabling software rendering with "--enable-software-rendering".

The Gradle project does not define a task suitable for the requested build.
The android/app/build.gradle file defines product flavors: brand1, brand1spain, brand1northamerica, brand2, brand2spain, brand2northamerica
You must specify a --flavor option to select one of them.
Gradle build aborted.
As you can see, there's a problem where the product flavors are lowercased, but those do not match the gradle tasks available.
If I follow the recommendation of the error message and try to lowercase the flavor, it still fails:
➜ mobile_connected git:(master) flutter run -t lib/main/main_brand1_north_america_debug.dart --flavor brand1northamerica

Gradle build failed to produce an Android package.
And it is because that gradle task does not exist.
