When building a regular Android app with Gradle, I can add params as such:
./gradlew assembleRelease -Pusername=foo -Ppassword=bar
With Flutter, this is what I'm supposed to call in order to assemble an APK:
flutter build apk
How do I pass the params to Gradle in this case?
P.S. I'm trying to use Jenkins credentials in a pipeline configuration. I do not want to expose my password, so avoiding using the arguments and putting it directly into the project is not an option.
You can pass variables via the environment, I use this method with Jenkins. The job can be configured to pass the credentials via environment variables.
In your build.gradle (where needed):
username = System.getenv('SECRET_USERNAME')
password = System.getenv('SECRET_PASSWORD')
Please notice that System.getenv(...) returns null if the variable is not defined.
In your development environment you should export the variables:
$ export SECRET_USERNAME="my secret username"
$ export SECRET_PASSWORD="my super secret password"
Please, I do not know which IDE are you using, but both IntelliJ and AndroidStudio do support declaring environment variables.
You can set project properties through environment variables like ORG_GRADLE_PROJECT_foo=bar, so that you don't have to modify the gradle scripts, for example:
export ORG_GRADLE_PROJECT_username=foo
export ORG_GRADLE_PROJECT_password=bar
flutter build apk
