Android managing the activity or inactivity of a function in build gradle in fastlane

I am managing the activity or inactivity of a function in build gradle in fastlane.

Because when sending a version from fastlane, this function prevents compiling for other applications.

if (project.rootProject.file('dev.props').exists()){
    def devProps = new Properties()
    devProps.load(project.rootProject.file('dev.props').newDataInputStream())
    def currentDevFlavor = devProps.DEV_FLAVOR

    android.variantFilter { variant ->
        def flavorName = variant.getFlavors().get(0).name
        if(currentDevFlavor  && flavorName != currentDevFlavor) {
            variant.setIgnore(true)
        }
    }
}

Is there a way to do this?

sorry for my English level
