I am installing react-native-maps. In the installation guide, on Build configuration on Android in Section 3.1, it shows:
buildscript {
    ext {
        buildToolsVersion = "xxx"
        minSdkVersion = xxx
        compileSdkVersion = xxx
        targetSdkVersion = xxx
        supportLibVersion = "xxx"
        playServicesVersion = "xxx" // or set latest version
        androidMapsUtilsVersion = "xxx"
    }
}
...
How can i get  supportLibVersion , playServicesVersion  and androidMapsUtilsVersion values?
