Kotlin and Android Development featuring Jetpack:
There is an error when following steps to use the nav_version variable in project’s build.gradle of Penny_Drop.
Following the official documentation the way to use this variable is adding in the app’s build.gradle file: https://developer.android.com/guide/navigation/navigation-getting-started
dependencies {
def nav_version = "2.3.5"
implementation "androidx.navigation:navigation-fragment:$nav_version"
implementation "androidx.navigation:navigation-ui:$nav_version"
.......
}
