@maureenorea-clores we need to add buildFeatures.buildConfig = true also in the config/android/android.gradle inside the android{...} DSL block.

Since, we are using buildConfigField("String","VERSION_NAME", "\"$project.version\"") , without that there shall be following error

A problem occurred configuring project ':xxxx'.
defaultConfig contains custom BuildConfig fields, but the feature is disabled.
To enable the feature, add the following to your module-level build.gradle:
android.buildFeatures.buildConfig = true

what is the objective of adding this block here ?
What is the issue if we don't have it i.e. why do we need it ?
