A config plugin that allows customizing native build properties during prebuild.
expo-build-properties
is a config plugin configuring the native build properties
of your android/gradle.properties and ios/Podfile.properties.json directories during Prebuild.
This config plugin configures how Prebuild command generates the native android and ios folders and therefore cannot be used with projects that don't runnpx expo prebuild
(bare projects).
