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