However, these modules also need to be compatible with your React Native version and each other. Conflicts can arise if you're using outdated versions of Expo modules or if there are compatibility issues between specific modules. Think of it as a team where each member (module) needs to work in harmony – if one member is out of sync, the whole team suffers. Your project uses several Expo modules, including expo-asset, expo-constants, expo-file-system, expo-font, expo-keep-awake, and expo-modules-core. Each of these modules has its own version and its own set of dependencies, creating a complex web of interactions. Ensuring that these modules are compatible with your React Native version and @hyperledger/indy-vdr-react-native is a crucial step in troubleshooting. We'll explore how to check the compatibility matrix of Expo modules and how to update or downgrade them to resolve conflicts.
