Fix UnknownHostException

✅ Solution

UnknownHostException in firebase-auth usually indicates a DNS resolution problem, meaning your application can't translate the Firebase server's hostname into an IP address. Ensure your device or emulator has a stable internet connection and that your network allows DNS lookups. You can also try switching to a public DNS server (like Google's 8.8.8.8) in your network settings to resolve potential DNS server issues.
