Fix `GoogleSignInException`

in Flutter

✅ Solution

The "GoogleSignInException" often arises from misconfiguration in your Firebase project or incorrect SHA keys/bundle IDs. Ensure your Firebase project has the correct SHA-1 and SHA-256 keys for your Android app and the correct bundle ID for your iOS app, downloaded the updated google-services.json/GoogleService-Info.plist, and properly configured OAuth 2.0 client IDs. Rebuilding your app after these corrections is crucial for the changes to take effect.
