@fisforfaheem This example is pretty old now and it looks like Netlify is reporting your build failed. I'd probably work on getting the build to work locally first and there is probably a better way to do this now. Have you read through the Flutter web docs here? https://docs.flutter.dev/platform-integration/web/building
