After running Flutter run, I encountered the following error:
Failed to download https://chrome-infra-packages.appspot.com/dl/flutter/web/canvaskit_bundle/+/yrsfF-vTvu4jzBBm1o6tDl70dk y-l4G29Dnj75UvRDgC. Ensure you have network connectivity and then try again. SocketException: Operation timed out (OS Error: Operation timed out, errno = 60), address = chrome-infra-packages.appspot.com, port = 54375

Solution

1. Change to user China local mirror resources using the following command. % export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn 2. run flutter run again.
