Hi Team:

The existing Flutter Maven repository: http://download.flutter.io or https://storage.googleapis.com/download.flutter.io couldn't be easily accessed in China now. I was wondering if there's any chance to migrate this Flutter Maven repository to google() since the maven.google.com is working for China, or using the FLUTTER_STORAGE_BASE_URL for instead?

Thanks to @liudonghua123 for giving this feedback.
