在尝试编译一个应用，甚至在升级Flutter本身时，我看到这个错误：

Failed to decode advisories for archive from https://pub.dev.

FormatException: advisoriesUpdated must be a String

package:pub/src/source/hosted.dart 670               HostedSource.\_extractAdvisoryDetailsForPackage

package:pub/src/source/hosted.dart 622               HostedSource.\_fetchAdvisories

===== asynchronous gap ===========================

package:pub/src/source/hosted.dart 839               HostedSource.\_getAdvisories

===== asynchronous gap ===========================

package:pub/src/source/hosted.dart 1120              HostedSource.getAdvisoriesForPackageVersion

===== asynchronous gap ===========================

package:pub/src/solver/report.dart 425               SolveReport.\_reportPackage

解决方案

可能值得关注这个问题，但总体看来似乎没有机制能够避免这次失败
