我在尝试访问存储在cloud firestore中的数据时遇到了一个问题，因为我知道firebase身份验证工作得很好。调试控制台给我这个消息

我使用的是三星galaxy A50安卓10。
坏消息是，粗略地看一下似乎表明这不是Flutter问题，而是安卓protobufs如何使用隐藏API的一般安卓问题。
它已在安卓11上修复https://android-review.googlesource.com/c/platform/art/+/1294616/但是不幸的是，它不太可能被后移植到旧的Android版本。更可能的情况是插件更新为更新的可传递插件protobufs的版本。在Flutter我们没什么可做的。使用在输出中隐藏这些消息的IDE是合理的在此期间的变通方法，如#27095(注释(。
内部问题b/154851649。外部protobuf问题protocolbuffers/protobuf#7337.
