我不知道我收到此错误的确切原因，但每隔 3 秒，我的调试日志中就会出现访问隐藏方法错误。如何检查执行此访问的功能以及为什么？这是真正的问题吗？我应该避免这种情况吗？

The bad news is taking a cursory look seems to show that it's not aFlutter issue but a general Android issue with how Android protobufsare using hidden APIs.

It's been fixed on Android 11 inhttps://android-review.googlesource.com/c/platform/art/+/1294616/ butunfortunately is unlikely to be backported to older Android versions.A more likely scenario is plugins updating to newer transitiveversions of protobufs. There isn't much we can do in Flutter. Usingthe IDE to hide those messages in the output is a reasonableworkaround in the meantime such as #27095 (comment).

Internal issue b/154851649. External protobuf issueprotocolbuffers/protobuf#7337.
