Flutter - 在 Android 上访问隐藏方法 Lsun/misc/Unsafe 错误

Question

我收到一个 Flutter 项目的错误。我将开始一个一个地停用插件，并希望找出其中一个是否导致了问题。在那之前，如果有人有建议，我会留在这里。

使用 Android Studio 打开 Android 应用程序显示以下通知：

Compilation is not supported for following modules: cloud_firestore, cloud_firestore_web, firebase_auth, 
firebase_core, firebase_auth_web, firebase_core_web, google_maps_flutter, flutter_plugin_android_lifecycle, 
google_sign_in, google_sign_in_web, 
location. 
Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project.

根据 Flutter 团队的回复，这是一个 Android protobuf 问题：https://github.com/flutter/flutter/issues/27095#issuecomment-722857855。

它已在 Android 11 中修复：https://android-review.googlesource.com/c/platform/art/+/1294616/。
