Gradle 同步失败：原因：assert pluginDirectory.exists()

Question

我在标题和下面放置了错误。当您在文件夹 /android 上打开 Android Studio 时，会发生该错误。我的项目是Flutter项目。我使用 Samsung Galaxy A10 上的Android 应用程序Max 2D Game创建了我的项目。

Gradle sync failed: Cause: assert pluginDirectory.exists()
                            |               |
                            |               false               > 
                           \root\snap\flutter\common\flutter\.pub-cache\hosted\pub.dartlang.org\audioplayers-0.15.1\android 

我邀请您在Gitpod上探索我的项目或在GitHub上 fork并提交修复此错误的拉取请求。

在 android/app 文件夹中打开 android studio 时出现以下错误：

Answer 1

assert pluginDirectory.exists()正在返回错误，因为您pub cache不知何故失去了同步。

在这种情况下，请使用命令

flutter pub get

从根文件夹中删除，以便将所有依赖项与缓存重新同步。
