Answer 1

试试这个：请按照以下步骤操作：

转到 flutter_app => android => gradle => 包装器目录

删除 gradle-wrapper.jar 文件

打开并编辑 gradle-wrapper.properties 文件

将 distributionUrl=https://services.gradle.org/distributions/gradle-xxx-all.zip 更改为 gradle-5.6.2-all.zip 或最新版本

在终端上使用 flutter run 命令

Answer 2

是的，我也有同样的问题，这可能是由于您的 Gradel 文件损坏了，所以请尝试以下对我有用的步骤，

去，

C->user->(username)->.gradle 删除 .gradle 文件并运行然后运行您的 flutter 项目，一旦重新运行您的项目，它将正确创建新的 .gradle 文件夹，

希望它会起作用...
