找不到方法颤振（）

Question

我正在尝试在 macos 上的 android 模拟器中打开我的应用程序，但出现以下错误

* Where:
Build file '/Users/home/app_sources/my_app/android/app/build.gradle' line: 63

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not find method flutter() for arguments [build_enl1wb3rxbgojqnsmrkb1pqib$_run_closure3@4a124cf3] on project ':app' of type org.gradle.api.Project.

另外，如果我尝试Open Android module in Android Studio

打开时没有配置

当我尝试添加配置时，没有模块到 select

过去 3 天我一直面临这个问题，相信我，我已经尝试了这个网站上的每个主题，关于这个问题的每一篇文章都没有任何效果，所以请不要建议谷歌搜索，因为我已经做了很多！

笔记：

1. 使用Sync Project with Gradle Files返回与上述相同的错误
2. 使用Invalidate Caches也无济于事。
3. 注释在settings.gradle中include ':app'并同步，再次取消注释和同步也无济于事。

任何想法？

更新

settings.gradle

include ':app'

def properties = new Properties()

assert localPropertiesFile.exists()
localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }

Answer 1

您需要更新 build.gradle

def localPropertiesFile = rootProject.file('local.properties')

至

def localPropertiesFile = new rootProject.file('local.properties')

将解决您的 r 问题。

Answer 2

解决了

我已经删除Flutter SDK和Dart SDK然后从错误中消失。

PS：我不知道为什么会发生这种情况，也不知道为什么全新安装解决了这个问题（特别是我安装的版本与这个全新安装的版本相同）但它成功了，这就是我所知道的。

Answer 3

我删除了新的，一切都很好

android/app/build.gradle

throw new GradleException（“未找到颤振 SDK。在 local.properties 文件中使用 flutter.sdk 定义位置。”）
