在 Visual Studio 中运行 flutter run 时，它显示以下内容：

Launching lib\main.dart on CPH1859 in debug mode...

Settings file 'project_name\android\settings.gradle' line: 15

预先感谢您对我的帮助。

Answer 1

在主通道上创建的 Flutter 项目将生成一个android/settings.gradle文件，该文件指向 1.18.0-dev.5.0 中存在的 Flutter 工具中的文件（目前在所有通道上可用）。

从 master 切换 -> 稳定“降级” Flutter 相对于该更改，并且该文件不再存在。

您可以通过android/settings.gradle在稳定状态下重新生成您的时间来解决此问题：

$ rm android/settings.gradle
$ flutter create .

只需将当前 setting.gradle 文件代码替换为您想要运行的版本项目 setting.gradle。例如：其他版本项目：android>setting.gradle

此代码将是您当前的颤振版本，只需将您的 setting.gradle 替换为旧的或其他项目

设置.gradle

include ':app' 

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
   pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
   def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
   include ":$name"
   project(":$name").projectDir = pluginDirectory
}
