应用运行时出现错误“$flutterSdkpath\packages\flutter_tools\gradle\app_plugin_loader.gradle”

Question

我在运行安装应用程序时遇到问题。我的 flutter 详细信息是：

Flutter 版本：1.12.13+hotfilx.9

Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.12.13+hotfix.9, on Microsoft Windows [Version 10.0.17763.1098], locale en-IN)

运行在 visual studio 中运行抖动时显示如下：

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

FAILURE: Build failed with an exception.

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

* What went wrong:
A problem occurred evaluating settings 'android'.
> Could not read script '\flutter\packages\flutter_tools\gradle\app_plugin_loader.gradle' as it does not exist.

在此先感谢您对我的帮助。

Answer 1

在主频道上创建的 Flutter 项目将生成一个 android/settings.gradle 文件，该文件指向 1.18.0-dev.5.0 (currently available on all channels) 中存在的 Flutter 工具中的一个文件。

从 master 切换到 stable 相对于该更改“降级”Flutter，文件不再存在。

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

$ rm android/settings.gradle
$ flutter create .

有关详细信息，请参阅 GitHub issue。

Answer 2

只需将当前setting.gradle文件代码替换为你想要的运行版本项目setting.gradle。例如：其他版本项目： android>setting.gradle

此代码将是您当前的 flutter 版本，只需将您的 setting.gradle 替换为旧项目或其他项目

Settings.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
}

Answer 3

只需降级最近使用的library/package就可以了

Answer 4

将频道从 stable 更改为 master 对我有用。

查看频道：

flutter channel

要更改频道：

flutter channel <channel_name>

例如flutter channel master

Answer 5

只需转到路径 sdk flutter 路径

$flutterPath\packages\flutter_tools\gradle\app_plugin_loader.gradle

并确保文件 app_plugin_loader 存在，如果不存在则从回收站恢复它或下载它
