试图构建应用程序，编译器输出如下：

我尝试删除 app_settins 插件，但它在另一个插件上失败了，所以我认为这是一个普遍问题，而不是特定于插件的问题。

我尝试重新安装不同版本的AndroidStudio，就像jdk和flutter sdk一样

我就是想不通

帮助！

这是 build.gradle：

buildscript {
    ext.kotlin_version = '1.4.31'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这可能是侥幸，但我在网上搜索时偶然发现了this！

有点追随它，我删除了所有缓存的插件 user_folder>/AppData/Local/Pub/Cache/hosted/pub.dartlang.org/ 然后在项目中运行flutter pub get。

现在可以了。

如果有人知道为什么/如何工作，请解释一下，谢谢！
