android - 在 intellij 中运行示例 dart 应用程序时发生错误

Question

我正在尝试在 Intelij IDE 中运行我的第一个示例颤振应用程序，但我收到一个无法解决的错误。

我所做的是，文件 > 新建 > 项目，然后我选择颤振，并给出应用程序名称，然后单击确定。

接下来当界面加载时，我连接了我的手机，然后我看到它显示在右上角，在它旁边我选择了 main.dart 并按下了绿色的播放按钮，但是在控制台中我得到了一个错误。

BUILD FAILED in 30s
Finished with error: Gradle task assembleProfile failed with exit code 

我的 build.gradle 文件：

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

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

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

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

这是我的 build.gradle 文件。我看到，当我将鼠标悬停在 buildscript 上时，intellij 说，无法解析符号“buildscript”，对于其他定义（例如此文件中的存储库）也会发生同样的情况。
