向Flutter项目添加Flutter WebView插件时出现Gradle错误

嗨，我用flutter开发了一个应用程序，并且直到我向其中添加flutter webview插件，然后它出现此错误为止，它一直有效：

* Error running Gradle:
ProcessException: Process "C:\Users\p.mikaeil\Desktop\Files\Flutter Project\newapp\android\gradlew.bat" exited abnormally:
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project 'android'.

我尝试更改android文件夹中的gradle版本，但没有解决问题。

我该如何解决这个问题？ 感谢任何建议。

经过大量搜索和测试后，我找到了问题的解决方案：

问题是因为我的存储库不起作用。

解决问题之前，我的Project Build.gradle是这样的：

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
}

解决问题后，Project Build.gradle应该是这样的：

buildscript {
    repositories {
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        jcenter()
        maven {
            url 'https://mvnrepository.com/artifact/com.android.tools.lint/lint-gradle-api'
        }
    }

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

allprojects {
    repositories {
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        jcenter()
        maven {
            url 'https://mvnrepository.com/artifact/com.android.tools.lint/lint-gradle-api'
        }
    }
}

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

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

我也将android app build.gradle中的Compile Sdk版本和Target Sdk版本更改为28。

并且您还应该检查插件版本与android x的兼容性。

感谢这个伟大的社区。
