二、 解决方案

在 Flutter 工程下的 android/build.gradle 下进行如下配置 :

在 repositories 配置如下源 : 注释掉 google() 和 jcenter() , 并添加如下代码 , 其它配置不用动 ;

maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
maven { url "http://download.flutter.io" }

完整代码如下 :

buildscript {
    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
        maven { url "http://download.flutter.io" }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
    }
}

allprojects {
    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
        maven { url "http://download.flutter.io" }
    }
}

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

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

使用上述方案已解决问题 ;

三、 备选方案

( 该方案没有经过测试 )

在 flutter\packages\flutter_tools\gradle\resolve_dependencies.gradle 中 ,

添加如下代码 :

maven {
    url 'http://download.flutter.io'
}

注意添加位置 :

repositories 添加后的配置 :

repositories {
    google()
    jcenter()
    maven {
        url "$storageUrl/download.flutter.io"
    }
	maven {
        url 'http://download.flutter.io'
    }
}
