 🔥 修改Flutte SDK目录下的Flutter打包配置文件flutter.gradle 🔥

一般位于flutter\packages\flutter_tools\gradle\flutter.gradle

buildscript {
    repositories {
        //google()
        //mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }

    dependencies {
        /** When bumping, also update ndkVersion above, as well as the Android Gradle Plugin
         * version in ../lib/src/android/gradle_utils.dart.
         */
        classpath 'com.android.tools.build:gradle:7.3.0'
    }
}

    //此处可以配置环境变量FLUTTER_STORAGE_BASE_URL为 https://storage.flutter-io.cn来达到相同的效果
    private static final String DEFAULT_MAVEN_HOST = "https://storage.flutter-io.cn";
    //private static final String DEFAULT_MAVEN_HOST = "https://storage.googleapis.com";

    @Override
    void apply(Project project) {
        .....
        // Configure the Maven repository.
        String hostedRepository = System.env.FLUTTER_STORAGE_BASE_URL ?: DEFAULT_MAVEN_HOST
        String repository = useLocalEngine()
            ? project.property('local-engine-repo')
            : "$hostedRepository/download.flutter.io"
        rootProject.allprojects {
            repositories {
                maven {
                    url repository
                }
                //追加下面的内容
