1)、第一处修改：
google()
mavenCentral()
改为:
maven { url 'https://maven.aliyun.com/repository/central' }
maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/public'}

url "$storageUrl/${engineRealm}download.flutter.io"
改为：url "https://mirrors.tuna.tsinghua.edu.cn/flutter/download.flutter.io"
2. 找到Flutter SDK目录下的Flutter配置文件flutter.groovy
地址为： flutter/packages/flutter_tools/gradle/src/main/groovy
1）、第一处修改

mavenCentral()
改为:
maven { url 'https://maven.aliyun.com/repository/central' }
maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/public'}
2）、第二处修改
DEFAULT_MAVEN_HOST = "https://storage.googleapis.com";
改为：DEFAULT_MAVEN_HOST = "https://mirrors.tuna.tsinghua.edu.cn/flutter"
3.修改项目根目录下Android/build.gradle文件镜像地址
google()
mavenCentral()
改为:
maven { url 'https://maven.aliyun.com/repository/central' }
maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/public'}
4.修改项目gradle下载地址
路径：项目根目录/android/gradle/wrapper/gradle-wrapper.properties
