第一步:修改项目Android目录下的build.gradle

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
//        google() 无法访问，使用阿里镜像
//        jcenter()
        maven {url 'https://maven.aliyun.com/repository/public/' }
        mavenLocal()
        mavenCentral()
    }

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

第二步:修改flutter SDK中的flutter.gradle

path: flutter\packages\flutter_tools\gradle\flutter.gradle

buildscript {
    repositories {
      maven {url 'https://maven.aliyun.com/repository/public/' }
        mavenLocal()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
    }
}
