Flutter新建项目运行报错，错误如下

这个问题是Google被墙了，需要配置阿里云镜像

第一步：修改android目录下的build.gradle文件中的

buildscript { ext.kotlin_version = '1.3.50' 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:3.5.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" } } 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'} } }

第二步：修改flutter sdk下的flutter.gradle文件，具体目录是flutter\packages\flutter_tools\gradle

buildscript { repositories { 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' } } dependencies { classpath 'com.android.tools.build:gradle:3.5.0' } }
