1.环境变量

FLUTTER_STORAGE_BASE_URL=https://mirrors.tuna.tsinghua.edu.cn/flutter
PUB_HOSTED_URL=https://mirrors.tuna.tsinghua.edu.cn/dart-pub

2.AndroidStudio运行Android项目一直卡在Running Gradle task 'assembleDebug'...

• 项目/android/build.gradle添加阿里镜像

  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' }
  }
  
  allprojects {
      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' }
      }
  }
  

• flutter\packages\flutter_tools\gradle\flutter.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' }
      }
  }
  

启动web项目白屏问题

原因：pc端的浏览器默认使用canvaskit渲染，改成html方式就可以了

• 1.直接在终端运行命令：flutter run -d chrome --web-renderer html
• 2.AndroidStudio > 运行按钮左侧main.dart下拉选择Edit Configurations > Additional run args:后面添加--web-renderer html命令就可以了
