flutter小记

一、环境安装

• windows安装

• macos安装 ** mac永久生效的环境变量配置

• 设置国内源,类似我们平时用npm会给它源设置成淘宝源

  打开.zhsrc

  open ~/.zhsrc
  

  在.zhsrc中添加如下代码

  export PUB_HOSTED_URL=https://pub.flutter-io.cn
  export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
  

  重新加载.zhsrc

  source ~/.zhsrc
  

二、编辑器安装 android studio

• android studio安装教程
• 安装flutter插件 settings->plugins 搜索flutter install完成后设置插件flutter路径：/你的flutter安包路径/flutter
• 安装dart插件 settings->plugins 搜索dart install完成后设置插件dart路径：/你的flutter安包路径/flutter/bin/cache/dart-sdk/bin
• 运行安卓虚拟机
• 运行 flutter doctor命令看看还有啥报错，解决对应的报错，xcode错误可忽略

运行flutter项目

• 安装依赖

    flutter pub get

• 依赖装好后运行

可能会运行的很慢，且报错： Could not resolve all artifacts for configuration 'classpath'。相关解决可查看

• 强烈建议更改如下文件

1.flutter项目android目录下的build.gradle文件,将 google() ；jcenter()；注释，更换源如下

buildscript { 
   repositories { 
     // google() 
     // jcenter() 
     maven { url 'https://maven.aliyun.com/repository/google' } 
     maven { url 'https://maven.aliyun.com/repository/jcenter' } 
     maven { url 'https://maven.aliyun.com/nexus/content/groups/public'} 
   } 
   dependencies { 
     classpath 'com.android.tools.build:gradle:3.1.2' } 
   } 
   allprojects { 
      repositories { 
        // google() 
        // jcenter() 
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' } 
   } 
}

2.修改flutter.gradle文件,位置在你的flutter包-->packages-->flutter_tools-->gradle 将 google() ；jcenter()；注释。更换源如下

 maven { url 'https://maven.aliyun.com/repository/google' } 
 maven { url 'https://maven.aliyun.com/repository/jcenter' } 
 maven { url 'https://maven.aliyun.com/nexus/content/groups/public'}
