Building flutter tool...
Flutter 2.4.0-1.0.pre.181 • channel master • https://github.com/flutter/flutter.git
Framework • revision cc00e7e6bc (2 hours ago) • 2021-07-11 18:21:02 -0400

║ Welcome to Flutter! - https://flutter.dev ║
║ ║
║ The Flutter tool uses Google Analytics to anonymously report feature usage ║
║ statistics and basic crash reports. This data is used to help improve ║
║ Flutter tools over time. ║
║ ║
║ Flutter tool analytics are not sent on the very first run. To disable ║
║ reporting, type 'flutter config --no-analytics'. To display the current ║
║ setting, type 'flutter config'. If you opt out of analytics, an opt-out ║
║ event will be sent, and then no further information will be sent by the ║
║ Flutter tool. ║

║ By downloading the Flutter SDK, you agree to the Google Terms of Service. ║
║ Note: The Google Privacy Policy describes how data is handled in this ║
║ service. ║

║ Moreover, Flutter includes the Dart SDK, which may send usage metrics and ║

配置环境变量 :
压缩包下载好以后, 找个位置进行解压, 这个位置很重要, 因为下面配置环境变量的时候要用到
命令行 SDK 下载的位置
/Users/shiran/Desktop/Flutter/Flatter-Repository/FlutterSDK/flutter
- 打开终端工具 使用 vim 进行配置环境变量 命令如下 ：
$ vim ~/.bash_profile
- 在文件中写入下列代码 ：
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
- 执行命令立即生效：
source .bash_profile
解说
export PUB_HOSTED_URL=https://pub.flutter-io.cn # 国内用户需要设置
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn # 国内用户需要设置
export PATH=/Users/用户名/development/flutter/bin:$PATH # flutter的sdk路径
vi 编辑时出现 E325:ATTENTION 错误
这是由于在编辑该文件的时候异常退出了，因为 vim 在编辑文件时会创建一个交换文件 swap file 以保证文件的安全性。
- 解决办法：直接 按 D
为了去掉这个警告，我们需要删除这个 swp 文件：rm -f .config.swp
2、添加 flutter 相关工具到 path 中:
这行命令你要根据你把压缩包解压的位置来进行编写,写的是你的路径:
目前 命令行集成的使用 SDK 的方式 是：
export PATH="/Users/shiran/Desktop/Flutter/Flatter-Repository/FlutterSDK/flutter/bin:$PATH"
示例:
export PATH="/Applications/Flutter/flutter/bin:$PATH"
3、配置文件完成后，使用 source 命令重新加载一下，具体命令如下：
source ~/.bash_profile
4、使用命令检查是否安装成功，具体命令如下：
flutter --version
mac@xiaoxinxindeMac ~ % cd /Users/mac/Library/FlutterSDK
shiran@Mac FlutterSDK % source ~/.bash_profile
shiran@Mac FlutterSDK % flutter --version

5、运行以下命令查看是否需要安装其它依赖项来完成安装
$ flutter doctor
该命令检查您的环境并在终端窗口中显示报告。
Dart SDK 已经在捆绑在 Flutter 里了，没有必要单独安装 Dart。 仔细检查命令行输出以获取可能需要安装的其他软件或进一步需要执行的任务（以粗体显示）
