<version>：直接点击https://dart.dev，官网首页里最上面就有最新的稳定版本直接填进去就可了
例如Mac：https://storage.googleapis.com/dart-archive/channels/stable/release/2.8.2/sdk/dartsdk-macos-x64-release.zip

https://storage.googleapis.com/dart-archive/channels/<stable|beta|dev>/release/<version>/sdk/dartsdk-<platform>-<architecture>-release.zip

根据不同平台选择即可下载

https://storage.googleapis.com/dart-archive/channels/stable/release/2.1.1/sdk/dartsdk-macos-x64-release.zip

下载完之后，
到~/.bash_file目录下
将下面填入，将/Users/damo/dart-sdk/bin换成你自己dart-sdk的目录

export DART_HOME=/Users/damo/dart-sdk/bin
export PATH="${DART_HOME}:${PATH}"

之后保存执行
