Flutter包已下載解壓縮，接下來(lái)更新環(huán)境變量。 （Mac OS系統(tǒng)）
cd $HOME
vim ~/.bash_profile
在打開(kāi)的頁(yè)面添加上下面代碼
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cnexport
PATH=/Users/xxx/Documents/flutter/bin:$PATH? ? ? ?//Flutter SDK的目錄
配置完成后，再調(diào)用下面命令使之生效。下次無(wú)論在哪打開(kāi)shell都可以使用flutter命令；
source ~/.bash_profile
注意：現(xiàn)配置完后每次重新打開(kāi)終端都要重新source ~/.bash_profile才可以正常使用flutter命令
這個(gè)時(shí)候就可以使用flutter命令了，現(xiàn)在打開(kāi)終端，運(yùn)行：
flutter -h
正常的話就會(huì)出來(lái)flutter的命令幫助簡(jiǎn)介。
2、通過(guò)運(yùn)行flutter/bin命令驗(yàn)證目錄是否在已經(jīng)在PATH中:
?echo $PATH
/Users/xxx/Documents/flutter/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Users/hst/.rvm/bin:/Users/hst/.rvm/bin
有包含flutter/bin說(shuō)明環(huán)境變量設(shè)置成功！
接下來(lái)創(chuàng)建第一個(gè)Flutter App
cd到要?jiǎng)?chuàng)建到目錄下，

In order to run your application, type:
? $ cd myapp
? $ flutter run
To enable null safety, type:
? $ cd myapp
? $ dart migrate --apply-changes
Your application code is in myapp/lib/main.dart.
看到底下這幾行，說(shuō)明已經(jīng)成功創(chuàng)建Flutter App了。
打卡項(xiàng)目底下的ios/Runner.xcworkspace，運(yùn)行到模擬器，可以看到如下效果了：
