创建项目
最简单的命令只要 flutter create my_flutter_app 即可。注意 flutter 建议使用使用这样命名方式。
关于 创建项目的更多选项参考: flutter help create
如果出现类似下面的错误，多试几次。
➜ ~flutter create -t app --org=banxi1988.com -i swift -a kotlin try_flutter_app

please let us know at https://github.com/flutter/flutter/issues.
后面可能会遇到：
Running "flutter packages get" in try_flutter_app...
Connection failed (OS Error: No route to host, errno = 65), address = storage.googleapis.com, port = 443
这个时候可以考虑使用国内的镜象。下面是我们的环境变量配置:
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
设置好镜象之后可以运行其他命令如 flutter run 或者 flutter packages get
来下载依赖。
下面是一次成功的运行过程输出：

一般可以说是分为临时的和非临时的。
像上面的介绍的应该是配置成非临时的。 也就是你所说的电脑系统的环境变量。
但是说明的是，我上面的示例是针对 Unix类系统的。
你可能需要先搜索配置一下 Gradle 环境。
Gradle 素来在国内是比较慢的。
