通过函数计算的Custom Runtime，您可以使用Dart在函数计算平台编写函数。本文介绍快速部署和调用Dart函数的详细步骤。您可以按需修改Dart示例中的代码实现二次开发。
操作步骤
- 执行以下命令，初始化项目。
s init fc-custom-dart-event -d fc-custom-dart-event
- 执行以下命令，进入项目目录。
- 可选：按需修改函数的示例代码，实现二次开发。
- 执行以下命令，部署项目。
s deploy -y

Tips for next step
======================
* Display information of the deployed resource: s info
* Display metrics: s metrics
* Display logs: s logs
* Invoke remote function: s invoke
* Remove Service: s remove service
* Remove Function: s remove function
* Remove Trigger: s remove trigger
* Remove CustomDomain: s remove domain
