You can use the custom runtime of Function Compute to write functions in Dart. This
topic describes how to quickly deploy and call a Dart function. You can modify the
Dart code.
Prerequisites
You have installed Node.js 8.6.0 or later. For more information, see the
official download page.
Step 1: Prepare the environment

Step 2: Deploy and call a function
- Run the following command to clone the sample project to your local device.
git clone https://github.com/awesome-fc/fc-custom-demo
- Optional:Modify the sample code in the dart-demo directory to implement your business logic.
- Run the following command to access the cloned sample project:
cd fc-custom-demo
cd dart-demo
- Run the following command to deploy the project to Function Compute:
The following results are returned:
Waiting for service dart-demo to be deployed...
Waiting for function dart-func to be deployed...
Waiting for packaging function dart-func code...
The function dart-func has been packaged. A total of 2 files were compressed and the final size was 2.57 MB
function dart-func deploy success
service dart-demo deploy success
- Run the following command to call the deployed function:
fun invoke -e "Hello World"
The following results are returned:
