A powerful runtime to build AWS Lambda functions in Dart with native AWS events. Sound null safety.

Dart Runtime for AWS Lambda (Sound Null Safety)

A 🎯 Dart Runtime for ƛ AWS Lambda

---

This package is based on the official aws-lambda-dart-runtime. It is a restructured version of the outdated official aws-lambda-dart-runtime adapted to the latest Dart SDK to make it easier to maintain.

Thanks to katallaxie and AWS Labs involved in the development of the original stuff!

You can read the official document too!
