A powerful runtime to build Lambda functions in Dart with native AWS events. Sound null safety.
APACHE-2.0 License
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 It is a restructured version of the outdated official aws-lambda-dart-runtime adapted to the latest Dart SDK to make it easier to maintain.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!
