The new Dart Signature V4 client allows developers to securely integrate with all 200+ AWS services using signed HTTP requests. This functionality enables Dart developers to make native calls to AWS backends in their Flutter or Dart applications, to make changes to the data or configurations of AWS services.

Developers can add the Signature V4 client as a dependency to their Flutter or dart application, and use it to interact with AWS services. For example, using the Dart Signature V4 client, a developer can interact with the Amazon Simple Storage Service (Amazon S3) using signed HTTP requests to create a new S3 Bucket. Developers can then choose to upload files to their S3 buckets and also manage the read/write permissions for the files within these buckets.
