Lambda triggers

Amplify Flutter v1 is now in Maintenance Mode until April 30th, 2025. This means that we will continue to include updates to ensure compatibility with backend services and security. No new features will be introduced in v1.

Please use the latest version (v2) of Amplify Flutter to get started.

If you are currently using v1, follow these instructions to upgrade to v2.

If you are looking to enable triggers for the Storage Category with Amazon S3 & Amazon DynamoDB as Providers, the CLI supports associating Lambda triggers with S3 and DynamoDB events. For example, this can be useful for a use case where you want to invoke a Lambda function after a create or update operation on a DynamoDB table managed by the Amplify CLI.

For more information on this topic, please read on File Storage Lambda Triggers through our Amplify CLI documentation.
