Learn how to integrate FlutterFlow with Amazon DynamoDB in this step-by-step guide. Simplify your app development process with clear instructions and practical tips.
Amazon DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). It offers fast and predictable performance with scalability. DynamoDB allows users to create database tables that can store and retrieve any amount of data and serve any level of request traffic. This service automatically distributes data and traffic over servers to dynamically manage each customer's requests, offering high availability and data durability.

final credentials = AwsClientCredentials(
accessKey: dotenv.env['AWS_ACCESS_KEY\_ID']!,
secretKey: dotenv.env['AWS_SECRET_ACCESS\_KEY']!,
