Dio is a cross-platform HTTP client for Dart designed to manage network requests and data communication across mobile and desktop applications. It provides a comprehensive framework for executing standard web operations while handling complex tasks such as request lifecycles, connection security, and global configuration.
The library distinguishes itself through an extensible architecture that allows developers to hook into the request and response pipeline. By utilizing interceptors and custom network adapters, users can modify traffic, perform authentication, and swap underlying networking implementations to meet specific platform or proxy requirements.
Beyond basic request execution, the project supports advanced traffic management and data handling. This includes automatic payload transformation between formats, reliable multipart file uploading with progress tracking, and the ability to cancel active operations to optimize resource usage. It also incorporates security features such as server certificate verification to maintain secure connections.
