Overview
http_interceptor is a lightweight Flutter plugin that enables developers to intercept HTTP requests and responses, allowing for modifications such as adding headers, logging, or handling errors globally. It simplifies common tasks like authentication token injection, request/response logging, and error handling across an app. The package integrates seamlessly with the built-in http client and supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux. Designed for simplicity and flexibility, it provides a clean API for middleware-style interception without requiring complex setup.
