This code defines an `ActivityTrackerMiddleware` class that inherits from `BaseHTTPMiddleware`. The `dispatch` method is overridden to log the request method, URL, and processing time for each incoming request.
Here's a breakdown of the code:
This middleware can be added to the FastAPI application by including it in the list of middleware instances when creating the application instance.
