DebugInterceptor class

Dio interceptor that emits structured, verbose debug information through a user-supplied callback.

Lucky Dart has no built-in logging dependency. Instead, you wire DebugInterceptor to your own debug output mechanism by providing the onDebug callback. The callback receives a named event string ('request', 'response', or 'error'), a short human-readable message, and a data map containing every observable field of the request or response — making it straightforward to dump to a structured logger, a developer console, or a debugging overlay.

The interceptor is only added to Dio when the connector's debugMode flag is true and an onDebug callback is provided.

Unlike LoggingInterceptor, DebugInterceptor always fires on every request and response; there is no per-request opt-out flag.

DebugInterceptor(
  onDebug: ({required event, message, data}) {
    // Route to your preferred debug sink, e.g. `print` or a dev-tools
    // overlay.
    print('[DEBUG:$event] $message — $data');
  },
);
