[Flutter] Dio request throttler

A simple request throttler (rate limiter) for Dio, which ensures a minimum interval between which each request is fired.

Usage

// Simple usage
dio.interceptors.add(
  DioThrottler(const Duration(milliseconds: 500)),
);

// Output debug info when throttled
dio.interceptors.add(
  DioThrottler(
    const Duration(milliseconds: 500),
    onThrottled: (req, until) {
      print('${req.uri.toString()} has been delayed until ${until.toString()}');
    },
  ),
);
