This package is designed to find CCTV cameras that support the ONVIF protocol. The method for finding these cameras is the [WS-Discovery](https://en.wikipedia.org/wiki/WS-Discovery) protocol.

How to use #

import  'package:onvif/Model/OnvifDevice.dart';
import  'package:onvif/onvif.dart';

Create an ONVIF object and call the get Devices method.

List<OnvifDevice> devices = [];
ONVIF onvif = ONVIF();

To get the streaming link , all you have to do is call the getCameraUri function and send the username and password values of the camera you specified as an argument.

String uri = await onvif.getCameraUri(onvifDev, username, password);

You can play the resulting url with the vlc player. Note that to play the contents of the camera, you must change the resulting url to the following pattern.

uri.substring(0 , 7)+ "$username:$password@"+ url.substring(7 , url.length)

See the example project for a better understanding.

Support latest dependencies. (-10 points)

The version constraint in pubspec.yaml does not support the latest published versions for 1 dependency (xml).

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
