Communication problems between flutter-webrtc and aiortc

[YuioiuY]

Hello everyone, I use your application and server to debug my program, which is written on the basis of aortic. Locally everything works without problems, the connection is established, the picture is there, the connection is stable. But there are nuances, when I want to connect from another network, I need to exchange candidates, if I calmly take and take data from a candidate in airtc, then in order to form candidates for flutter-webrtc, problems arise. I noticed the following differences:

1.foundation in it looks like f98981c30fc331fe258681c79fbc1ab5, and in flutter-webrtc like this 1114921598
2.this is what is in the candidate that comes to me with flutter-webrtc and which is accordingly expected as I understood it network-id and network-cost

The question is, is it critical that the foundation type is so much different and that there is no network-id and network-cost in my candidates?
And unfortunately I can't find an example of an ideal candidate and his arguments, which of the arguments are fundamental, and which are of secondary importance, if there is information, please share, otherwise I've been going crazy for 2 weeks on the sly ^_^
