How to embed a iframe-thing?

I have a wiki site up and running and am thinking of transport it to Grav.

One of the sections I have is on Flutter development and I use

    {{url>http://dartpad.cn/embed-flutter.html?id=590ff0b29c87fe5e1942a36612ba1b70 100%,600}}

in my current wiki to include an iframe so that the remote content can be displayed. It is working fine.

I am wondering if a similar plugin or any mechanism can help me to do the same?

Thanks for your help!

Yes, it works! Thanks!
