Deno APIs missing in Deno runtime

[kevgeoleo]

Hi,

I am using deno 1.45.2.
I am trying to using Deno APIs like Deno.listenDatagram API (https://docs.deno.com/api/deno/~/Deno.listenDatagram)
but I get "error: Uncaught (in promise) TypeError: Deno.listenDatagram is not a function
const listener1 = Deno.listenDatagram({` "

Is it a problem with the deno version or is the API deprecated?

Thanks

This is an unstable API, you need to pass --unstable or --unstable-net flag to enable this API.
