Statistics for Pings

[psycotica0]

Currently when the ping is done it tells me to total duration, but that's mostly just 1000ms * number of pings.

It would be nice to get min, avg, max ping, at least, like the ping command gives:

We use a underlying library dart_ping and it only provides a total time. I can open a issue in underlying library to build this use case and tag you there. If library owner agrees to provide this data then we can show easily in our app.

I opened an issue in dart_ping to provide/expose these values so that I can consume it.
