Resource timing info for Http(s) call?

[sureshg]

Is there any way to get event callbacks for the following operations when making an Http(s) request using this package?

dnsStart
dnsEnd
connectStart
secureConnectStart
secureConnectEnd
connectEnd
requestStart
requestEnd
responseStart
responseEnd
I am looking for something similar to the analytics API available in OKHttp (square/okhttp#270)

I asked this question on dart-lang/http#141 and is being redirected here.

Having access to this kind of callbacks could be very beneficial in debugging performance issues due to network performance.
