formatProviderTimeout function
The stall-surface duration renderer: sub-second windows render as
<N>ms — a mis-keyed 150ms window must be recognizable verbatim in
the terminal and notice lines (gh-1617 AC4 names config values);
everything else goes through the tenths-of-a-second humanizer.
Implementation
String formatProviderTimeout(Duration d) {
final ms = d.inMilliseconds;
if (ms > 0 && ms < 1000) return '${ms}ms';
return _humanize(d);
}
