dart:developer: log does not print timestamps #7989

Description

@ricardoboss

In a fairly big project, we have been using dart:developer's log function to... well... log everything. (actually, we have an abstraction layer above it, but I digress...).

The only issue I have with the log function is that it prints no timestamps in the Android Studio debug console:

Is there a way to enable this? Or is it something that gets lost when debugging with Android Studio?

The dart:developer package appears to provide this information, according to dart-lang/sdk#60450 (comment)
