Profiler does not show class and method for closures

Observatory:

DevTools:

CC @bkonyi if you know how observatory might be getting the class and method for the closure. The code to generate the name in DevTools is as follows:

 String? nameForStackFrame(_CpuProfileTimelineTree current) {
 final className = current.className;
 if (className != null) {
 return '$className.${current.name}';
 }
 return current.name;
 }
