Steps:

  1. Get DevTools at Add instrumentation to measure performance and improve UX of snapshotting. #8138
  2. set DebugTimer.snapshot to DebugTimer()
  3. Run DevTools in debug mode on mac:
    flutter run --debug -d macos
  4. Connect to an app (counter?) on macos
  5. In CLI console find link for the connected DevTools, open it and:
    • Select the tab CPU Profile
    • Click ‘Start recording’
  6. In first DevTools take memory snapshot
  7. See in console that user tag is started
  8. In second DevTools click ‘Stop’
