 To receive UI jank information, implement your own reporter (`JankDetectedReporter`). Once you have the jank information, you can save the stack traces to a file, or upload them to your server, and symbolize them using the `flutter symbolize` command.

 ### Symbolize Automatically
 Some tools, like Firebase and Sentry, can automatically symbolize the stack traces if you upload the symbols. This is helpful if you do not have a self-hosted server.

+
+In some cases, the stack traces may not accurately reflect the exact invocation order of the Dart code. This issue requires further improvement.
