Trace class
Trace allows you to set the beginning and end of a custom trace in your app.
A trace is a report of performance data associated with some of the
code in your app. You can have multiple custom traces, and it is
possible to have more than one custom trace running at a time. Each custom
trace can have multiple metrics and attributes added to help measure
performance related events. A trace also measures the time between calling
start() and stop().
Data collected is automatically sent to the associated Firebase console after stop() is called.
You can confirm that Performance Monitoring results appear in the Firebase console. Results should appear within 12 hours.
It is highly recommended that one always calls start() and stop() on
each created Trace to not avoid leaking on the platform side.
