HttpMetric class Null safety

Metric used to collect data for network requests/responses.

It is possible to have more than one HttpMetric running at a time. Attributes can also be added to help measure performance related events. A HttpMetric 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 HttpMetric to avoid leaking on the platform side.
