Version

8.6.0

Steps to Reproduce

• Use the app for more than approximately 20 minutes.
• App will start to lag when navigating to other screen.

This issue only starts happening when we enabled Sentry in our new version of app.

When checking with CPU profiler, it seems Sentry is using much of the time. I'm wondering if SentryNavigatorObserver is causing our app to lag?

Looks related to this PR comment with span_frame_metrics_collector.dart:

Does it only happen after using the app continuously for a long time?

[zhenhao-ola]

It only happens after using app for long time. The app becomes smooth back after restarting.
