[develop] Page Load and Navigation Tracing for Mobile

SDK

Mobile SDKs - Develop Docs

Description

While testing tracing without performance in Flutter, we realized that the OOTB experience did not link errors with page loads and navigation. Fixes for page loads have been made, at this time, and navigations are pending (issue for TTID/TTFD related to link here?)

After discussing with team working on Flutter and react-native we agreed it might be best to do a write up in develop on the expected behavior, so it can be more easily communicated to other mobile SDK developers.

getsentry/sentry-dart#2753

Suggested Solution

Add develop doc page which describes an over view of how root spans and trace lifetimes will ensure that errors associated with specific page loads and navigation will work in a similar/same way across mobile platforms at Sentry.
