feat(tracing): Emit app.vitals.start.screen on standalone app start#6369
Open
Conversation
…RN-691) Set the `app.vitals.start.screen` attribute on the standalone `app.start` transaction from the current route tracked by the tracing integration. Unlike the non-standalone `ui.load` transaction (named after the screen, which Relay backfills from), the standalone transaction is named `App Start`, so the screen is set explicitly. Omitted when no route has been registered yet at capture time. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
