 The session will be terminated if the application has spent in the background more than 30 seconds or when the maximum duration of 60 minutes is reached. You can adjust the [session tracking interval](/platforms/dart/guides/flutter/configuration/releases/#sessions) to extend or shorten the duration of a single replay, depending on your needs. Note that if the application exits abnormally while running in the background, the session will also be terminated.

In this case, the integration will buffer up to one minute worth of events prior to the error being thrown.

+### Session Replay
+
+The `SentryFeedbackForm` works with <PlatformLink to="/session-replay/">Session Replay</PlatformLink> on iOS and Android in Sentry Flutter SDK `9.0.0` and later. With <PlatformLink to="/session-replay/#sampling">`onErrorSampleRate`</PlatformLink> set, the SDK buffers up to 30 seconds of the user's session and sends it when the form opens or when your app calls `Sentry.captureFeedback()`. This way, the replay shows what led the user to report the problem instead of only their interactions with the form.
