+The started transactions will idle for a fixed amount of time, for which the default is `three seconds`. You can also change this by setting `autoFinishAfter` in the navigators constuctor.
+
+```dart
+import 'package:sentry_flutter/sentry_flutter.dart';
+
+/// Change how long navigation transactions idle before being finished
+SentryNavigatorObserver(
+  autoFinishAfter: Duration(seconds: 5)
+)
+```
 
 Child spans started will be attached to the transaction. If they run longer than the idle time, the transaction will be extended and finished when all its children are complete.
 
+If children are finished before the idle timeout, the transaction end will be trimmed, and its end time will be set to the last child end time.
+
 You can also opt out of this behaviour by setting `enableAutoTransactions` to false in the `SentryNavigatorObserver` constructor. You might do this when you only want to use navigation breadcrumbs, which can be enabled by setting the constructor parameter `setRouteNameAsTransaction` to `true`.
