Navigation

OtelNavigatorObserver tracks route transitions through Flutter navigation.

Wiring

MaterialApp(
  navigatorObservers: <NavigatorObserver>[
    if (flutterTelemetry.navigatorObserver != null)
      flutterTelemetry.navigatorObserver!,
  ],
)

What it records

• route push spans
• route pop, remove, and replace lifecycle
• optional screen-ready spans

Common attributes include:

• flutter.navigation.action
• flutter.route.name
• flutter.route.runtime_type
• flutter.previous_route.name

Naming

The default route span name follows the configured prefix, such as flutter.route <routeName>.

Use routeSpanNamePrefix and screenReadySpanNamePrefix when you need a different naming convention.
