TrafficLineController class
Controller for managing traffic information and route progress visualization.
This controller handles:
- Route progress tracking
- Traffic speed conditions
- Road events monitoring (accidents, roadworks)
- Intermediate route points
- Dynamic route updates
The controller maintains real-time information about traffic conditions and route progress through TrafficLineModel.
Usage example:
final controller = TrafficLineController(
  navigationManager: navigationManagerInstance,
);
// Access current traffic information
print(controller.state.value.routeProgress);
print(controller.state.value.speedColors);
// Listen to traffic and route updates
controller.state.addListener(() {
  final model = controller.state.value;
  print('Route progress: ${(model.routeProgress * 100).toStringAsFixed(1)}%');
  print('Road events: ${model.roadEvents.length}');
});
The controller maintains three main subscriptions:
- Route information updates
- Route position updates
- Dynamic traffic information updates
Remember to dispose of the controller when it's no longer needed:
controller.dispose();
