TrafficController class

This controller handles:

• Traffic layer visibility toggling
• Traffic intensity score tracking
• Traffic status monitoring

The controller provides real-time traffic information through TrafficModel, allowing users to monitor traffic conditions and control traffic visualization.

Usage example:

final controller = TrafficController(
  map: mapInstance,
);

// Toggle traffic visualization
controller.toggleTraffic();

// Access current traffic information
print('Traffic score: ${controller.state.value.score}');
print('Traffic status: ${controller.state.value.status}');

// Listen to traffic condition changes
controller.state.addListener(() {
  final model = controller.state.value;
  print('Traffic intensity updated:');
  print('Score: ${model.score}');
  print('Status: ${model.status}');
});

The controller maintains a single subscription to traffic state changes and provides a simple mechanism to toggle traffic visualization on the map.

Traffic score typically ranges from 0 to 10, where:

• 0-3: Light traffic
• 4-7: Moderate traffic
• 8-10: Heavy traffic

Remember to dispose of the controller when it's no longer needed:

controller.dispose();
