SpeedLimitController class

Controller for managing speed limits, speed cameras, and speed violation monitoring during navigation.

This controller handles:

  • Current speed limit monitoring
  • Speed limit violations detection
  • Speed camera notifications
  • User location tracking
  • Route position monitoring

The controller provides comprehensive speed-related information through SpeedLimitModel, including current speed limits, violations, and speed camera warnings.

Usage example:

final controller = SpeedLimitController(
  navigationManager: navigationManagerInstance,
);

// Access current speed information
print(controller.state.value.speedLimit);
print(controller.state.value.exceeding);

// Listen to speed-related updates
controller.state.addListener(() {
  final model = controller.state.value;
  if (model.exceeding) {
    print('Warning: Speed limit exceeded!');
  }
  if (model.cameraProgressInfo != null) {
    print('Approaching speed camera');
  }
});

The controller maintains six main subscriptions:

  • Location updates for current speed
  • Route updates for speed limit data
  • Position updates for current speed limits
  • Speed violation monitoring
  • Speed camera notifications
  • Navigation state changes

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

controller.dispose();
