@dataclass
class SolutionConfig:
    """
    Manages configuration parameters for Ultralytics Vision AI solutions.

    The SolutionConfig class serves as a centralized configuration container for all the
    Ultralytics solution modules: https://docs.ultralytics.com/solutions/#solutions.
    It leverages Python `dataclass` for clear, type-safe, and maintainable parameter definitions.

    Attributes:
        source (str, optional): Path to the input source (video, RTSP, etc.). Only usable with Solutions CLI.
        model (str, optional): Path to the Ultralytics YOLO model to be used for inference.
        classes (List[int], optional): List of class indices to filter detections.
        show_conf (bool): Whether to show confidence scores on the visual output.
        show_labels (bool): Whether to display class labels on visual output.
        region (List[Tuple[int, int]], optional): Polygonal region or line for object counting.
        colormap (int, optional): OpenCV colormap constant for visual overlays (e.g., cv2.COLORMAP_JET).
        show_in (bool): Whether to display count number for objects entering the region.
        show_out (bool): Whether to display count number for objects leaving the region.
        up_angle (float): Upper angle threshold used in pose-based workouts monitoring.
        down_angle (int): Lower angle threshold used in pose-based workouts monitoring.
        kpts (List[int]): Keypoint indices to monitor, e.g., for pose analytics.
        analytics_type (str): Type of analytics to perform ("line", "area", "bar", "pie", etc.).
        figsize (Tuple[int, int], optional): Size of the matplotlib figure used for analytical plots (width, height).
        blur_ratio (float): Ratio used to blur objects in the video frames (0.0 to 1.0).
        vision_point (Tuple[int, int]): Reference point for directional tracking or perspective drawing.
        crop_dir (str): Directory path to save cropped detection images.
        json_file (str): Path to a JSON file containing data for parking areas.
        line_width (int): Width for visual display i.e. bounding boxes, keypoints, counts.
        records (int): Number of detection records to send email alerts.
        fps (float): Frame rate (Frames Per Second) for speed estimation calculation.
        max_hist (int): Maximum number of historical points or states stored per tracked object for speed estimation.
        meter_per_pixel (float): Scale for real-world measurement, used in speed or distance calculations.
        max_speed (int): Maximum speed limit (e.g., km/h or mph) used in visual alerts or constraints.
        show (bool): Whether to display the visual output on screen.
        iou (float): Intersection-over-Union threshold for detection filtering.
        conf (float): Confidence threshold for keeping predictions.
        device (str, optional): Device to run inference on (e.g., 'cpu', '0' for CUDA GPU).
        max_det (int): Maximum number of detections allowed per video frame.
        half (bool): Whether to use FP16 precision (requires a supported CUDA device).
        tracker (str): Path to tracking configuration YAML file (e.g., 'botsort.yaml').
        verbose (bool): Enable verbose logging output for debugging or diagnostics.
        data (str): Path to image directory used for similarity search.

    Methods:
        update: Update the configuration with user-defined keyword arguments and raise error on invalid keys.

    Examples:
        >>> from ultralytics.solutions.config import SolutionConfig
        >>> cfg = SolutionConfig(model="yolo11n.pt", region=[(0, 0), (100, 0), (100, 100), (0, 100)])
        >>> cfg.update(show=False, conf=0.3)
        >>> print(cfg.model)
