/// A specialized input field for selecting and displaying time.
///
/// [MihTimeField] provides a read-only text input that, when tapped,
/// opens the system time picker. It ensures a consistent user experience
/// by forcing a **24-hour format** and updating an external [controller].
///
/// Features:
/// * **System Picker Integration**: Wraps [showTimePicker] with a custom
/// [MediaQuery] to enforce 24-hour time regardless of device settings.
/// * **Consistent UI**: Shares the same design language as [MihTextFormField],
/// including [elevation], [borderRadius], and labeling logic.
/// * **Form Validation**: Fully compatible with [Form] widgets via the
/// [validator] property and internal [FormField] state tracking.
/// * **Visual Feedback**: Displays a thick red border and error text
/// automatically upon failed validation.
///
/// ### Example:
/// ```dart
/// MihTimeField(
/// controller: startTimeController,
/// labelText: "Shift Start",
/// required: true,
/// elevation: 2.0,
/// validator: (value) => value == null ? "Please pick a time" : null,
/// )
/// ```

/// The secondary color of the date picker
final Color? secondayColor;
/// The controller that stores and displays the selected time string (HH:mm).
final TextEditingController controller;
/// The label displayed above the time input.
final String labelText;
/// Whether the field is mandatory. Displays "(Optional)" if false.
final bool required;
/// The width of the input field container.
final double? width;
/// The height of the input field container.
final double? height;
/// The corner radius of the input field. Defaults to 8.0.
final double? borderRadius;
/// The shadow depth for the input box.
final double? elevation;
/// Whether to use Dark Mode styling for borders and error text.
final bool? darkMode;
/// Standard Flutter validator for form integration.
