TrackerLevel class abstract

An abstract class that defines values for different Tracker levels.

TrackerLevel provides a standardized way to represent different status or priority levels in tracker components. Each level defines both a visual color and descriptive name for consistent representation across the UI.

Predefined Levels

The class includes several predefined levels for common use cases:

• fine: Green color, typically for healthy/good states
• warning: Orange color, for cautionary states requiring attention
• critical: Red color, for urgent states requiring immediate action
• unknown: Gray color, for undefined or unavailable states

Custom Levels

Custom tracker levels can be implemented by extending this abstract class and providing color and name implementations.

Example:

// Using predefined levels
TrackerData(
  level: TrackerLevel.critical,
  tooltip: Text('System Alert'),
);

// Creating custom level
class CustomLevel implements TrackerLevel {
  @override
  Color get color => Colors.purple;

  @override
  String get name => 'Custom';
}
