GridSheetSorter class

Default sorting logic for GridSheet columns.

This class provides the built-in comparison logic used when no custom comparator is registered for a column. It handles common data types with sensible defaults.

Comparison Rules

1. Null Values: Always sorted last (after non-null values)
2. Numbers: Natural numeric comparison (1 < 2 < 10)
3. Dates: Chronological order (earliest to latest)
4. Strings: Case-insensitive alphabetical order
5. Other Types: Converted to strings and compared alphabetically

Usage

The default comparator is used automatically. You can also call it directly for custom sorting logic:

final result = GridSheetSorter.defaultCompare('apple', 'Banana');
// result < 0 because 'apple' comes before 'banana' (case-insensitive)

• GridSheetValueComparator, for custom comparison logic
• GridSheetStateManager.setColumnComparator, to override defaults
