MultiSelectField<T> class abstract

Base abstract class for MultiSelectField variants.

This class provides two variants:

• MultiSelectField (default) - Full multiselect field with chips display
• MultiSelectField.chip - Compact chip dropdown for space-constrained areas

Example usage:

// Standard multiselect
MultiSelectField<Car>(
  data: () => carChoices,
  onSelect: (selected, isDefault) => print(selected),
)

// Chip dropdown variant
MultiSelectField<String>.chip(
  label: 'Filter',
  data: () => filterChoices,
  onSelect: (selected, isDefault) => print(selected),
)
