CheckboxList class Components InteractableComponents

A scrollable list of checkboxes arranged either vertically or horizontally.

The CheckboxList component renders a list of labeled checkboxes, supports navigation via arrow keys, and allows toggling selections with the space or enter keys.

Each item in the list is represented as a Checkbox component internally. Focus and hover states are managed to provide interactive feedback.

Features

• Vertical or horizontal layout (direction).
• Customizable spacing between items (spacing).
• Supports ANSI color customization for selected, hovered, and text states.
• Optional border styling using BorderStyle.
• Keyboard navigation with arrow keys.
• Selection toggling via space or enter.

Example

CheckboxList(
  items: ['Option A', 'Option B', 'Option C'],
  selectionColor: AnsiColorType.green,
  hoverColor: AnsiColorType.yellow,
  textColor: AnsiColorType.white,
  borderStyle: BorderStyle.rounded,
  spacing: 1,
  direction: Axis.vertical,
)
