PaginatorModel class

A paginator widget for handling pagination state and rendering.

The paginator manages page state and provides rendering for pagination indicators. It can display pages as Arabic numerals ("1/10") or dots ("●○○").

Example

class ListModel implements Model {
  final List<String> items;
  final PaginatorModel paginator;

  ListModel({required this.items, PaginatorModel? paginator})
      : paginator = paginator ?? PaginatorModel(perPage: 10)
          ..setTotalPages(items.length);

  @override
  (Model, Cmd?) update(Msg msg) {
    final (newPaginator, cmd) = paginator.update(msg);
    return (
      ListModel(items: items, paginator: newPaginator as PaginatorModel),
      cmd,
    );
  }

  @override
  String view() {
    final (start, end) = paginator.getSliceBounds(items.length);
    final visibleItems = items.sublist(start, end);
    return '''
${visibleItems.map((i) => '• $i').join('\n')}

${paginator.view()}
''';
  }
}
