AppSearchableMultiSelect<T> class final

Dropdown de seleção múltipla com busca: chips no trigger + filtro no overlay; selecionar não fecha. Reusa o core de dropdown.

Com allOptionLabel preenchido, a lista ganha uma opção "Todos" no topo e seleção vazia == "Todos": o trigger passa a exibir esse texto e a linha "Todos" recebe o destaque de selecionado.

Properties

allOptionLabel → String?
Label da opção "Todos", exibida como primeira linha da lista (só quando a busca está vazia). Se null, a opção não aparece. Com ela, seleção vazia == "Todos": o trigger mostra este texto e a linha "Todos" fica em destaque. Tocar em "Todos" limpa a seleção (onChanged([])); tocar num item individual sai do estado "Todos".
