Tipi comuni

Consulta le proprietà delle View, i tipi di dati e gli esempi di codice.

ViewContent

Views, valori semplici o array annidati; null/undefined non producono contenuto.

type ViewContent =
  View | string | number | boolean | null | undefined | ViewContent[];

Esempio

TextContent

Conversione del testo con toString(); null/undefined restano vuoti. Componi le icone con altri Views.

type TextContent =
  | string
  | number
  | bigint
  | boolean
  | symbol
  | { toString(): string }
  | null
  | undefined;
