CLMediaAttachWidget class

Widget riutilizzabile per gestire i media allegati a una risorsa.

Si passa il resourceIdentifier (es. l'id dell'evento o del prodotto) e i callback onUpload / onDelete per delegare le operazioni API al chiamante.

Esempio d'uso:

CLMediaAttachWidget(
  resourceIdentifier: widget.eventId,
  initialMediaList: vm.attachedMedia.map((m) => CLAttachedMedia(
    id: m.id, url: m.url, originalName: m.originalName, path: m.path,
  )).toList(),
  onUpload: (media) async {
    // upload via API, ritorna il nuovo media
    final result = await myUploadCall(media);
    return result != null
        ? CLAttachedMedia(id: result.id, url: result.url, ...)
        : null;
  },
  onDelete: (id) async => await myDeleteCall(id),
  onMediaChanged: () => vm.refreshMediaList(),
)
