ToolbarItem class sealed

A single item in the viewer's main toolbar.

Hand a list of these to NutrientControllerInterface.setMainToolbarItems (reachable from NutrientDocumentView.onControllerReady). There are two kinds, both usable directly in the list — no wrapper needed:

• a ToolbarItemType value (e.g. ToolbarItemType.zoomIn) — a built-in item
• a CustomToolbarItem — a custom button backed by a Dart onPressed

The call is re-appliable at any time, so you can add / remove / enable / disable items dynamically.

NutrientDocumentView(
  documentPath: path,
  onControllerReady: (controller) {
    controller.setMainToolbarItems([
      ToolbarItemType.zoomOut,
      ToolbarItemType.zoomIn,
      CustomToolbarItem(
        id: 'say-hello',
        title: 'Hello',
        onPressed: () => debugPrint('toolbar button tapped'),
      ),
    ]);
  },
);

Platform parity

• CustomToolbarItem — a custom button backed by a Dart onPressed callback — works on Android, iOS, and Web. On Android/Web it sits in the viewer's document toolbar; on iOS it's added to the navigation bar.
• ToolbarItemType — reorder/remove the viewer's built-in items — is honored on Web only; Android and iOS ignore built-in entries (the custom items in the same list still apply).
