Dynamically update toolbar options to be relevant to 'current view'

[sheyaln]

I might be grossly misunderstanding the paradigm, but the only widget that takes a toolbar seems to be the MacosScaffold widget.

According to the demo in macosui.dev: "A toolbar provides convenient access to frequently used commands and controls that perform actions relevant to the current view."

Considering the MacosScaffold widget is placed at the top of my widget tree, how can I update the items in the toolbar based on the contents of the ContentArea?

Please feel free to set me straight if there's a fundamental misunderstanding of the concept. Any help is appreciated.

Ex:

@override
  Widget build(BuildContext context) {
    return BlocProvider<MacOSWindowBloc>.value(
      value: macOSWindowBloc,
      child: MacosWindow(
        sidebar: _buildSidebar(),
        child: CupertinoTabView(
        builder: (context) => BlocBuilder<MacOSWindowBloc, MacOSWindowState>(
              bloc: macOSWindowBloc,
              builder: (context, state) {
                return MacosScaffold(
                  toolBar: ToolBar(
                    actions: [
                      ToolBarIconButton(
                          label: 'Back',
                          icon: backIcon,
                          tooltipMessage: 'Go to Previous Page',
                          onPressed: () {
                            BlocProvider.of<MacOSWindowBloc>(context)
                                .add(BackButtonClick());
                          },
                          showLabel: true),
                      ToolBarIconButton(
                          label: 'Refresh',
                          icon: refreshIcon,
                          onPressed: () {
                            BlocProvider.of<MacOSWindowBloc>(context)
                                .add(RefreshButtonClickEvent());
                          },
                          showLabel: true),
                      ToolBarIconButton(
                          label: 'Create a new rating',
                          onPressed: () async {
                            BlocProvider.of<MacOSWindowBloc>(context)
                                .add(RateIssueButtonClick());
                          },
                          icon: plusIcon,
                          showLabel: true)
                    ],
                    leading: MacosIconButton(
                      icon: const MacosIcon(CupertinoIcons.sidebar_left),
                      onPressed: () {
                        MacosWindowScope.of(context).toggleSidebar();
                      },
                    ),
                  ),
                  children: [
                    ContentArea(
                      builder: (context, scrollController) =>
                          state.buildNavigator(state.selectedIndex),
                    ),
                    ResizablePane.noScrollBar(
                      minSize: 550,
                      resizableSide: ResizableSide.left,
                      isResizable: true,
                      startSize: 600,
                      maxSize: 650,
                      child: state.buildNavigator(3),
                    )
                  ],
                );
              },
            )),
      ),
    );
  }
