Dashboard Widget: Get dashboard id

Hello,

Is there a way for a widget to determine the ID of the dashboard on which it is currently displayed?

I want to synchronize multiple widgets on the same dashboard, for example charts and issue tables, and control them through a shared filter widget. I already have the synchronization working, but the selected filter is currently shared across all dashboards that contain these widgets.

I therefore need the current dashboard ID so that I can include it in the host.storage key and keep the stored filter settings isolated for each dashboard.

Is there a supported way to retrieve the current dashboard ID from within a widget?

Best regards
