I'm implementing a 'light-dark-toggle" button to choose between these 2 themes. Currently I have 1 uniqueValueRenderer with a attribute FIELD. I was trying to add an attribute to the view object and using this value to check for light / dark mode.

($view.night == 1), 'night', 'day'

But unfortunately it's not possible to add custom attributes to the view and it's not possible to use $view.night with valueExpressions:

Why is view.scale the only one ?

And how to achieve dark / light without updating all features when toggling to dark or light

 

Thanks
