Esphome - lvgl - widget arc - update problem

on one of my pages, I have an arc. I am able to update the value of the arc. But now I would like to update the start_angle. Does anyone know how to do so ?

  pages:
  - id: test_page
    widgets:
         - arc:
            align: CENTER
            id: my_arc
            start_angle: 255
            end_angle: 345           
            value: 0
            min_value: -100
            max_value: 0

    on_something:
      then:

        **# THIS WORK**
        - lvgl.arc.update:
            id: my_arc
            value: !lambda return x;

       **# THIS DOES NOT WORK (can't even compile)**
        - lvgl.arc.update:
            id: my_arc
            start_angle: !lambda return x;

Does it compile if you update value AND start_angle?
If not, what error you get?

 [start_angle] is an invalid option for [lvgl.arc.update]. Did you mean [state], [transform_angle]?
          start_angle: !lambda |-
            return x;

There is currently no way to update the start angle at run time. It’s doable, though both start and end angles would have to be specified.

Raise a feature request.

Do you know if it is possible to use an arc but counterclockwise ?

Per the docs, yes.
