[LVGL] Allow Arc Range min and Range max to be assignable

[scruplelesswizard]

Is your feature request related to a problem? Please describe.

I have several arc widgets that are embedded in user widgets for reuse. However, the range for those arc widgets is dynamic based on other variables (i.e. two servos are configured, one with a 180 degree arc, and the other with a 270 degree arc. Each instance of the user widget controls one of the servos.)

Describe the solution you'd like

I want to be able to add an input to the arc widget and assign that input to the value of Range min and Range max

Describe alternatives you've considered

• Reconfigure the widget dynamically at runtime

Additional context

• None

Just to clarify, "Assignable" is used when the property has read/write semantics, such as the "Value" property in the Arc widget, because the Widget can also set a "Value". In the case of "Range min" and "Range max", when the widget never changes them, it will be Expression (if using EEZ Flow) or Variable (if not using EEZ Flow).

I will add this in the next version.

Expression or variable would be fantastic! Thank you ❤️

If there is anything I can do to help with a PR please let me know
