Refresh the data field

Hello,

I'm new in the Garmin world, so perhaps my question is a litle but stupid... Let me know...

I have wrote a DataField that made exactly want I want on my new fenix 6x pro and I wanted the add some custonization.

For that, I add the the AppBase a function getSettingsView that allows the user to change some settings, as color for example. I put the color choosen in the Storage

My question is, how it's possible to refresh the data field to have the new color choosen ? The onSettingsChange function in the AppBase is never called...

And make, in the data field onUpdate method, a call to get from the Storage the new color is, I think, not a good idea...

Somebody can help me ?

Thanks you

Frédéric
