"Null check operator used on a null value" in RPUITaskState

I get a "Null check operator used on a null value" in line 351 in RPUITaskState:

I come from pushing an RPUITask on the navigator like this:

I can see that the construct Theme.of(context).extension<RPColors>()!.... is used in many places in RP, so maybe a more general problem?

Ok - I solved it by using the RP themes in my app, like this:

The problem occurs when I use the default ThemeData.dark() theme.

BUT - the RP should be able to work also with other themes than the RP themes, and especially the default ones.....

It can work with any theme, but it you're using the Research Package's names for colors then you must somehow define them in your project. You cant try to get a Color from the RP and expect to find it in the default themes. The way to override the color name in any theme is with the .copyWith command i think.
