I think that the issue at hand is, that the SlidableAction can not have a fixed size at the moment, but always resizes based on the extentRatio. This is great in itself, but it might be beneficial for a few cases to have the extentRatio: null and set a fixed width in the `SlidableAction` / `CustomSlidableAction`

(If you think this is another issue, than the one I highjacked rn, please tell me and I open a seperate one. I was inspired by this)

You can use the following as a temporary fix while waiting for fixed-size ActionPane to be released:

extentRatio: size / MediaQuery.sizeOf(context).width,

^ where size is the fixed width that you want for your action pane.

Note: it won't resize with the window while being open, but it will have correct size on next opening (after window resized).
