How exactly do one find out which item triggered an action ?

[Roms1383]

Hi, thanks first, component looks neat indeed!

I'm still very confused how to find out which Slidable triggered a SlidableAction, especially when these are generated from a dynamic list, let's say a remote third-party API for example.

Currently I'm stuck around the exact same issue described in #264.

I've looked quickly throughout the example, read through the wiki, noticed some similar questions (#218, maybe others) and I'm still not really clear on how to pipe, e.g. some identifier with my data.

My guess, among other attempts, was that ValueKey(uuid) might be retrievable through Slidable.of(context).key but I tried different ways, to no avail.

What did I miss here ?
Thanks for your time.

I'm going to add a bit code, so it's more contextual.

The values in a const list literal must be constants.
Try removing the keyword 'const' from the list literal.dart[non_constant_list_element](https://dart.dev/diagnostics/non_constant_list_element)

Ok I actually missed a simple const on my ActionPane 😅 No it actually works just as expected, no need for static or method chaining or anything, sorry !
