Hello, trying to achieve a Todo List in Compose, however, when I create a

@Model

class which has a list, adding elements to that list don’t trigger the drawing of the model on the screen. In order to have it working I added a

counter

to that model class. Increasing that

counter

whenever I add something to the list triggers the drawing of the model on the screen. (https://gist.github.com/lnicolet/039d2fe76e19e859582e32625ac411e7, https://gist.github.com/lnicolet/cb49c5a4021efc3b784bf95ec5755321). Working and not working examples in the links. Is there a different way to have it working with

lists

?

As far as I know,

@Model

tracks only changes of its properties. You are using

MutableList

, so you don't trigger property setter. Use

List

instead and you will be fine

Thanks! Another question, how can I achieve tracking changes on items inside the list itself being propagated to the class which wraps the list? E.g.: changing the

isDone

to trigger an update

Not sure, but you can try to use

@Model

on such classes as well.

I am already 🙂

@Luca Nicoletti I saw

@Pivotal

annotation does something like this

Hey @Luca Nicoletti Did you manage to get your list to work?
