10/04/2023, 6:32 PMHi @Arkadii Ivanov is there a way to preserve a dialog during orientation change and execute the correct lambda?
I have a component with a slot-navigation
I have set persistent to true
My Dialog-Config looks like this:
Copy code
@Parcelize
data class DialogConfig(
val title: StringResource,
val message: StringResource,
val onConfirm: () -> Unit = {},
) : Parcelablea

10/04/2023, 6:37 PMYou should never have lambdas in your persistent configurations. Configurations are serialized, and you are basically leaking everything that is captured by the lambda.

10/04/2023, 6:37 PMJust supply the callback when you instantiate the dialog component

10/04/2023, 6:39 PMso If I have two different dialogs for different usecase then I have to supply to different callbacks right?

10/04/2023, 6:40 PMYep

10/04/2023, 6:40 PMthats the only way ... only simple callbacks are working otherwise its leaking due to the lambda bound to a component

10/04/2023, 6:41 PMI don't get it. If you pass callbacks via constructor and don't put callbacks in configurations, there should be no leaks.

10/04/2023, 6:48 PMhard to explain. I thought I could pass different actions via config to my dialog component, but that is obviously not working because If I do so my components are not cleaned up correctly. Aftern rotation I do have 2 components of the same type. Thats because I added an onConfirm lambda via config and the old component is not cleaned up

10/04/2023, 6:49 PMYou can distinguish your cases when creating the dialog component, based on the configuration
You can have separate configuration classes for different cases

Jan
10/04/2023, 6:50 PMyes, maybe thats the problem. I thought I could just have one global config and pass lambda-callbacks to it

Arkadii Ivanov
10/04/2023, 6:51 PMYeah. That's an incorrect approach 🙂

Jan
10/04/2023, 6:52 PMok, I will try with several configs. In my specific case a dialog config If I really want to delete something and a dialog config If I really want to cancel the current changes
a
Arkadii Ivanov
10/04/2023, 6:53 PMYou can also add an enum to the configuration, and use that for distinguishing. That would be another way.
