Hey! 👋
Not sure which channel would be the best for this.

I’m having some trouble with Multiplatform Settings library (version 1.1.0.
I’m using FlowSettings with DatastoreSettings implementation. The thing is that when I listen for changes in a property with:

settings.getStringOrNullFlow(key)

writing with:

settings.putString(key, value) //This is a suspend fun

is blocked forever, it never ends.

Am I the only one experiencing this? I did downgrade the lib to 1.0.0 and no change.

Can you show more of the context where you’re calling things? I wonder if something’s deadlocking somehow. If you have a reproducer, I’d love to take a look.

The project is quite big and private repo so I don’t have a reproducer, sorry.
Regarding the context:
I’m using KoinDI to inject a singleton FlowSettings into a class instantiated as a factory (new instance each time is needed). This class contains a couple of methods, one of them to get the flow and the other one to put some value. At least two listeners are getting updates from the same flow and the lock happens when trying to write a value there.
I just tried with ObservableSettings and it’s working as expected.

DataStore only supports one instance at a time per file, so it’s possible using a new instance each time is your issue. But in that case I’d expect an exception rather than a freeze.

[Nacho Ruiz Martin]

Datastore is actually only instantiated once because the FlowSettings is injected as a singleton.

Oh i see. I misread your comment

It’s still hard to be very helpful without seeing more actual code.
