11/05/2020, 4:55 PMMost likely, yes. Objects and all other top-level constructs are frozen on creation, as are all its properties. Even though its a MutableMap, that map is still frozen and can’t be edited

11/05/2020, 4:55 PMok, what about create a singleton with companion ?
Pablo Caviglia
11/05/2020, 4:56 PMshould that work fine ?
c
Casey Brooks
11/05/2020, 4:57 PMNope, companion objects are still considered top-level. Super annoying, I know. You will have to use one of the atomics from the Stately lib to do any modification on singletons https://github.com/touchlab/Stately

11/05/2020, 4:58 PMi just want to have a global var to store references to fonts
Pablo Caviglia
11/05/2020, 4:58 PMor to whatever

Casey Brooks
11/05/2020, 5:00 PMYeah I know, it drives me crazy. The alternative is to make it a local object and use DI to it where you need it. Korge has an injector module which could probably make this a bit less painful

11/05/2020, 5:00 PMuhmm, good idea

11/05/2020, 5:00 PMwhat about korge 2 with its new kotlin mp version?
Pablo Caviglia
11/05/2020, 5:00 PMsolved in there?

Casey Brooks
11/05/2020, 5:01 PMI haven’t tried 2.0 yet. But it’s not a limititation of korge, it’s a fundamental restriction from Kotlin Native. No way around it other than using atomics or not using global objects

Pablo Caviglia
11/05/2020, 5:04 PMok, will go with DI, in fact i like the idea of using DI in the project from an architecture point of view

11/05/2020, 5:14 PMis there any doc apart from this page regardin korinject?
