We cannot able to use

try-catch

inside composable function. I am getting the below error

Try catch is not supported around composable function invocations.

why do you want to throw?

Just getting some error and I am trying to printstacktrace.😅

He doesn't want to throw, but catch ;)

Yes

@Michal Bacik he can catch inside the function, without calling nested

@Composable

inside the try-catch

Thanks to the way Compose can restart further down the tree on recomposition if just one small part of the UI invalidates, the try/catch may not be part of the call stack when the error happens. Any time you call a composable function, think of it being a little bit like a

launch {}

.

I really don’t see the point why you should wrap a

@Composable

with a try-catch block

No? I'd love to be able to try a block and if anything goes wrong, transactionally roll back some part of it and then emit something else as part of the catch 🙂

Well, you can try-catch inside a composable

Yes but that's not really exceptions, that's more like return value checking at each layer of the call stack
