How solve show dialog feature

How solve show dialog in decompose?
Is it just differen child component?
thanks

Hello. I believe it depends on the complexity of the dialog. Relatively simple dialogs can be just part of the state of a component. E.g. there may be a field in the state, which is observed in the UI and the dialog is displayed.

Complex dialogs can be extracted to a separate component. Such a component can be controlled by a dedicated Router, or can be permanent with methods to show/hide the dialog. Depends on the use case.

Also please see the related discussion in the old repository: badoo/Decompose#59

Big thanks! I think toast message should be show same way with "callback" to state

Just for reference, because I tried to solve this issue with a dedicated router by using ChildStack. Besides ChildStack there is a better navigation element that can be used called ChildOverlay (see here).

I didn't know that until I tried to find a way to initialize a ChildStack without any child (and failed). 😅

[arkivanov]

Thanks for point that out! ChildStack can be also used to show a dialog, e.g. there could be two configurations - None and Dialog. And you could replace one with another. But indeed, ChildOverlay should be a better way for dialogs.

[malliaridis]

That's correct. However, with the configuration of None I still have to load a view into a container (at least the way I trie to set things up in Android with StackRouterView).

So ChildOverlay came for the rescue. 😄
