PlaybackStatus would be enough ?

[seyedmostafahasani]

I think it's better to add the prefix T before type names, meaning playbackStatus would be a type. Similarly, we can add an I before interface names
FX: type TSample = {} and interface ISample = {}
WDYT?

As Robert Martin wrote in his "Clean Code" - T, I, Enum, List (and so on) prefixes/suffixes before types, interfaces, enums (and so on) are meaningless.

We are not necessarily need to follow what he writes in his books, but it's better to follow guidelines that are accepted in the project you are working on (for example, as I can see in this project suffixes/prefixes are not used)

@seyedmostafahasani
It's a great idea and something I've been wanting.
But in new arch, functions called via ref can't have a return value. Current implementation of save or getCurrentPosition is tricky and may be deprecated in the future via RN Core, so using callback props may be a better approach for now.
(This is why I made it so that library authors see deprecation warning when using getReactTag.)

Thanks for informing me. I think we can use this method until the RN core team decides on it. If they deprecate it, we can implement a new approach using callback props.
WDYT?

@seyedmostafahasani if it is deprecated, It is nopt a good idea to use it.
BTW a possible implementation would be to implement the event callback on native side.
Register an handler in Video.tsx and the save the last state in a Ref.
Then the getter will just return the ref value.
