Property 'scrollToEnd' does not exist on type 'SwipeableFlatList<any>'.ts(2339) about react-native-swipeable-list HOT 14 CLOSED

FWIW, PR #70 doesn't fix this.

from react-native-swipeable-list.

Ok, I have a repro 😄

from react-native-swipeable-list.

@esthor I applaud your PR #74 efforts!

I've gotten refs to the swipeable flatlist to work, but the app just tanks in terms of performance.

Where is this work, or is it too tacky to commit? :-)

from react-native-swipeable-list.

Hey @jkoutavas! I think it's because this library isn't currently exporting TypeScript type definitions. Does it work functionally and just complain about the type?

Basically, I think your setup and usage could be fine, but TypeScript will throw this error (likely) because your TypeScript compiler is saying "Hey! What a minute...I'm inferring an any type on anything that I don't have a type definition or can infer from the code, and specific things like scrollToEnd() isn't part of the any type."

Does that make sense?

I've really been meaning to add those type definitions. I was hoping to move this community PR along (#61), which would likely solve this for your case. If you'd like to reopen it and address the issues to get it ready, I'd greatly appreciate it! Otherwise, I can try to get around to it 🙏

@esthor

Thank you for the reply.

Were it just a typing issue, I wouldn't have minded. But, the error is deeper than that...

 ERROR  TypeError: _flatlistRef$current.scrollToEnd is not a function (it is undefined), js engine: hermes

... happens at runtime when attempting to scroll to bottom. And of course the scroll doesn't happen.

As far as that PR goes, sure, I'll re-open it, address the issues. But, I might need your help/further insights on understanding the issue I raised here.

For what it's worth, I'm on latest RN v0.72.5 along with accompanying React v18.2.0.

from react-native-swipeable-list.

Oh. I see. That's not great.

If you use FlatList from react-native, it works fine?

I have not tested on the latest version of React Native yet, so I'm wondering if that's going to be an issue. 🤔 😅

from react-native-swipeable-list.

Yeah, it works fine with FlatList. I'm trying to move my current implementation from it to SwipeableFlatList.

from react-native-swipeable-list.

Ok, I may need to update this library to specifically use the latest FlatList version. Starting to test now...

TL;DR -- adding refs on refs is instantly janky 😭

Ok, so I've given it the old college try. And I'm at a point where it might make sense to refactor the library in order to support refs on top of it in a performant way.

What I've done:

• I've refactored the library to TS (to make everyone's life easier, including mine 😅 )
• I've updated the example app
• I've gotten refs to the swipeable flatlist to work, but the app just tanks in terms of performance.

I am at the point where I need to step back and think a bit more about what's the best path forward. Right now, I don't think there is a quick way to get refs to work for you that I'm seeing.

I'll come back in a week or so to try again. 😕

Yeah. Is there an approach to expose the underlying FlatList ref as a property to SwipeableFlatList? Or am I being naive?

Lol, yeah, pretty tacky to commit right now. I'm going to have another go at it.

Is there an approach to expose the underlying FlatList ref as a property to SwipeableFlatList?

Yeah, that's likely how I'll need to refactor how I was doing it. Larger context was that I was in the middle of a complete JS/FlowTypes -> TypeScript and Class->Function component rewrite when doing this. 😁 So there was a lot of change not fully tested at the time.

"Soon" 🙏

@esthor I'm very appreciative that you are actively working on this. This package has been my go-to (pun intended) for a number of projects I've done. Let me know if there's anything more I can do to help.

@esthor Happy Holidays. Any news to share?
