I tried to find tree view select in react native, But, I couldn't find any. I also tried to generate my own, but it will take more time to develop and need to fix many things that I can't do right now.
Can anybody provide inputs on which library or component use for tree multi-select inputs?
Thank you in advance.

For school, I have to make my first app with React Native. It's a family tree app; my teacher said it's the best choice to make that with all View-elements, even the lines between family members. But I think that won't ever be possible to calculate all distances perfectly.
Isn't there any other way to make this kind of app?
I think you are right and you need to take something like https://github.com/software-mansion/react-native-svg
With SVG you can draw shapes and arrows to connect your tree items.
For React exists a beautiful library called https://reactflow.dev. Unfortunately, it is a Web-only solution, but you can check how they render trees and repeat it in RN.
Also, read this article about storing tree data in JS https://medium.com/#iampika/javascript-trees-b8f3b4261c3a it should be helpful.

** anyone who can help me to resolve this. I am tired of this and now this becomes a headache for me. help will be really appreciated. ia m trying on this for one month but invain.**
Take a look at the docs specifically about the attributes maxToRenderPerBatch,updateCellsBatchingPeriod and removeClippedSubviews. In your case, it's rendering 50 items per batch of render, the updateCellsBatchingPeriod maybe is making the list update itself longer than expected and maybe if you set the prop removeClippedSubviews to true the list is going to stay fluid as you want.
I'm trying to run end to end tests on an Expo Web project with Playwright. I was hoping that when I added a testId prop to a React Native view it would be converted to a data-testid so I could select the element for my tests.
However, it doesn't do this so I can't figure out a good way to select the elements. So far the best thing I can come up with is to add an accessibility label to the element.
Does anyone know a better way to add test id's to react-native expo projects that'll be tested on the web?
You can do this!
I may have made a casing mistake. You add a testID prop on the react native component and then query for div['data-testid="sampleId"']
Here's a code example: https://github.com/expo/expo/blob/b655ff28d924e2274c627294778a02dbec1268db/apps/bare-expo/e2e/TestSuite-test.web.js#L68

You could use this library:
https://github.com/react-native-material-design/react-native-material-design
I think it can solve your problem
This RN starter has an example as well:
https://github.com/infinitered/ignite
You should not implement it from scratch yourself but instead you can use a starter project like this. If you want these animations on the drawer icon you can also check the Airbnb's Lottie.

At the time, this one worked for me (0.63.4). The others I found were from previous versions (0.45) and required a lot of adjustments regarding newer version implementations. No other extra files are needed except these ones after creating a unmanaged blank project:
App.js
LoginScreen.js
HeaderComponent.js
FirstScreen.js
SecondScreen.js
I'm newbie that learning react native and I want to implements directory structure tree effect like below.
Is there any 3rd part libs which could help me?
thanks..
You could use collapsible for the collapse behaviour and a normal list for the rest of the behaviour.
