Description

Adding step={1} is working in version 4.1.10, but not in 4.2.2 or 4.2.3 (I didn't test other versions), meaning the thumb is not moving (jumping) discretely between 1*N min/max values, but instead moves continuously.

Reproducible Demo

import Slider from '@react-native-community/slider';
import React, { useState } from 'react';

const SliderComponent = () => {
	const [value, setValue] = useState(0);

	return (
		<Slider
			value={value}
			step={1}
			minimumValue={0}
			maximumValue={5}
			onValueChange={setValue}
		/>
	);
};

Hello @CptFabulouso, thanks for finding and reporting!
Which platform do you observe this on?

[CptFabulouso]

Hi. I've tested this on iPhone 11 pro max simulator, not any other device.

[BartoszKlonowski]

@CptFabulouso Sure! So I will test it also for others, thanks again 👍

[BartoszKlonowski]

I confirm this issue to be the iOS only.
The tapToSeek seems to be working fine - user cannot tap to other position than defined step.

I will work on this.

Hello, @BartoszKlonowski is there any update for this issue. I couldn't use the step prop for the discrete movement of the slider.

Thanks a lot.

[BartoszKlonowski]

@doganoruc I plan to deliver the fix in the upcoming week, thank you for you patience!

Thanks a lot, I have an another question for vertical prop. Is there any problem in there too, for iOS? @BartoszKlonowski

[BartoszKlonowski]

@doganoruc There's an issue already created for vertical Slider: #196, please track the progress there.

Hi @BartoszKlonowski ,

I hope you are doing well, is there any update on your side,
I really appreciate the work you are doing! Thank you so much.

[BartoszKlonowski]

@ironbat1 Thanks for asking, I'm still working on it.

I plan to deliver the fix in the upcoming week, thank you for you patience!

You can expect a fix (along with some other fixes in 4.2.4) somewhere this week.

I really appreciate the work you are doing! Thank you so much.

I didn't see you anywhere among Stargazers, though... 🙂

Hey @BartoszKlonowski Is 4.2.4 supposed to fix this?

I'm still seeing issue;
The thumb is not dragging properly based on step prop value. Tapping on the slider works properly

I can provide more info if you need.

[BartoszKlonowski]

@dhmoon91 Sure! Give me as many details as you can (including platform).
What would be useful is the repro code sample and maybe some recording.
I'll reopen once we got this confirmed.
