Usage inside scrollview

[mwerder]

Does anyone have experience with how to use it inside a scrollview?

It highlights the components outside the view. So even if I scroll down it is not visible.

I also tried a walkaround by using the handleOnStepChange() callback to stop() the animation after the first step then scroll down my view and start(step) again at the desired step. But it's very ugly and also doesn't work, the animation does not start again.

Hello @xcarpentier, Can you help me to add before and after events when calling the next step. Thank you.

Hi Sorry, it's not yet handled and I'm really busy. Is that possible for someone to make some technical study first to know how to do it? thx

Perhaps the start function should have an optional scrollView prop just like the start from react-native-copilot: start(fromStep?: string, scrollView?: React.RefObject)

I'm studying both libs and only made it work inside ScrollView with react-native-copilot. That's how it worked:

• wrap desired components to highlight inside another ScrollView;
• pass ref from ScrollView to start function;
• setTimeout to prevent highlighting outside of the component when mount.

import React from 'react'
import { ScrollView } from 'react-native'
import { copilot, walkthroughable, CopilotStep } from 'react-native-copilot'

const TourView = walkthroughable(ScrollView)

const ParentComponent = ({ start, copilotEvents }) => {
  const refScrollView = React.useRef()

  React.useEffect(() => {
    const tourTimeout = setTimeout(() => {
      start(false, refScrollView.current)
    }, 300)

    copilotEvents.on('stepChange', (step) => console.log(`Step is ${step.name}`))
    copilotEvents.on('stop', () => console.log('Tour ended'))

    return () => {
      clearTimeout(tourTimeout)
      copilotEvents.off('stepChange')
      copilotEvents.off('stop')
    }
  }, [])

  return (
    <ScrollView ref={refScrollView}>
      <CopilotStep order={1} name='step1'>
        <TourView>
          <CustomComponent1 />
        </TourView>
      </CopilotStep>
      <CopilotStep order={2} name='step1'>
        <TourView>
          <CustomComponent2 />
        </TourView>
      </CopilotStep>
    </ScrollView>
  )
}

export default copilot()(ParentComponent)

Hello @xcarpentier

Please review pull request for this issue , https://github.com/xcarpentier/rn-tourguide/pull/112

[christianariola]

Hello @krunal-lw can you provide an example on how to use the changes you made for the scrollview?

[Haseeba393]

Really thanks krunal for making this PR, this helps me to implement the scrolling and also for bottomsheet. Thanks again

[Haseeba393]

the above PR must be merge as it has the scrolling handled

[christianariola]

Hello @Haseeba393

How did you implement it?

[Haseeba393]

Brother I checked @krunal-lw PR and did all the changes he did in his PR and it's working absolutely fine. It's all about to pass the ref of your desired component down to rn-tour package and thruh ref you can do whatever you want to your component. @krunal-lw is doing same thing for scroll view

[christianariola]

Thank you. I'll check it out.

[Haseeba393]

Your welcome, if you will need any help in implementation, then please let me know. Thanks

[krunal-lw]

Your welcome @Haseeba393

@christianariola - Let me know if still facing issue to implement with scroll

[christianariola]

Thank you @krunal-lw, I decided to switch to copilot as I needed this feature to be done asap. may package is in js not ts that's why I can't implement it base on your PR

[Egehanozsoy]

Can we have have this feature please, thanks

[krunal-lw]

@Egehanozsoy Hey buddy, you can checkout this version https://github.com/xcarpentier/rn-tourguide/pull/112,

Hope this will help to you. thanks

[antoniel]

Yo @krunal-lw,

Thank you for implementing the solution for this issue. I was testing it and I noticed that if the first step of the tour requires scrolling, it won't work properly because of how the ref is set in the state along with the start method. In this situation, the validation in the if (scrollRef && step) in the setCurrentStep function will fail, so will not trigger the scroll. My solution was to create a new parameter localScrollRef?: React.RefObject<any>, so in the first trigger of start we can pass ahead the _scrollRef?: React.RefObject<any>:

const setCurrentStep = async (key: string, step?: IStep, localScrollRef?: React.RefObject<any>) => {
    const actualScrollRef = scrollRef ?? localScrollRef

In the setCurrentStep we get a new variable actualScrollRef (sorry by bad naming hehehe),

  const setCurrentStep = async (key: string, step?: IStep, localScrollRef?: React.RefObject<any>) => {
    const actualScrollRef = scrollRef ?? localScrollRef
    return await new Promise<void>(async (resolve) => {
      if (actualScrollRef && step) {
       // ...

Feel free to implement this on your PR or follow a different path to fix this behavior o/

[krunal-lw]

@antoniel Thanks for heads up, I will implement your solution in my PR ,

Thanks once again, Appreciated

[JCYDigitalinnov]

@krunal-lw

I love your PR, but I encounter this problem TypeError: Cannot read property '_nativeTag' of null

This happens when I reset the navigation, and start the tour again the error occurs.

The problem is it happens sometimes. The solution I got is to restart the app to work it again

[Drzaln]

Hi guys, how I can use PR from @krunal-lw ? I try to patch the package but it didn't working

[kjethi]

@Drzaln Hey buddy, you can checkout this version https://github.com/xcarpentier/rn-tourguide/pull/112,

Hope this will help to you. thanks

[Drzaln]

Hi @kjethi I can't install with that version I already run yarn add rn-tourguide@xcarpentier/rn-tourguide#pull/112

but it doesn't work

[krunal-lw]

Hey @Drzaln , Can you please try yarn add krunal-lw/rn-tourguide I think this will work

Or add below line in your package.json file and run yarn install

"rn-tourguide": "krunal-lw/rn-tourguide",

[Drzaln]

Hi @krunal-lw Yep it works, I'm using this "rn-tourguide": "https://github.com/krunal-lw/rn-tourguide.git",

and also I downgrade the yarn to v1, previously using yarn v3

[nihatt]

hi @krunal-lw thanks for the major help it works perfectly, but i have another problem First i use it in the scrollview and it works perfectly but at step 3 i want to go outside the scrollview and use it in the sticky header which is a normal view above the scroll view and it gives me an error called

` view <RCTShadowView: 0x7fac67d90610; viewName: RCTView; reactTag: 105; frame: {{0, 0}, {234, 24}}> (tag #105) is not a descendant of <RCTShadowView: 0x7fac67b68550; viewName: RCTScrollView; reactTag: 669; frame: {{0, 108}, {390, 657}}> (tag #669)

Did you find any solution for this? I'm also facing the same issue.
