react native pathjs charts crashes in iPone simulator

• I have searched for existing issues
• I have provided detailed instructions that can reproduce the issue (including code and data necessary)
  In preparation for using this package, I was able to clone the repo and successfully run the example on my Mac-mini.
  However as a trial I added one of the example pages (StockLineChartBasic) to my app just to get the feel of the package. My app uses react-native-router-flux for navigation. As soon as I navigate into the new chart page, the app crashes with the stack trace below. I would dearly love to use this charting functionality in my app, so would appreciate any pointers on debugging this problem.

I'm not entirely sure how one reproduces this, but it appears that maybe related to using react-native-svg (which this lib depends on) + some other libs like ART (as mentioned in software-mansion/react-native-svg#246) or react-native-progress (as mentioned in oblador/react-native-progress#40 (comment)).

Looks like it may be a react-native-svg issue rather an issue with this lib. However, I'd like to understand what the root cause is in case someone us comes here with a similar issue in the future. From reading the comments on those two issues, it seems like several people are blocked on this.

Maybe you could find versions for your dependencies:

npm list react-react-native react-native-svg

and provide this info and discuss with others on those existing react-native-svg issue threads to see if you can come up with something in common that could lead to determining root cause?

Thanks for responding so promptly.
Here is the output of the npm list command:

I am not sure what it means when it reports 2 versions of react-native-svg as above. Could that be the problem?

[marzolfb]

It's possible. Change your version spec in your root package.json for react-native-svg to not go above 4.5.x and then re install the lower version

Hi, Just confirming i had the same issue with the following
├─┬ [email protected]
│ └── [email protected]
└── [email protected]

Downgrading [email protected] has fixed it and everything seems to be working fine

[balaskumar]

Once I went back to svg 4.5, things started working very well.
Thanks to both of you!

I just ran into this problem and downgrading the react-native-svg version to 4.5.0 fixed the issue. Might be worth noting in the Readme?
