Outdated

Having a hard time getting this to run in the latest version of Expo. I tried updating the packages, but am getting an "unsupported version of Expo (SDK 10.0.0) error.

This example works great by itself but when I try to bring the code into my expo app, the signature is off by about 100px vertically, I sign but it draws about 100px below my finger. And then the paths don't save. Any chance it could be updated to use the latest version of expo?

The signature being off by 100px had to do with a compatibility issue with React Navigation. Still trying to figure out why the paths don't save. Is there some HOC involved in this that would make that not work?

@brentvatne Any chance you know why this example seems to only work using the expo @expo/ex-navigation? This is the only signature pad example I can find that doesn't require using a native library (aka the only example that will work with expo), and it works fantastic, until you try to use it with React Navigation or React Router Native.

Hi @chongdog83 - I don't have time to maintain this and I'm no longer familiar with the code. I updated the repo description accordingly:

OUTDATED - this repo is not maintained and will not work as-is if you clone it. The underlying technique should still work but you will have to read the code to understand

If you come up with a solution that works in all environments I'd be happy to redirect people to your repo/post/whatever with that information!

Figured it out, in SignatureView.js, line 96, change it to this and it will work with newer versions of Expo

        { this.state.donePaths.map((donePaths, index) => {
            return (
              <Svg.Path
                key={donePaths.key}
                d={donePaths.props.d}
                stroke="#000000"
                strokeWidth={4}
                fill="none"
              />
            );
        })
      }
