DataURL sometime it works but sometimes it not showing the data about react-native-signature-canvas HOT 3 OPEN

You can set a prop called key to the SignatureScreen component and update the key every time the dataURL is updated to trigger the re-rendering of the component.

from react-native-signature-canvas.

@YanYuanFE I'm facing this only on android after updating some of the libraries including Webview and react-native.

Changing component props for re-rendering did not work for me. The way i solved it is that I assumed 2 modes for it.

1. editing mode
2. history mode

the usage is like below:

{(editable || signatureHistory) && (
       <Signature
         ref={this.sigPadRef}
         onOK={this.onSignatureOk}
         webStyle={sigPadStyle}
         imageType="image/svg+xml"
         dataURL={signatureHistory}
      />
)}

The point is that if the dataURL is present in the first render its all fine but, if its "" or undefined and then it gets changed into base64, it might not render.

@someAndroidDeveloper Hi, This may be the same problem, you can try to solve it by setting key={your dataURL} in the Signature component
