React-Native-Signature-Capture-View

Capture signatures in react native

A webview wrapper over signature_pad.js. This is fully javascript based component so no linking is required.

Made this component for a client project. Decided to open source it since its already internally using signature_pad.js

import {SignatureView} from 'react-native-signature-capture-view';

const App = () => {
  const signatureRef = useRef(null);
  const [text,setText] = useState('')
  return (
    <>
      <StatusBar barStyle="dark-content" />
      <SafeAreaView style={{ flex: 1}}>
        <SignatureView
        style={{

          height:200,
        }}
        
          ref={signatureRef}
          // onSave is automatically called whenever signature-pad onEnd is called and saveSignature is called
          onSave={(val) => {
            //  a base64 encoded image
            console.log('saved signature')
            console.log(val);
            setText(val)
