How paste or clear code

Paste code can helpful for Android platform when you can read SMS.

import React, { Component, createRef } from 'react';
import CodeInput from 'react-native-confirmation-code-field';

class App extends Component {
  handlerOnFulfill = code => {
    if (isValidCode(code)) {
      console.log(code);
    } else {
      this.clearCode();
    }
  };

  field = createRef();

  clearCode() {
    const { current } = this.field;

    if (current) {
      current.clear();
    }
  }

  pasteCode() {
    const { current } = this.field;

    if (current) {
      current.handlerOnTextChange(value);
    }
  }

  render() {
    return <CodeInput ref={this.field} onFulfill={this.handlerOnFulfill} />;
  }
}

How it works?

This component consists of:

1. Container <View {...containerProps}/>;
2. Render the "Cells" for the text code inside the container ("Cells" is <TextInput {...cellProps} />);
3. And over this render invisible <TextInput {...inputProps}/>;
4. "Cursor" inside cell is simulated component
