TextInput accepts only numbers - React Native

rn.input-numbers.js

import React, { Component } from 'react';
import { TextInput } from 'react-native';

class Input extends Component {
    constructor(props) {
    super(props);
    this.state = {
      text: ''
    };
  }

   handleInputChange = (text) => {
    if (/^\d+$/.test(text)) {
      this.setState({
        text: text
      });
    }
  }
   
  
  render () {
    return (
      <TextInput
        keyboardType='numeric'
        onChangeText={this.handleInputChange}
        value={this.state.text}
      />
    )
  }

}

Nice snippet, I tried the code and discovered a bug though. You can't set the text back to blank. Here is how i changed the code

if (/^\d+$/.test(amount) || amount === '') { this.setState({ amount }) }

Great, this works excellent

Thanks
