Question

我的本机条形码只显示黑色全黑条。

我已经完成npm install react-native-svg --save && react-native link react-native-svg

下面是我的代码

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';

import Barcode from 'react-native-barcode-builder';

export default class Example extends Component {
  render() {
    return (
      <View>
        <Text>
          React Native Barcode Builder
        </Text>
        <Barcode value="Hello World" />
      </View>
    );
  }
}

我希望我能得到正常的条形码而不是全黑

像这样将背景色设置为白色：

<Barcode value="Hello World" background="#ffffff" format="CODE128" />
