[!WARNING] 使用时 import 的库名不变。 [!TIP] 当报错信息为Property 'TextEncoder' doesn't exist解决方案

import {  Text, View } from "react-native";
import QRCode from 'react-native-qrcode-svg';

export const SvgDemo = () => {
    return (
        <View style={{ flex: 1, backgroundColor: '#FFFFFF' }}>
            <QRCode
                size={300}

            />
        </View>
    )
}

本库 HarmonyOS 侧实现依赖@react-native-oh-tpl/react-native-svg 的原生端代码,如已在 HarmonyOS 工程中引入过该库,则无需再次引入,可跳过本章节步骤,直接使用。

如未引入请参照@react-native-oh-tpl/react-native-svg-capi 文档的 Link 章节进行引入
