[hoangminhan]

react-native version【0.70.9】
react-native-webview 【13.6.0】
Platform【android and ios】

I'm using template literals with span tag. when i use template literals, chart content doesn't show

formatter:function (params) {
              let content =
                '<strong>' + params[0].name + '</strong>' + '<br />';
              let total = 0;

              params.forEach(function (item) {
                const seriesValue = item.value;
                const seriesValueTotal = item.seriesName.includes('Belink')
                  ? item.value
                  : 0;
                total += Number(seriesValueTotal);

                content +=
                  `<span style="width:6px;height:6px;color:${item.seriesIndex};display:inline-block"></span>` +
                  item.seriesName +
                  ': ' +
                  seriesValue.toLocaleString('en-US') +
                  '<br />';
              });

              // Display the total at the end of the tooltip
              content +=
                '<strong>Tổng sản lượng: </strong>' +
                total.toLocaleString('en-US');

              return content;
            }

• Did you use enableParseStringFunction props? enableParseStringFunction
• Please show minimum reproducible demo, like this:

import React from "react";
import { View } from "react-native";
import RNEChartsPro from "react-native-echarts-pro";

export default function RNEPDemo() {
  const pieOption = {
    series: [
      {
        name: "Source",
        type: "pie",
        legendHoverLink: true,
        hoverAnimation: true,
        avoidLabelOverlap: true,
        startAngle: 180,
        radius: "55%",
        center: ["50%", "35%"],
        data: [
          { value: 105.2, name: "android" },
