flutter - 使用 Dart 将字符串转换为列表/映射

问题描述

我正在尝试将 outerHTML 转换为 JSON 如何转换此字符串

<tr>
                     <td>00001</td>
                     <td>ADVANCE DATABASE MANAGEMENT SYSTEM [A]</td>
                     <td>Open</td>
                     <td>40</td>
                     <td>37</td>

                     <td><table class="table table-condensed table-bordered"><tbody><tr><td>Theory </td> <td>Sunday </td> <td>8:00 AM </td> <td>10:00 AM </td> <td>1113 </td></tr><tr><td>Lab </td> <td>Tuesday </td> <td>8:00 AM </td> <td>11:00 AM </td> <td>D0202 </td></tr></tbody></table></td>
                 </tr>

使用 Dart/Flutter 像这样进入 List 或 Map

{
    "class id": "00001",
    "title": "ADVANCE DATABASE MANAGEMENT SYSTEM [A]",
    "status": "Open",
    "capcity": "40",
    "count": "37",
    "time": {
        "Theory": {
            "day": "Sunday",
            "start": "8:00 AM",
            "end": "10:00 AM",
            "location": "1113"
        },
        "Lab": {
            "day": "Tuesday",
            "start": "8:00 AM",
            "end": "11:00 AM",
            "location": "D0202"
        }
    }
},

import 'package:html/parser.dart' show parse;
