项目没法跑起来，依赖的版本可能是不对的？

1. 克隆了仓库
2. 执行了：

flutter pub get

但是发现执行完毕后，pubspec.lock 文件发生了变更，并且 lib/components/markdown.dart 文件中也提示某些属性不受支持：
2.1 执行 flutter pub get 后文件的变更：

(base) ➜  flutter_chat_box git:(main) ✗ git status
On branch main
Your branch is up to date with 'origin/main'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   macos/Flutter/GeneratedPluginRegistrant.swift
        modified:   pubspec.lock

2.2 markdown.dart 中提示的不支持的属性：

修改了一下 makrdown：

import 'package:flutter/material.dart';
import 'package:flutter_chatgpt/components/code_wrapper.dart';
import 'package:flutter_chatgpt/components/latex.dart';
import 'package:markdown_widget/markdown_widget.dart';

class Markdown extends StatelessWidget {
  final String text;
  const Markdown({super.key, required this.text});

  @override
  Widget build(BuildContext context) {
    final isDark = Theme.of(context).brightness == Brightness.dark;
    final config =
        isDark ? MarkdownConfig.darkConfig : MarkdownConfig.defaultConfig;

    CodeWrapperWidget codeWrapper(Widget child, String text, String language) {
      return CodeWrapperWidget(child: child, text: text);
    }

    return SelectionArea(
      child: Padding(
        padding: const EdgeInsets.all(8.0),
        child: Column(
            mainAxisAlignment: MainAxisAlignment.start,
            crossAxisAlignment: CrossAxisAlignment.start,
            children: MarkdownGenerator(
              inlineSyntaxList: [LatexSyntax()],
              generators: [latexGenerator],
            ).buildWidgets(
              text,
              config: config.copy(configs: [
                isDark
                    ? PreConfig.darkConfig.copy(wrapper: codeWrapper)
                    : const PreConfig().copy(wrapper: codeWrapper),
                TableConfig(
                    wrapper: (table) => SingleChildScrollView(
                          scrollDirection: Axis.horizontal,
                          child: table,
                        )),
              ]),
            )),
      ),
    );
  }
}

flutter 层面没报错了，但是 iOS 方面有个报错：

我也遇到了你的问题，感谢你修改了 makrdown
