探索未来文本编辑的可能：Flutter Markdown 编辑器

import 'package:flutter/material.dart';
import 'package:flutter_markdown/flutter_markdown.dart';
 
void main() => runApp(MyApp());
 
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MarkdownEditorScreen(),
    );
  }
}
 
class MarkdownEditorScreen extends StatefulWidget {
  @override
  _MarkdownEditorScreenState createState() => _MarkdownEditorScreenState();
}
 
class _MarkdownEditorScreenState extends State<MarkdownEditorScreen> {
  final _controller = TextEditingController();
 
  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Markdown Editor'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          children: <Widget>[
            Expanded(
              child: TextField(
                controller: _controller,
                maxLines: null,
                decoration: InputDecoration(hintText: 'Enter Markdown'),
              ),
            ),
            SizedBox(height: 16.0),
            Expanded(
              child: Markdown(
                data: _controller.text,
                selectable: true,
              ),
            ),
          ],
        ),
      ),
    );
  }
}

这段代码创建了一个简单的Markdown编辑器，用户可以在上面输入Markdown格式的文本，并实时预览。这个例子展示了如何在Flutter应用中整合Markdown解析器，并使用TextField来接收用户输入。
