如何在Flutter中更改Y或X轴标签？

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Y轴标签示例'),
        ),
        body: Center(
          child: Container(
            padding: EdgeInsets.all(20),
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Text('图表标题'),
                SizedBox(height: 20),
                Expanded(
                  child: VerticalAxis(
                    labels: [
                      Text('标签1'),
                      Text('标签2'),
                      Text('标签3'),
                    ],
                    child: Container(
                      color: Colors.blue,
                      // 在这里绘制图表
                    ),
                  ),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }
}

class VerticalAxis extends StatelessWidget {
  final List<Widget> labels;
  final Widget child;

  VerticalAxis({required this.labels, required this.child});

  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        Column(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: labels,
        ),
        SizedBox(width: 20),
        Expanded(child: child),
      ],
    );
  }
}
