如何在flutter中定位不同屏幕尺寸的文本控件？

import 'package:flutter/material.dart';

class ResponsiveText extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return LayoutBuilder(
      builder: (context, constraints) {
        double fontSize = constraints.maxWidth > 600 ? 24 : 16;
        return Text(
          'Hello, Flutter!',
          style: TextStyle(fontSize: fontSize),
        );
      },
    );
  }
}

import 'package:flutter/material.dart';

class OverflowText extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return OverflowBox(
      minHeight: 0,
      maxHeight: double.infinity,
      child: Text(
        'This is a very long text that should not be truncated on small screens.',
        softWrap: true,
      ),
    );
  }
}
