当用户在其显示设置中更改文本大小时，我的flutter应用程序的文本大小也会发生变化，这会干扰附近的小部件

import 'package:flutter/material.dart';

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final double textScaleFactor = MediaQuery.of(context).textScaleFactor;

    return LayoutBuilder(
      builder: (context, constraints) {
        // 根据 textScaleFactor 调整文本大小
        double fontSize = 16 * textScaleFactor; // 假设默认字体大小为 16

        return Text(
          'Hello, Flutter!',
          style: TextStyle(fontSize: fontSize),
        );
      },
    );
  }
}

import 'package:flutter/material.dart';

class MyWidget extends StatefulWidget {
  @override
  _MyWidgetState createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  double _textScaleFactor;

  @override
  void initState() {
    super.initState();
    _textScaleFactor = MediaQuery.of(context).textScaleFactor;
  }

  @override
  Widget build(BuildContext context) {
    // 使用存储的 textScaleFactor 设置文本大小
    double fontSize = 16 / _textScaleFactor; // 假设默认字体大小为 16

    return Text(
      'Hello, Flutter!',
      style: TextStyle(fontSize: fontSize),
    );
  }
}

import 'package:flutter/material.dart';

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Text(
      'Hello, Flutter!',
      style: TextStyle(fontSize: 16), // 手动设置字体大小
    );
  }
}
