文字溢出颤音

Question

我有下一个小部件，它呈溢出。我试图解决，但我不知道。谁能帮我吗？目的是在ListView中进行自定义卡。 当时我试图用扩展的Buth包裹，该错误是通过约束所引用的。

    import 'package:flutter/material.dart';

     import '../../shared/AppTheme.dart';

     class ComandaScreen extends StatefulWidget {
      const ComandaScreen({Key? key}) : super(key: key);

     @override
     State<ComandaScreen> createState() => _ComandaScreenState();
      }

      class _ComandaScreenState extends State<ComandaScreen> {
      bool expanded = false;
      int unidades = 0;

        final List<Map<String, dynamic>> _items = List.generate(
       10, (index) => {'id': index, 'Nombre': 'Nuggets $index', 
       'isExpanded': false, "unidades": 8});

      @override
      Widget build(BuildContext context) {
    final ButtonStyle flatButtonStyle = TextButton.styleFrom(
      shape: const RoundedRectangleBorder(
        borderRadius: BorderRadius.all(Radius.circular(4.0)),
      ),
    );

    return Scaffold(
      appBar: AppBar(
        title: const Text('Comanda'),
        backgroundColor: AppTheme.backgroundColor,
        foregroundColor: AppTheme.primaryTextColor,
        elevation: 0,
      ),
      body: SingleChildScrollView(
        child: ExpansionPanelList(
          elevation: 3,
          // expandedHeaderPadding: const EdgeInsets.all(10),
          expansionCallback: (index, isExpanded) {
            setState(() {
              _items[index]['isExpanded'] = !isExpanded;
            });
          },
          animationDuration: const Duration(milliseconds: 200),
          children: _items
              .map(
                (item) => ExpansionPanel(
                  canTapOnHeader: true,
                  // backgroundColor: item['isExpanded'] == true ? Colors.cyan[100] : Colors.white,
                  headerBuilder: (context, isExpanded) {
                    return Container(

我编辑了代码以显示所有屏幕窗口小部件。

对于桌面应用程序，您可以通过断点进行调整大小，因此不会发生错误。在pubsec.yaml文件中，添加以下依赖关系。

window_size:
    git:
      url: https://github.com/google/flutter-desktop-embedding.git
      path: plugins/window_size

在您的主要方法中，在runapp添加此代码之前，该代码在该应用程序无法调整大小的情况下以最小宽度和最小高度添加。

const double desktopMinWidth = 800.0;
const double desktopMinHeight = 600.0;

if (Platform.isMacOS || Platform.isWindows) {
    setWindowMinSize(const Size(desktopMinWidth, desktopMinHeight));
    setWindowMaxSize(Size.infinite);
}

注意：完成后重新启动您的应用程序。

对于移动设备，这完全是不同的情况。您可能需要重组设计
