根据Flutter文档，ExpansionPanelList小部件不提供直接自定义选项。
1.您可以通过使用ListView或Column Package ExpansionPanelList来对其进行自定义。

这里有一个例子，你可以试试：

ListView(
  children: [
    // Add any custom widgets or padding here
    ExpansionPanelList(
      // Expansion panel configuration
      expansionCallback: (int index, bool isExpanded) {
        // Handle expansion
      },
      children: [
        // Expansion panels
      ],
    ),
    // Add any custom widgets or padding here
  ],
)

1.您可以使用ExpansionPanel小部件。通过这样做，您还可以完全自定义和控制扩展行为。

这里有一个例子，你可以试试：

class CustomExpansionPanelList extends StatelessWidget {
  final List<CustomExpansionPanel> children;

  CustomExpansionPanelList({required this.children});

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        // Add any custom widgets or padding here
        for (var panel in children)
          panel,
        // Add any custom widgets or padding here
      ],
    );
  }
}

class CustomExpansionPanel extends StatefulWidget {
  // Custom properties and constructor

  @override
  _CustomExpansionPanelState createState() => _CustomExpansionPanelState();
}

class _CustomExpansionPanelState extends State<CustomExpansionPanel> {
  bool _isExpanded = false;

  @override
  Widget build(BuildContext context) {
    return ExpansionPanel(
      // Expansion panel configuration
      isExpanded: _isExpanded,
      headerBuilder: (context, isExpanded) {
        // Header content
        // Add any custom styling for the header when not expanded
      },
      body: Container(
        // Body content
        // Add any custom styling for the body when expanded
      ),
      canTapOnHeader: true,
      onExpansionChanged: (isExpanded) {
        setState(() {
          _isExpanded = isExpanded;
        });
      },
    );
  }
}

我希望这可以帮助您构建或自定义ExpansionPanelList。
