Flutter ListView Builder渲染溢出问题求助

我在用ListView Builder时碰到了渲染溢出问题，确认问题出在ListView上。试过用Expanded组件包裹ListView，但没解决。以下是相关代码片段和报错信息：

@override
Widget build(BuildContext context) {
  debugPrint('Exercises in build: $exercises');
  
  return AlertDialog(
    title: const Text('Add Exercise'),
    content: exercises == null
        ? const Center(child: CircularProgressIndicator())
        : exercises!.isEmpty
            ? const Center(child: Text('No exercises found.'))
            : Column(
                mainAxisSize: MainAxisSize.min,
                children: [
                  TextField(
                    controller: widget.controller,
                    decoration: const InputDecoration(labelText: 'Search Exercise'),
                    onChanged: (value) {
                      searchText.value = value;
                    },
                  ),
                  const SizedBox(height: 16),
                  Flexible(
                    child: ValueListenableBuilder<String>(
                      valueListenable: searchText,
                      builder: (context, value, child) {
                        final filteredExercises = exercises!
                            .where((exercise) =>
                                exercise.name.toLowerCase().contains(value.toLowerCase()))
                            .toList();
                        return ListView.builder(
                          shrinkWrap: true, // Ensures proper sizing
                          itemCount: filteredExercises.length,
                          itemBuilder: (context, index) {
                            return ListTile(
                              title: Text(filteredExercises[index].name),
                              onTap: () {
                                widget.controller.text = filteredExercises[index].name;
                                Navigator.of(context).pop();
                                widget.onAdd(filteredExercises[index]);
                              },
                            );
                          },
                        );
                      },
                    ),
                  ),
                ],
              ),
    actions: [
      TextButton(
        onPressed: () {
          Navigator.of(context).pop();
          widget.controller.clear();
        },
        child: const Text('Cancel'),
      ),
    ],
  );
}
