}

调用时需要传入BuildContext context

.onTap(() {controller.showImagePicker(BuildContext context);
}),/ 定义选项列表
final List<Map<String, dynamic>> actions = [{"id": 1, "title": "相机", "type": "camera"},{"id": 2, "title": "相册", "type": "gallery"},
];// 在控制器或页面中使用
void showImagePicker(context) async{ActionSheetUtil.showActionSheet(context: context,title: '请选择',items: actions,onConfirm: (item) async {print('操作类型：${item['type']}');},);
}
