我想以共享的首选项存储对象，该对象中包含一些字段，例如名称，年龄，电话号码等.我不知道如何在共享的首选项中以波动的方式存储对象.

I want to store an object in shared preferences which contains some fields in it like name, age, phone number etc. I don't know how to store an object in shared preferences in flutter.

推荐答案

在保存之前需要将其序列化为JSON，在阅读后需要反序列化

You need to serialize it to JSON before saving and deserialize after reading
