为不同的输入反应原生动态输入形式相同的值

如何解决为不同的输入反应原生动态输入形式相同的值

我刚刚开始使用 React Native 学习 JS，我想使用 firebase firestore 构建一个应用程序。

但是我遇到了一个问题——当用户想要上传帖子时，他应该能够上传他的名字、他的头衔、他的年龄和他的队友（他的队友应该是嵌套对象并且应该有：姓名、 Title,Age) - 用户应该能够为每个新队友添加动态输入字段，这些字段应该将数据添加到 firestore（每个队友应该包含在索引从 0 开始的对象/地图中，并且在里面他们应该为每个队友输入姓名、职位和年龄）。

我设法解决了所有这些问题，除了一个。我找到了如何从一些 tuts 在线添加动态输入并设法将其连接到 firebase。但只有一个属性（比如名称）而不是其他属性。

当我尝试为用户添加不同的输入（每个新队友的头衔/年龄）时，他们会自动完成第一个输入的信息。我知道这对我来说是一个错误，因为我并不真正了解这些功能是如何工作的，以及由于我的专业知识水平较低，如何使它们适应我的需求。

如果你能帮忙就好了。谢谢。

这里是用于队友（姓名、职位、年龄）的多个输入的代码，这些输入不起作用且不知道如何使其起作用。
