运行我的本机代码时react-native run-android出现错误。它工作正常。但是在从 git 中获取新的 pullnpm ci并且在我运行之后然后收到这个错误。

在这里我正在创建登录屏幕，我必须在其中输入用户名和密码，在密码字段中我设置了眼睛图标。当输入密码时，密码将被隐藏，单击眼睛图标后，它应该显示真实的字符。我已经提到了我的 XML 和 java 代码。请查看并帮助我解决方案。我需要在 gradle 中添加任何内容吗？请建议。谢谢

有3个数组，在该值中，我必须计算_activityStatus的数量：“ I”（ony I值）。我正在尝试的一种方法是

    StepsStatus :[]

    StepsStatus = StepsVaue.map(StepsVaue => {
          return StepsVaue._activityStatus;
    }); 

我正在StepsStatus中使用所有_activityStatus。现在，我只需要计算自己的价值即可。

currentNextActivity: Array(3)
    0:
    __typename: "CurrentNextActivity"
    _activityName: "FXL_ACT1"
    _activityStatus: "I"
    _maxHoldTime: "60"
    _userName: "tecnotree"

   1:
    __typename: "CurrentNextActivity"
    _activityName: "FXL_ACT2"
    _activityStatus: "I"
    _maxHoldTime: "60"
    _userName: "tecnotree"
    __proto__: Object

    2:
    __typename: "CurrentNextActivity"
    _activityName: "FXL_ACT3"
    _activityStatus: "N"
    _maxHoldTime: "120"
    _userName: null

谢谢
