颤音：单击Textformfield将我重定向回到家：

Question

我的应用中的两个位置只有Textformfields。一次进入我的登录小部件，第二位是我的Pinwidget，这是为了设置个人别针。

主页：始终是登录小部件。在那里执行第一个函数redirectifloggedIn，如果您已经登录的共享preferences中设置了标志，则将其重定向到另一个小部件。

在登录窗口小部件中，一切正常工作，但是在Pinwidget中，我一旦单击了我，我就将其重定向到HOMER中。 TextFormfield。

我已经搜索了Google和stackoverflow，也是发现了类似的问题，但没有解决方案。

我已经尝试了具有最终和静态的各种形式的变体，但似乎没有任何作用。

在其他地方，我有DateTimePicker，但是问题不会出现。

我应该补充说，该应用程序的底座是用扑朔迷离的，但已进行了大量修改。
