javascript - 在家里我得到那个错误 : The action 'SET_PARAMS' with the payload {"params": {"company" :"Marciello Resto 2"}} was not handled by any navigator

Question

我现在正在使用 React native 导航 5，并且在我的“主页”组件中，我有一个 setParams 可以工作，但我得到了那个错误:

"The action 'SET_PARAMS' with the payload {"params":{"company":"Marciello Resto 2"}} was not handled by any navigator."

我在安卓模拟器上。
感谢大家的帮助!

我相信这个问题与调用 navigation.setParams 有关。当组件正在卸载时。根据 react 导航文档 [0]，

The setParams method lets us update the params (route.params) of the current screen

如果当前屏幕在 setParams 时已经卸载被调用，那么导航器将无法处理它是有道理的。重做你的逻辑，这样你就不会在模糊上设置参数。
