问题描述
非常感谢您阅读本文 我目前在我的本机项目中遇到问题 老实说，我怀疑问题是由React导航器引起的 请帮助我解决此问题，我必须查看App.tsx中的代码段 我对本机做出了新的反应，我对react stack navigator遇到了问题 我强烈怀疑问题出在resultScreen.tsx
---------
The action 'NAVIGATE' with payload {"name":"Result","params":{"searchText":"Jane"}} was not handled by any navigator.
Do you have a screen named 'Result'?
If you're trying to navigate to a screen in a nested navigator,see https://reactnavigation.org/docs/nesting-navigators#navigating-to-a-screen-in-a-nested-navigator.
This is a development-only warning and won't be shown in production.
