Show API errors in toast

At the moment, if we have an error when requesting something from the API, for example when searching, this is not handled in any way and the error is not shown. There is a suggestion to show an error in [toast](https://github.com/magicismight/react-native-root-toast). Or does anyone have any other thoughts on this matter?

未指定文件、测试或入口点。从搜索开始跟踪 API 请求路径，并检查当前如何处理失败。确认 react-native-root-toast 是否是预期的依赖项，然后定义受影响的错误情况，并验证每种情况都会显示适当的 toast。
