[React Native] "Setting a timer for a long period of time" warning

描述

 WARN  Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info.

研究方向

The warning occurs at https://github.com/facebookexperimental/Recoil/blob/master/src/hooks/Recoil Hooks.js#L60 due to a long timer. The fix involves replacing the timer with a React Native friendly approach, such as using InteractionManager.runAfterInteractions or a native module. Review the React Native issue linked (facebook/react native#12981) for guidance on avoiding this warning. The change is localized to a single file.
