説明

I am using react-native fs to download the file. The react-native fs uses promises, so until the promise is returned back it keeps other async functions in a queue to execute. For instance, If i start downloading a file then other async functions(such as getting data from local storage) gets blocked. The other async function starts executing only when the download is complete.

any help would be appreciated.

調査方針: This issue reports that using react native fs for file downloads blocks other async operations in React Native. The problem likely stems from the native module's implementation running on the main thread or not using proper background threading. To investigate, review the native download code in RNFSManager (iOS/Android) and the JavaScript wrapper. Check the 27 comments for any identified workarounds or patches. Additionally, consider if the issue can be resolved by moving the download to a background thread or using a different API like fetch with streaming.
