Feature request

At first see #15046 (comment)

Here we have a base64 encoding in native environment and base64 decoding in js environment( and vise versa for sending binary)

This redundant encode/decode take a lot of CPU resources and can be omitted

In https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/react/bridge/WritableMap.java#L21 we only have putString so we cannot transfer binary from native to js or vise versa , I request void putByte(String key, Byte value); method for android and similar method for iOS and JS side

Hey @sm2017! Thanks for opening the issue, however it looks like a feature request. As noted in the Issue template we'd like to use the GitHub issues to track bugs only. Can you implement the feature as a standalone npm module? If not, consider sending a pull request or a creating an entry on Canny. It has a voting system and if the feature gets upvoted enough it might get implemented. Closing this now, thanks for understanding!
