There was a problem hiding this comment.
This has changed from a Data URI to a File URI with a mimetype, which requires some minor changes but is mostly simpler (i.e. no need to do regex mime type nonsense except on web)

That one ^^^ is a little out of date so I used Expensify's patch for reference, as it's for 0.81.4 (still required me to manually reapply though as we're on 0.81.5 😢): https://github.com/Expensify/App/blob/main/patches/react-native/react-native%2B0.81.4%2B011%2BAdd-onPaste-to-TextInput.patch
Android required some further tweaks, like more accurate mime type detection and copying the content uri to a file uri
This lets us get rid of Mattermost's paste input library, yay!
Caveat: we now have to compile RN from source on Android
