Same here.

Let me know if you find any solution please. I'll do the same if a solve this.

[trevor-coleman]

Is this on android or iOS? And are you running on device or in a simulator?

[mswat5]

try to run it with development build, expo go doesn't support native modules @shehanGuruge @niloriver

[alexis791]

Hey @mswat5 @trevor-coleman @shehanGuruge @niloriver! I already ran a development build, but I got the same result.

Cannot find native module 'RNMLKitDocumentScanner'

Did you find a way to solve it?

[trevor-coleman]

Are you trying to run it on iOS or Android? Document scanner is not supported on iOS.

[frankcalise]

This library cannot be used with Expo Go. Please use development builds.

Although not the original poster, the document scanner can also only be used on Android as per the Google APIs currently. This is not our doing, it's the only platform available for it right now
