hi @stianjensen Thanks for reporting! This is an unfortunate miss from my end. I've made a release with linkify declared with a default prop. Should be ok as the instance is shared for renders without this prop. v0.0.18. Let me know if there are any other issues 👍
As of 0.17.0 that was released today, the library does no longer work when you do not provide a custom linkify-it object as a prop.
The problem is that the existing default value that gets set in the constructor gets unset by the getDerivedStateFromProps call here: https://github.com/obipawan/react-native-hyperlink/blob/980b4117928bad092a8eb816c6b09ac8ef43771d/src/Hyperlink.js#L20
A work-around for now is to always pass in the same default value from the outside.
