This is pretty much what https://pub.dev/packages/recase offers. And I'd love to have them provided by dartx.

I don't mind, having the functionality duplicated here. But I have some questions I personally don't yet have answers to:

• Instead of implementing it again, could we just export recase?
• Why methods, not getters?
• Should those methods end with Case, i.e. snakeCase()?

👍 for better documentation than recase 😉

Recase is highly used right now.

Let's just use the same convention that most people are used to.

Can we just export it like @passsy said?
