Translation is ready but I'm having trouble running the project for review (I'm a complete newbie in the Flutter etc. world so I didn't have a dev environment installed before). I'll try looking into this more because it would be useful to check string lengths at least.

I succeeded in launching the app in an emulator today. Finnish is looking good. Hurraah! 🙂
