For flutter .arb files. Preferably open source and low cost.
Also side question: how do you properly keep track of and credit translators?
Weblate. You can use the instance from Codeberg.org if your project is open-source.
Can I still use it if my project is on GitHub?
Should be possible yeah, but I think the official weblate instance is better set up for github.
Oh didn’t even notice weblate had a free option I just clicked off when I saw 45$ on the cheapest tier
Yeah, free for open-source projects or so. Never used it though as I either use the Codeberg one or a self-hosted one I recently set up. But for a small project I would not recommend self-hosting it as it is surprisingly heavy on server resources.
I do not know if the solutions I listed below are open source ; however as an open source contributor I am used to work with some tools depending to choice of the projects:
About credits, I don’t think these tools exposes in some automated way the contributors identities. However, nothing prevents you to use these web UI tools to find who contributed and list people for example in your CONTRIBUTORS files. Another way could be to edit the automated commits these tools submit to your Git repos by adding credits to the translators (with for example Co-authored-by field).
