Localizing jitsi flutter plugin

Hi there, I’m new to jitsi (kudos for the team) but I managed to install jitsi server on ubuntu and it’s working fine. Then I added the flutter jitsi plugin to an existing flutter app, which is also working fine, but I just can’t find a way to change the interface language from english to portuguese, as I did for the server. Wondering if anyone here could show me the way.
