Edit string in Flutter

I am developing a flutter app using the Jitsi SDK.
(Use: https://pub.dev/packages/jitsi_meet)

Some Korean strings are wrong.
So I registered the issue.

Registered a pull request to resolve the issue.

It is difficult to provide a service with the currently translated strings.
Please let me know if there is a way to change the string.
Thank you.
