Hello there, I'm new to the backend development, as I started my coding career in C/C++ and Java before I learn some HTML/CSS JS PHP and SQL. NOW I'm offered a project of and app to be developed in Flutter and I don't know if MySQL would be fine as a database or that firebase is a better option for both security and utility?
Thanks in advance

I recommend you Google Sheets, it's easy to use

Valentina Studio Free is a great tool for working with databases!
I also recommend that you use PostgreSQL as your database as it
has a very simple MIT License which makes it free as in the air you breath.
(Much better than the MySQL License.) Both Valentina and PostgreSQL work
on Windows, macOS, and Linux!
