Flutter Dev as a Hobby?

I'm in a non-tech career but would like to do app/web dev to play around with code and stay current on how tech works on practice. I have basics in JS, Java, Python from various courses but just not enough to really start shipping anything. Is Flutter a smart place to get started for someone that does not care about profitability/teamwork/etc and would just like to play around with code? Will this lock me out of putting things e.g. on F-Droid? What else would you recommend?
