How to go about making & selling apps for a living?

Hi there,

I've been developing android apps for over 10 years now. I started back in 2013 and have made hundreds if not thousands of apps along the way. Recently, I started experimenting with Flutter & made 4-5 apps using it.

I would like to make & sell apps for a living. I know there are people out there who are earning well by doing this. How can I go about doing this? Any help would be appreciated!

P.S.: You can check my flutter apps here: https://play.google.com/store/apps/dev?id=4662796156958148278

Peace!
