I'm currently working as full stack developer. I got my first job as an associate software engineer because of Flutter. I have been working with flutter for 3+ years now. Since I'm very comfortable with Flutter and I see lot of newbies work on Flutter projects without following latest standards and good coding practices I thought it would be a good idea to create courses on Flutter that teaches latest standards and clean code. Since BLoC is the most robust and most popular state management solution for Flutter I only use BLoC for all of my projects.
Other tech stacks I'm comfortable and work with - javascript, typescript, nestjs, nextjs, go lang, react, react native, docker, kubernetes, etc.
