This is a directory of all my open source Flutter apps and projects. I published these as part of my tutorials at CodeWithAndrea.com.

All the entries are categorized as beginner, intermediate, or advanced, based on their complexity and project size.

I plan to expand this collection further and add more example apps in the future.

Note: most projects include a link to the relevant tutorial from my website or YouTube channel.
