Flutter Example Apps | Code With Andrea

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.

If there are specific apps or projects that you'd like to see implemented in Flutter, hit me up on Twitter or Slack. There's no guarantee that I'll do them, but it's good to keep the ideas flowing. 🙂
