Flutter Animations Course | Code With Andrea

This repo contains all the projects from my Flutter Animations Course.

The main project for this course is a Flutter habit tracking app, a (simplified) clone of the Streaks App.

Projects structure

The entire course includes four projects:

• Colors / Numbers Game with Implicit Animations: This is located here and covered in section 1
• Flutter Intro Playground: This is located here and covered in section 1
• Flutter Stopwatch App: This is located here and covered in section 2
• Flutter Habit Tracking App: This is located here and covered in sections 3 to 10 (rest of the course)

Note: each commit in this project corresponds to a specific lesson in the course.
