Flutter & Dart for Beginners: 50 Exercises, No Setup Needed

This course contains the use of artificial intelligence.
Designed for those who want to start Flutter but keep putting it off because setting up the environment feels like a hassle.

Since this course uses an online editor that runs entirely in your browser, there's zero installation required. Close this page and you can start the very first exercise right away.

What you'll learn

Starting from Dart language basics, you'll progressively master Flutter's Widgets, layouts, state management, navigation, and HTTP communication — through 10 sections and 50 hands-on exercises.

Each exercise isn't just watching a video and copying code. You'll complete starter code with intentional gaps, then verify your results live in DartPad's preview. The course is designed around the feeling of being able to write code yourself — something you simply can't get from just reading.

In the second half of the course, you'll build 5 mini apps including a Todo list, weather app, and Pomodoro timer. Finished code can be shared via DartPad URLs, making it easy to review each other's work.

Who this course is for

• Complete beginners with no prior Flutter or Dart experience

• Anyone who feels nervous about getting stuck on environment setup

• Learners who want to write code themselves, not just watch videos

• Developers experienced in JavaScript, Python, or other languages, but new to Flutter

Requirements

All you need is a browser with an internet connection. No Flutter or Dart installation required.

Curriculum overview

Sections 1–3: Dart fundamentals (Q1–Q15) Build the Dart foundation you need before writing Flutter — variables, types, control flow, functions, and classes. Output is verified with print(), making it approachable even for first-time programmers.

Sections 4–5: Flutter Widgets and layouts (Q16–Q25) Learn core Widgets like Text, Container, and Image, then master screen layout using Column, Row, and Stack.

Section 6: StatefulWidget and setState (Q26–Q30) Practice the fundamentals of state management — one of Flutter's most important concepts — through hands-on exercises with counters, text inputs, and sliders.

Sections 7–8: List UIs and navigation (Q31–Q40) Build app-style list screens with ListView and GridView, then learn to navigate between multiple screens using Navigator. You'll also implement BottomNavigationBar and Drawer.

Section 9: Async programming and HTTP (Q41–Q45) Use async/await and FutureBuilder to fetch JSON data from the internet and display it on screen. Error handling is covered thoroughly.

Section 10: Mini app capstone exercises (Q46–Q50) Bring everything together by completing 5 mini apps: a Todo list, weather app, Pomodoro timer, BMI calculator, and business card app — all ready to use as portfolio pieces.

About difficulty levels

Exercises are divided into three levels: beginner, intermediate, and advanced. Beginner exercises are designed so that complete newcomers can solve them right away. Intermediate and advanced exercises come with detailed explanations and solution code, so you can always look at the answer to deepen your understanding and keep moving forward without getting stuck.

By the end of this course

You'll have the skills to build a simple Flutter app from scratch. Having solved 50 exercises with your own hands — not just passively watched videos — gives you the real confidence to take the next step: building your own app or diving into more advanced state management.
