Flutter Zero to Mastery

Write code from lesson one

Every lesson is an exercise you solve in your browser. Real code, real tests, real feedback.

Write a greeting function

main.ts

function greet(name: string) {

return `Hello, ${name}!`

}

Structured progression

Each concept builds on the last. You always know what to learn next.

Multiple exercise types

Quizzes, fill-in-the-blank, matching, and code keep every lesson engaging.

Instant feedback

Submit your answer and see test results in milliseconds.

Learn by doing

Solve exercises in your browser from the first lesson.

What you'll gain

Think like an engineer

Every course trains problem-solving through real exercises.

Understand the principle

// One class doing everything...

class UserManager {

fetch() validate() cache() notify()

}

Understand the why

Every lesson explains the principle, then makes you apply it. You learn how things work — and can adapt when things change.

AI prompt

Refactor fetchUsers to follow the single responsibility principle. It currently handles fetching, caching, and error mapping.

Split into three functions. Keep the return type as Result<User[]>.

Response

// 1. Fetch responsibility

async function fetchUsers() {

// 2. Cache responsibility

function cacheUsers() {

// 3. Error mapping

function mapErrors() {

Direct AI with confidence

S.O.L.I.D. and D.R.Y. give you the vocabulary to review, refine, and ship what AI generates.
