Stage 12–3 weeks
Dart Fundamentals
- Variables, types, and null safety
- var, final, const — key differences
- Null-aware operators: ??, ?., !
- Functions: named, anonymous, optional parameters
- Collections: List, Set, Map
- Control flow and error handling
Dart Programming
The language that powers Flutter — clean, fast, and built for cross-platform apps.

Overview
Dart is Google's programming language built for building fast, cross-platform applications. It powers Flutter — letting you write one codebase and deploy to Android, iOS, web, and desktop. Dart is strongly typed, null-safe, and deliberately readable. If Flutter is your destination, Dart is the road. This track takes you from syntax to async patterns to Flutter-ready Dart architecture.
Who is this for?
- ✓ Students starting from zero who want structure
- ✓ Self-taught learners who need a clear path
- ✓ Career switchers ready to commit consistently
What can you build?
- CLI tools and scripts
- Backend servers with Dart (Shelf/Frog)
- Flutter mobile apps (after this track)
- Dart packages published to pub.dev
- Data processing scripts

AI Guide
What AI helps with
- ✓ Explaining Dart null safety errors
- ✓ Converting JavaScript patterns to idiomatic Dart
- ✓ Generating Dart class structures from a description
- ✓ Debugging async/await errors
- ✓ Writing unit tests for Dart functions
What AI cannot replace
- ✗ Understanding why Dart patterns exist — learn the language first
- ✗ Generating large amounts of Dart code without reviewing it carefully

Sample Prompts
I am getting this Dart null safety error: [paste error]. Explain what it means and show me two ways to fix it properly.Rewrite this JavaScript class in idiomatic Dart with null safety, a named constructor, and a factory constructor: [paste JS code]Write a Dart class that represents a User with: id (non-nullable), name (non-nullable), email (non-nullable), profilePicture (nullable). Include a factory constructor that parses from JSON and a toJson() method.Career Path
