#Dart Complete Course — Zero to Professional

Learn the Dart language from absolutely nothing to professional level. No programming experience required. Pure Dart — no Flutter.

Video lectures are being recorded now. Each lecture is published here first as a written article — all the code, the expected output, practice questions, and worked answers — and the matching video link is added to the table below as it goes live.

#Who This Course Is For

• Complete beginners. If you have never written a line of code, start at Lecture 001.
• Fresh graduates preparing for a job — Dart is the language behind Flutter, the most widely used cross-platform app framework.
• Developers from another language who want Dart specifically. Skim the early categories and slow down from Null Safety (Category 3) onward.

What you need before Lecture 001: a computer, an internet connection, and the willingness to type the examples out yourself. Nothing else — Lecture 002 installs everything.

#What You Will Be Able To Do

By the end of this course you will be able to:

• Write, run, and debug Dart programs from the command line
• Use Dart's type system and null safety with confidence
• Work fluently with collections, functions, and object-oriented design
• Handle errors, asynchronous code, streams, and isolates
• Read and write files and JSON, and call APIs over HTTP
• Write unit tests and use the analyzer, formatter, and DevTools
• Build a complete Dart project from scratch (Category 23)
• Move on to Flutter without the language getting in your way

#How To Use This Repository

1. Install Dart — full walkthrough in Lecture 002.

dart --version   # confirm it is installed

2. Get the code

git clone https://github.com/USER/REPO.git
cd REPO

3. Run any example. Copy a program from a lecture into a file and run it:

dart run my_example.dart

4. Do the practice questions before reading the answers. Every lecture ends with practice questions and fully worked solutions. The learning happens in the gap between the two.

Every code example and every error message in these articles was produced by actually running the code on Dart 3.12. If an article says a program prints 50.0, it prints 50.0.

#Every Lecture Follows The Same Structure

1. Introduction and learning objectives
2. Prerequisites and connection to previous lectures
3. Simple explanation using beginner-friendly language
4. Real-world analogy when useful
5. Syntax and fundamentals
6. 8–10 meaningful code examples of progressive difficulty
7. Expected output and line-by-line explanations
8. Common mistakes, with the real error messages Dart produces
9. Best practices
10. 8–10 practice questions (beginner → application → challenge)
11. Practice answers and outputs, shown only at the end
12. Key takeaways and next-lecture preview

#Course Standards

• Written for complete beginners, and kept understandable to learners outside software development.
• Technical correctness is based on current Dart 3.x behavior (recorded on 3.12).
• Explanations prioritize simple language, relatable examples, gradual complexity, and practical problem solving.
• The sequence is prerequisite-driven: a concept appears only after everything needed to understand it.
• Practice questions progress from beginner → application → challenge, and solutions never sit next to their question.
• The final project comes after modern Dart topics, so students apply the whole language in a logical sequence.
