Reference in Dart

Reference collects the whole course on one page.

In this chapter, you will:

• find the syntax for every topic, in course order
• see which lesson explains each rule in full
• run short reminders of each feature

What each lesson covers:

• Dart Cheat Sheet: The most used Dart syntax from the whole course on one page, one block per chapter, in course order.

This chapter has 1 lesson. Plan on about 12 minutes, with 3 exercises to check what you learned. Every example is real Dart code: change it, run it again and compare the output, which is the fastest way to learn how each feature behaves.

Simple lesson: keep this page open while you build your own Dart programs.
