Dart Island

Dart Island

Dart is the language Flutter is written in. Before we build UIs, we learn to speak Dart — variables, control flow, and the object-oriented ideas Flutter widgets are made of.

Variables

Store values in named boxes.

Data Types

Make decisions based on conditions.

if / else

Make decisions based on conditions.

for & while

Repeat actions with loops instead of writing code again.

Functions & Methods

Package reusable logic into named functions and methods.

Classes & Objects

Blueprint & instance — build your own data types.

Inheritance & Polymorphism

Extend, override, and reuse code with parent-child classes.

Abstraction & Encapsulation

Hide complexity, expose only what's needed.

Mixins

Compose behavior by mixing in reusable capability.
