Imports, Exports, and Libraries

Organize and re-export your code.

What an Import Does

An import pulls another file or package into your code so you can use its classes and functions. Every Dart file starts with them. 📥

import 'dart:math';

Built-in libraries use the dart: prefix. For example, dart:math gives you sqrt and Random without installing anything.

import 'dart:convert';
