What is a variable?
A variable is a named box that stores a value so you can use it later. In Dart, you declare a variable with a type, a name, and a value:
String heroName = "Ada";
int age = 28;
bool isReady = true;
- String → text, always wrapped in quotes (e.g. "Ada")
- int → whole numbers, no quotes (e.g. 28)
- bool → only true or false
Now try the six mini-games below to practice matching, naming, and writing variables yourself.
