Imagine you have two toy boxes. If you put them together, you have one big toy box. In math, we use the + operator to add numbers together, like this: But what if we wanted to use + on our ToyBox objects? Wouldn’t it be cool if Dart understood that adding two toy boxes means

Imagine you have a box of toys. Some are cars, some are dolls, and some are building blocks. If you wanted to play a game that only uses cars, you would first check each toy to see if it’s a car, right? In programming, we do the same thing with type matching. Dart is a

Imagine you are having a conversation with a robot. You ask it a question, and it replies. But what if the robot could never hear you? That wouldn’t be fun, right? In programming, we need a way to let our programs “listen” to us. This is called user input. Dart, like other programming languages, allows
