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’re getting ready for school. You wake up, brush your teeth, get dressed, and eat breakfast. Normally, you do these steps one after the other. Now, what if you could tell your brain:“Do all these things one after another, without repeating ‘I’ each time!” That’s exactly what method cascading does in Dart! Instead of

Have you ever wondered how a computer knows what letters, numbers, and even emojis mean? When you type A, how does the computer understand that it’s an “A” and not some random symbol? The answer is Unicode. Unicode is like a giant language book for computers. It gives every letter, number, and symbol a unique

Imagine you’re writing a secret code on a piece of paper, and you want to keep every symbol and space exactly as you wrote it. But when you type it into a computer, some characters disappear or change! Wouldn’t it be great if you could tell the computer, “Leave my text alone!”? That’s what raw

Imagine you’re writing a letter to your friend, and you want to include their name in it. Instead of writing: “Hello, [friend’s name]!” Wouldn’t it be great if you could just tell Dart to fill in the name for you? That’s exactly what string interpolation does! String interpolation is a fancy way of saying “put

Imagine you have a mystery box. You don’t know what’s inside until you open it! But wouldn’t it be nice if the box had a label telling you what’s inside before you even open it? In Dart, type information works like that label — it tells us what kind of data we are working with.

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
