Introduction to Dart

Data types

What are data types?

Dart supports different data types for different tasks. Like in life, we use words to communicate and numbers to calculate.

Dart allows us to use numbers for mathematical operations:

main.dart

In Dart, we can join strings:

main.dart

We can use the bool data type to print whether a statement is true or false:

main.dart

In the future, we will learn to work with all types of data, and in the following chapters we will consider the simplest of them.

What are the differences between data types?

For example, we can perform mathematical operations between int and double because both are numbers.

Note
int and double are numbers, but the int data type does not store decimals, so it can only store integers. But the double can store any number.

However, we cannot add a String to an int or double because a String is simply a sequence of characters, which does not support mathematical operations.
