Data Types in Dart

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


              123
            
void main() {
  print(22+33);
}

In Dart, we can join strings:

main.dart


              123
            
void main() {
  print("Name " + "Alex");
}

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

main.dart


              1234
            
void main() {
  // 2 > 1 ?
  print(true);
}

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.

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.

main.dart


              123
            
void main() {
  print("String example " + 44);
}

Everything was clear?
