Booleans

Let’s go over the boolean data type in Dart.

We'll cover the following

True & false

Dart’s bool type represents boolean values. Only two objects have type bool, the boolean literals true and false.

In the code snippet below, we are declaring a variable b1 of type bool and assigning it an initial value of true.

main() {
  bool b1 = true;
  print(b1);
}

Syntax

The basic syntax for declaring a variable of type bool is as follows.

bool variableName = Boolean Literal

This is all you need to know regarding bool for now. You will see more if its use when we discuss operators and conditional statements in later chapters.

main() {
  bool greater;
  greater=5>3;
  print(greater);
}
