Data Types in Dart
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
123void main() { print(22 + 33); }
In Dart, you can join strings:
main.dart
123void main() { print("Name " + "Alex"); }
You can use the bool data type to print whether a statement is true or false:
main.dart
1234void main() { print(true); print(false); }
For example, you can perform mathematical operations between int and double because both are numbers.
Both int and double represent numbers. Use int for whole values like counts or years, and double for values with decimals such as prices or measurements.
However, you cannot add a String to an int or double because a String is simply a sequence of characters.
main.dart
123void main() { print("String example " + 44); }
