Dart Cascade Notation

Cascade notation, denoted by the .. operator in Dart, allows you to perform a sequence of operations on the same object without having to repeat its name. It's particularly useful when you need to invoke multiple methods or setters on an object consecutively.

Basic Syntax :

object..method1()
..method2()
..property1 = value1
..property2 = value2;

Example

class Person {
String name;
int age;
Person(this.name, this.age);
void introduceYourself() {
print("Hello, my name is $name and I'm $age years old.");
}
}
void main() {
var person = Person("Alice", 30);
// Without cascade notation
person.name = "Bob";
person.age = 25;
person.introduceYourself();
// With cascade notation
person
..name = "Charlie"
..age = 40
..introduceYourself();
}
