In Dart, multiple inheritance is not directly supported. Dart follows a single inheritance model, which means a class can inherit from only one superclass at a time. However, to address complex scenarios requiring the reuse of code and handling multiple aspects, Dart provides a feature called Mixins.
Mixins in Dart empower developers to significantly enhance code reusability and simulate certain aspects of multiple inheritance. By utilizing mixins, which are fundamental concepts in Dart, you can add behavior to a class without the need for a full-fledged inheritance relationship. This offers a flexible and efficient way to manage complex scenarios in your Dart programs.
In Dart, We can include a mixin using the "with" or "on" keywords followed by the name of the mixin we want to use. Here's a straightforward example to illustrate a class using mixins.
// Using With Keyword
class A extends B with C {
// ···
}
Or
class A extends B with C, D, E {
// ···
}
// Using On keyword
class A{
}
mixin B on A{
}
Let's discuss more about above mentioned keywords
