The static keyword is used to declare the class variable and method. It generally manages the memory for the global data variable. The static variables and methods are the member of the class instead of an individual instance. The static variable or methods are the same for every instance of the class, so if we […]
The this keyword is used to refer the current class object. It indicates the current instance of the class, methods, or constructor. It can be also used to call the current class methods or constructors. It eliminates the uncertainty between class attributes and the parameter names are the same. If we declare the class attributes […]
A constructor is a different type of function which is created with same name as its class name. The constructor is used to initialize an object when it is created. When we create the object of class, then constructor is automatically called. It is quite similar to class function but it has no explicit return […]
Dart classes are the blueprint of the object, or it can be called object constructors. A class can contain fields, functions, constructors, etc. It is a wrapper that binds/encapsulates the data and functions together; that can be accessed by creating an object. A class can refer to as user-define data type which defines characteristics by […]
Dart is an object-oriented programming language, and it supports all the concepts of object-oriented programming such as classes, object, inheritance, mixin, and abstract classes. As the name suggests, it focuses on the object and objects are the real-life entities. The Object-oriented programming approach is used to implement the concept like polymorphism, data-hiding, etc. The main […]
Dart Recursion is the method where a function calls itself as its subroutine. It is used to solve the complex problem by dividing it into sub-part. A function which is called itself again and again or recursively, then this process is called recursion. The iterators can be an option to solve problems, but recursion is […]
The main() function is the top-level function of the Dart. It is the most important and vital function of the Dart programming language. The execution of the programming starts with the main() function. The main() function can be used only once in a program. It is responsible for all types of execution such as user-defined statements, functions, and libraries function. The […]
We have learned the Dart Function, which is defined by using a user-define name. Dart also provides the facility to specify a nameless function or function without a name. This type of function is known as an anonymous function, lambda, or closure. An anonymous function behaves the same as a regular function, but it does not […]
Dart function is a set of codes that together perform a specific task. It is used to break the large code into smaller modules and reuse it when needed. Functions make the program more readable and easy to debug. It improves the modular approach and enhances the code reusability. Suppose, we write a simple calculator […]
Dart Boolean data type is used to check whether a given statement true or false. The true and false are the two values of the Boolean type, which are both compile-time constants. In Dart, The numeric value 1 or 0 cannot be used to specify the true or false. The bool keyword is used to represent the Boolean value. The syntax of declaring the Boolean […]
