Dart Methods

A set of statements with some properties to class objects is called a Dart method. It gives us the ability to carry out certain operations, and we can call it by name within the program when we need it. Methods carry out the particular function of that program by breaking the major task up into smaller ones. This procedure improves the program’s modular architecture and increases code reuse. In order to do a particular task, the methods can be defined using arguments that are supplied as information. Afterwards, they can either return nothing or return value to the caller. methods that are defined as either class methods or instance methods in the class.

Instance Methods

Instance methods are those that can be accessed by utilizing the class instance. It is possible for the instance methods to have arguments or not. This keyword can be accessed via the instance method via the instance variable.

Creating Instance Methods

A proper return type and name define an instance method. It might have a parameter list. Below is the syntax.

Syntax

				
					return_type method_name(<list of arguments>)   
{  
//statement(s)  
}  
				
			

Calling instance Method

The class object is used to access instance methods, therefore in order to use them, we must first build an object. Below is the syntax.

Syntax

				
					ClassName objName = new ClassName()  
objName.methodName()  
				
			

Class Methods

The static keyword is used to declare the class method. Rather than utilizing the class object, the class name can be used to retrieve it. These are universal methods shared by all instances of that specific class. Only the static variables are accessible via the static methods.

Creating Class Methods

The static keyword, the method name, and the return type are used to declare a static method. Below is the syntax.

Syntax

				
					static return_type method_name(){  
  //statement(s)  
}  
				
			

Calling Class Method

By using the class name rather than the class object, the class method can be invoked directly. Below is the syntax.

Syntax

				
					ClassName.classMethod()
