Visibility modifiers in Kotlin are keywords that set the visibility of classes, objects, interfaces, constructors, functions, and properties.
There are Four types of visibility modifiers in Kotlin.
The purpose of modifiers is to provide accessibility to classes, objects, functions, etc.Basically, there is no need to set modifiers for getters as they have the same visibility as their properties. The public is the default modifier. Also,If you don’t define any modifier it will serve as a Default modifier.
It is the default visibility modifier in Kotlin.Classes, variables, and interfaces are visible everywhere which are public.It is also a frequently used modifier.Generally used when no need to implement restrictions on field function and variables.
Private modifiers are only allowed within the block in which property is declared.It does not allow outside access.A private package can only be accessible within that specific file.Generally used when implementing more restrictions on field function and variables.For Example
Protected modifier with class and interface only visible to its class or subclass An overridden, protected declaration in its subclass will also be a protected modifier until we change explicitly.Generally used when implementing more restrictions on field function and variables.
The internal modifier makes the field visible only inside the module.Error Will through if we access any field outside the module.Generally used with Api-related Work.
