Dart Libraries

In Dart, the library is the collection of the routine or set of programming instructions. Dart consists of many sets of built-in libraries that are beneficial to hold routines (functions, set of classes, etc.), and regularly used. A Dart library contains constants, functions, properties, exceptions, and typedefs, and set of classes.

Constants in Dart

Dart Constant is defined as an immutable object, which means it can't be changed or modified during the execution of the program. Once we initialize the value to the constant variable, it cannot be reassigned later.

Dart Classes and Objects

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 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 its all objects

Dart Methods

A Dart method is the collection of statements that consists of some characteristics to class object. It provides the facility to perform some operation and it can be invoked by using its name when we need in the program.
