'get' & 'set' as getters and setters

get and set are just syntactic sugar and are just type of methods. So, everything they do can also be done by simple user-define methods/functions.

get - getters

int get val => returnValue; .. MUST have return type

Purpose: to get or access a value may be to print or assign to other variables or use anywhere else.

Example of default getter is: print(obj.x);

get is a short form of writing a function of return type

get is called just like a variable as obj.get_VariableName

get getter	int function()
don't need parameters as its called like a variable	can take parameters
=> is used	=> is used as its a function with a return type
called by obj.get_VariableName	called by obj.functionName() parenthesis() is used as functionName is a function

info

  int get area => width * height;

/* called as: */
  // print(obj.area);

'get' without '=>'

  int get area {
    return width * height;
  }

'get'⏫ is shortform of:

  int area() {
    return width * height;
  }

/* called as: */
  // print(obj.area());

So, get also known as getters are syntactic-sugar for user-defined methods which created using =>.

set - setters

set increment(CounterModel obj) => ++obj.x; .. MUST NOT have any type

• get means method of return type
• set means method of void type with a single parameter

import 'package:equatable/equatable.dart';

class CounterModel extends Equatable {
  final int x = 0;

  void set increment(x) => ++x;
  void set decrement(x) => --x;

  @override
  List<Object?> get props => [x];
}
