Assignment Operators

on Saturday, 18th of July, 2020

Assigning a value to a variable in Dart is done by using the = operator.

var name = "PJ"; 

Dart also supports compound operators, which are the equivalent of performing an operation and assignment.

-=subtraction assignment
/=divisions assigment
%=modulo assignment
+=addition assignment
~/=integer division assignment
>>=bitwise shift right assignment
^=bitwise XOR assignment
<<=bitwise shift left assignment
&=bitwise and assignment
|=bitwise or assignment


a -= b;
// above is shorthand for
a = a - b;

// *= example
var a = 2; // Assign using =
a *= 3; // Assign and multiply: a = a * 3
assert(a == 6);
