In this tutorial you will learn about the Dart Assignment operators and its application with practical example.
Dart Assignment Operators
Assignment operators are used to assign value to a variable, you can assign a variable value or the result of an arithmetical expression. In many cases assignment operator can be combined with other operators to build a shorthand version of a assignment statement are known as Compound Statement. For example, instead of a = a+5 , we can write a += 5.
| Operator | Description | Expression |
|---|---|---|
= |
Assignment Operator |
a=b |
+= |
add and assign |
a+=b is equivalent to a=a+b |
-= |
subtract and assign |
a-=b is equivalent to a=a-b |
*= |
multiply and assign |
a*=b is equivalent to a=a*b |
/= |
divide and assign |
a/=b is equivalent to a=a/b |
~/= |
divide and assign(Integer) |
a~/=b is equivalent to a=a~/b |
%= |
mod and assign |
a%=b is equivalent to a=a%b |
<<= |
Left shift AND assign |
a<<=5 is equivalent to a=a<<5 |
>>= |
Right shift AND assign |
a>>=5 is equivalent to a=a>>5 |
&= |
Bitwise AND assign |
a&=5 is equivalent to a=a&5 |
^= |
Bitwise exclusive OR and assign |
a^=5 is equivalent to a=a^5 |
|= |
Bitwise inclusive OR and assign |
a|=5 is equivalent to a=a|5 |
Example:-
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
void main() { var a = 30; var b = 5; print("W3Adda - Dart Assignment Operators"); a+=b; print("a+=b : ${a}"); a-=b; print("a-=b : ${a}"); a*=b; print("a*=b : ${a}"); a~/=b; print("a~/=b : ${a}"); a%=b; print("a%=b : ${a}"); } |
When you run the above Dart program, you will see following output.
