How to find the hash value of a string in Dart:
We can find the hash code of a dart string easily. It is an integer value, that is calculated from the code units of the string. It will be always different, only for a same string with same sequence of characters will give the same value. We can calculate the hash value of multiple strings and compare them using == operator.
Syntax of hashCode:
The syntax of hashCode is as below:
int get hashCode;It is defined in the String class of dart.
Example of hashCode:
Let’s write a program to find the hashCode of different strings:
void main() {
var str_one = "hello";
var str_two = "world";
var str_three = "hello";
print(str_one.hashCode);
print(str_two.hashCode);
print(str_three.hashCode);
}It will print the below output:
150804507
278506468
150804507
As you can see here, the first and the third print prints the same value because both are same strings.
