Sqrt in Dart

In Dart, we can use the sqrt() function from the dart:math library to get the square root of a number.

Here is an example:

import 'dart:math';
void main() {

  double number = 25;

  double result = sqrt(number);

  print('The square root of $number is $result');

}

The above code will output:

The square root of 25.0 is 5.0

Note that the sqrt() function returns a double value. If the input number is negative, the function will return NaN (Not a Number).
