In this blog we will discuss on how to get negitive only random number between specific range in flutter.
Below is the syntax for getting random number in dart file.
```
Random().nextInt(negitiveNumber)-negitiveNumber
```
In the above syntax in place of negitiveNumber we add a number greater than 0.
If suppose if we want to print negitive number upto -50 in Random().nextInt(50) we add 50 as parameter so that random number is generated uptill 50 now we subtract the random number by 50 to get the result.
Below is the example statement.
```
Random().nextInt(50) - 50
```
In the above statement as we subtract 50 from the total sum random number is printed between the range of 0 to -50.

Blow is an example program to print Random number between 0 to -50.

import 'dart:math';
void main() {
print(Random().nextInt(0 + 50) - 50);
}

Output:

-10
