Write a function `int plainSum(int, int, int)` which takes 3 integers and returns their sum.

Functions in Dart are declared as follows:
|
||
|
|
|
||
|
|
```dart
|
||
|
|
bool isEven(int num) {
|
||
|
|
return num % 2;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```dart
|
||
|
|
void main() {
|
||
|
|
var res = plainSum(1, 2, 3);
|
||
|
|
print(res); // prints 6
|
||
|
|
}
|
||
|
|
```
