Is it possible to concatenate integers without converting to String first?
int _test1 = 123;
int _test2 = 456;
print(int.parse(("$_test1"+"$_test2"))); // 123456

what result do you want to achieve? – pskink Jan 19 '20 at 16:40

@pskink To join _test1 and _test2 into one number (123456), but keeping it an integer. Wasn't sure if there is a better way to the one I illustrated – Mr Jax Jan 19 '20 at 16:43

`_test1 * 1000 + _test2` – pskink Jan 19 '20 at 16:44

@pskink That assumes the integers are the same length though – Mr Jax Jan 19 '20 at 16:47

no, you can have `_test1` as any number – pskink Jan 19 '20 at 16:48

@pskink But not _test2 – Mr Jax Jan 19 '20 at 16:49

My bad I didn't read without converting to String first. – Federick Jonathan Jan 19 '20 at 17:58

you can do it like this
void main() {
int _test1 = 123;
int _test2 = 456;
int pow = 10;
while(_test2 >= pow)
pow *= 10;
print(_test1 *pow + _test2);
}
