-> How to understand that the exception was thrown due to the absence of a file?
->    
-> For some OSs a missing file and a missing parent directory are two 
-> different problems. Other OSs see them as the same problem. Dart 
-> throws the same type of exception not only for these two errors, 
-> but also for any file errors. The exception has `int` error code, but the 
-> error codes are different on different OSs.

-This library is designed to generalize error codes, reducing them to a "common 
-denominator". It interprets the `OSError.errorCode` value depending on the 
-current platform.

-Functions unit-tested on **Linux**, **Windows** and **MacOS**. Mobile systems 
-such as **Android** and **iOS** have the same kernels as their desktop 
-relatives. So the error messages are almost certainly the same.
