Description:

nmap

Dart Null Map #
A dart package that provides != null map operation extension (null map, nmap).
The null map operator applies the passed convert function on receiver if it is not null, returns null otherwise.
Note: this package is a temporary solution to the open Dart lang issue https://github.com/dart-lang/language/issues/361 while waiting for an actual language operator implementation.
Usage #
final int? a = null;
final int b = 1;

print(a.nmap((n) => n + 1)); // null
print(b.nmap((n) => n + 1)); // 2
