Info

Optional as. maybeAs returns the current object if the type is the same and null otherwise
maybeAsOr returns the current object or default value
so it safe to use and avoid constructions like this:

dynamic object = 1; 
object is String ? object : null; 
object is String ? object :  "test"; 

Example

import 'package:maybe_as/maybe_as.dart';

"1".maybeAs<String>() // -> "1"
1.maybeAs<String>() // -> null
"1".maybeAsOr<int>(0) // -> 0
1.maybeAsOr<String>("0") // -> "0"

with dynamic type

dynamic variable;
variable = 1;
(variable as Object).maybeAsOr<String>("0") // -> "0"
variable = "string";
variable.maybeAsOr<String>("0") // -> "string"
