Returns true if other is equals to this.value.
get() → T
Returns the current filed value.
increment(Object? value) → num?
Increments: this.value + value
multiply(dynamic value) → num?
Multiply: this.value * value
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
set<V>(V? value) → void
Sets the field value.
toString() → String
value as String.
