Static Properties
Properties
final int hashCode #
Get a hash code for this object.
All objects have hash codes. Hash codes are guaranteed to be the
same for objects that are equal when compared using the equality
operator ==. Other than that there are no guarantees about
the hash codes. They will not be consistent between runs and
there are no distribution guarantees.
If a subclass overrides hashCode it should override the
equality operator as well to maintain consistency.
int get hashCode => Primitives.objectHashCode(this);
Operators
bool operator ==(other) #
The equality operator.
The default behavior for all Objects is to return true if and
only if this and
other are the same object.
If a subclass overrides the equality operator it should override
the hashCode method as well to maintain consistency.
bool operator ==(other) => identical(this, other);

dynamic noSuchMethod(Invocation invocation) #
noSuchMethod is invoked when users invoke a non-existant method
on an object. The name of the method and the arguments of the
invocation are passed to noSuchMethod in an Invocation.
If noSuchMethod returns a value, that value becomes the result of
the original invocation.
The default behavior of noSuchMethod is to throw a
noSuchMethodError.
