Right<L, R> class

A concrete implementation of Either that represents the successful value (Right) in a computation.

Commonly used in functional programming to wrap a successful result, while the Left represents a failure or error.

Example usage:

Either<String, int> result = Right(42);
print(result.isRight()); // true

Methods

flatMap<R2>(Either<L, R2> f(R right)) → Either<L, R2>

Applies the given function f to the contained value, and flattens the result.

override

fold<B>(B ifLeft(L left), B ifRight(R right)) → B

Applies ifRight to the contained value and returns its result.

override

getLeft() → L

Throws an Exception because this is a Right and does not contain a Left value.

override

getRight() → R

Returns the contained value.

override

isLeft() → bool

Always returns false because this is a Right.

override

isRight() → bool

Always returns true because this is a Right.

override

map<R2>(R2 f(R right)) → Either<L, R2>

Transforms the contained value using the provided function f, returning a new Right.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
