Properties

asJust → Just<T>
Cast this into a Just, and throw an exception if the cast fails! It might be tempting to just cast the Maybe into the desired type, but it's strongly advised to not do that indiscriminately. Although, it might be convenient to have this cast sometimes. Use it wisely!
no setterinherited
asNothing → Nothing
Cast this into a Nothing, and throw an exception if the cast fails! It might be tempting to just cast the Maybe into the desired type, but it's strongly advised to not do that indiscriminately. Although, it might be convenient to have this cast sometimes. Use it wisely!

Methods

getOrElse<Type>(Type fallback) → Type
The getOrElse method which receives a parameter to return as a fallback value, when the value is a Nothing, or there is no value in the Just.
inherited
map<TResult extends Object?>({required TResult nothing(Nothing<T> value), required TResult just(Just<T> value)}) → TResult
inherited
mapAsyncJust<K>(FutureOr<Maybe<K>> combiner(T)) → FutureOr<Maybe<K>>
A Method to chain async access to data held by the Maybe. If this is Nothing returns Nothing, if this is Just, returns the result of the combiner method over the value inside Just
inherited
mapJust<K>(Maybe<K> combiner(T)) → Maybe<K>
A method to chain access to data held by the Maybe. If this is Nothing returns Nothing, if this is Just, returns the result of the combiner method over the value inside Just

mapOrNull<TResult extends Object?>({TResult? nothing(Nothing<T> value)?, TResult? just(Just<T> value)?}) → TResult?
inherited
maybeMap<TResult extends Object?>({TResult nothing(Nothing<T> value)?, TResult just(Just<T> value)?, required TResult orElse()}) → TResult
inherited
maybeWhen<TResult extends Object?>({TResult nothing()?, TResult just(T value)?, required TResult orElse()}) → TResult
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
