fetchJsonAsOptional<T>({required FetchJsonParser fromJson, required FetchFunction fetch}) → Future<Optional<T>>

fetchJsonAsOptional is a helper for fetching and parsing JSON data.

tryOptionalOrElse<T>(TryOptionalFutureFunction<T> future, {Optional<T> elseValue = const Optional.empty()}) → Future<Optional<T>>

tryOptionalOrElse allows to get an elseValue when a optional future throws an error.

tryOrElse<T>(TryFutureFunction<T> future, {Optional<T> elseValue = const Optional.empty()}) → Future<Optional<T>>

tryOrElse allows to get an elseValue when a future throws an error.
