Typedefs

ASyncDefer<T> = FutureOr<T?> Function(GetterMethod<T> result, GenericGetterMethod recover)

Signature of AsyncDeffer that has two parameters a getter that returns result (result()) and recover parameter that returns exception of the given type (recover<type>())

ASyncDefferable<T> = FutureOr<T?> Function(void defer(ASyncDefer<T> ))

Signature of ASyncDefferable task that has a parameter: defer that can be used to schedule a task to be executed after scope exits

GenericGetterMethod = E? Function<E extends Object?>()

used as recovery method to indicate what kind of error to recover from

GetterMethod<E extends Object?> = E? Function()

Simple getter method that returns E
