Constructors

hashCode → int: The hash code for this object.
no setterinherited
maxAge → Duration?: The maximum duration a value will be cached. Null means no expiration.
final
provider → (Future<T> Function()?): If provided, the cache will get the value by using this provider function when value is called and the value is not cached. If this is not set, value cannot be called, and getOrFetch must be used
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
value → Future<T>: Uses provider to get the value if it is not cached, or returns the cached value if it was. If provider is not set, this will throw an exception
no setter

clear() → void: Clear the cached value. Calling value or getOrFetch will cause the provider to be run again. Calls which are already in progress and not finished will NOT be cancelled and still receive the value when they complete
getOrFetch(Future<T> provider()) → Future<T>: Gets or computes the value using the provided provider function.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
