GgValue class - gg_value library

Constructors

GgValue({required T seed, bool spam = false, bool compare(T a, T b)?, T transform(T)?, bool isOk(T)?, T parse(String)?, String stringify(T)?, String? name}): seed The initial seed of the value.

If spam is true, each change of the value will be added to the stream.

If spam is false, updates of the value are scheduled as micro tasks. New updates are not added until the last update has been delivered. Only the last set value will be delivered.

transform allows you to keep value in a given range or transform it.

parse is needed when T is not String, int, double or bool. It converts a string into T.

stringify is needed when T is not String, int, double or bool. It converts the value into a String.

name is an optional identifier for the value.

changeStream → Stream<GgChange<T>>: no setter
compare → (bool Function(T a, T b)?): Set a custom comparison operator
final
hashCode → int: The hashcode of a GgValue is calculated based on the value.
no setteroverride
isOk → (bool Function(T)?): Use that callback to perform some validation
final
isSynced → bool: no setter
jsonDecodedValue ↔ dynamic: Returns int, double and bool and string as they are.
getter/setter pairoverride-getter
name → String?: An optional name.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
seed → T: The default value
no setteroverride
spam ↔ bool: Allows reducing the number of updates delivered when the value is changed multiple times.
getter/setter pairoverride-getter
stream → _GgValueStream<T>: Returns a stream informing about changes on the value
no setteroverride
stringValue ↔ String: Converts the value into a string value and returns the result.
getter/setter pairoverride-getter
syncStream → _GgValueStream<T>: Returns a sync stream informing about changes on the value
no setteroverride
transform → (T Function(T)?): Is used to transform assigned values to other ones, e.g. to keep the value in a given range.
final
value ↔ T: Returns the value
getter/setter pairoverride-getter

dispose() → void: Call this method when the value is about to be released.
forceUpdate() → void: Informs all listeners about a change.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
reset() → void
syncWith(GgValue<T> other) → void: Two way sync this value with another value
toString() → String: Returns a string representation of the GgValue.
override
unsync() → void: Remove the synchronization with another element

operator ==(Object other) → bool: This operator compares to GgValue objects based on the value. When given, the compare function is used to make the comparison.
