Molecule<T> class

A Molecule is a derived state from one or multiple Atoms. This is a generic class which allows it to be used very dynamically.

Example usage:

var myMolecule = Molecule<int>(
  atomKeys: ['someAtom'],
  computer: (atoms) => atoms.values.fold<int>(
    0, (previousValue, element) => previousValue + element.state),
  key: 'myMolecule'));
myMolecule.stateStream.listen((state) => print(state));

Constructors

Molecule({required List<Atom> atoms, required T computer(Atom<E>? <E>(String getAtom)), required String key})
Constructor. atoms the Atoms to be used when computing this Molecule's value. computer the function that computes this Molecule's value. key this Molecule's globally unique key.

Properties

hashCode → int
The hash code for this object.
no setterinherited
key ↔ String
A globally unique key. Usually the same as the name of this Molecule.
latefinal
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
state → T
Get the state of this Molecule.
no setter
stateStream → Stream<T>
A broadcast stream that can be listened to. Whenever the state of this Molecule changes a new event will be emited on this stream providing the listener with the new state.
no setter

Methods

dispose() → void
The dispose method should always be called before this Molecule is destroyed. It will close _controller. Think of this as a destructor that you have to manually call.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
