Agent<T> class

State that lives on an isolate.

This is a convenient wrapper around having an isolate, dart ports and managing some state that is edited on the isolate.

Properties

error → Future<AgentError?>

Gets the current error associated with the Agent, null if there is none.

no setter

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

exit() → Future<T>

Kills the agent and returns its state value. This is faster than calling deref then kill since Dart will elide the copy of the result.

kill() → void

Kills the Agent's isolate. Any interaction with the Agent after this will result in a StateError.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

read<U>({U query(T state)?}) → Future<U>

Reads the Agent's state with a closure.

resetError() → Future<void>

Resets the Agent so it can start receiving messages again.

toString() → String

A string representation of this object.

inherited

update(T func(T)) → Future<void>

Send a closure func that will be executed in the Agent's Isolate. The result of func is assigned to the value of the Agent.

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

create<T>(T func()) → Future<Agent<T>>

Creates the Agent whose initial state is the result of executing func.
