SharedData<D, S> class
Class for shared data between AsyncTask instances.
This instance will be transferred to the executor thread/isolate only once, and not per task, avoiding the Isolate messaging bottle neck.
- The internal data should NOT be modified after instantiated.
S
should be a simple type that can be sent through threads/isolates or serialized as JSON.- The default implementation supports Dart basic types: primitive values (null, num, bool, double, String), lists and maps whose elements are any of these.

Properties
- allowCopyBySerialization ↔ bool
-
getter/setter pair
- data → D
-
The actual data.

D, S> Function(S serial)?) -
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- noSerializationOnDartNative ↔ bool
-
If true no serialization will be performed when transferring
this data to another Isolate. A platform dependent object memory
copy will be performed.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.

- signature → String
-
The signature of data, computed only once.

cast<
X, Y> () → SharedData< X, Y> - Casts to SharedData<X, Y>.
-
computeSignature(
) → String - The computation of signature.
-
copy(
) → SharedData< D, S> - Creates a copy of this instance.
-
deserialize(
S serial, {AsyncTaskPlatform? platform}) → SharedData< D, S> -
Deserialize a SharedData from
serial
. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reset(
) → void - Dispose any cached computation, like signature and serializeCached.
-
serialize(
{AsyncTaskPlatform? platform}) → S -
Serializes this instance to
S
. -
serializeCached(
{AsyncTaskPlatform? platform}) → S -

S
using a cache for recurrent calls. -
toString(
) → String -
