Isolates

Most computers, even on mobile platforms, have multi-core CPUs.To take advantage of all those cores, developers traditionally useshared-memory threads running concurrently. However, shared-stateconcurrency is error prone and can lead to complicated code.

Instead of threads, all Dart code runs inside of isolates. Eachisolate has its own memory heap, ensuring that no isolate’s state isaccessible from any other isolate.
