Isolates
As the name implies, Dart isolates are used to isolate long-running functions from the main thread of execution. Dart isolates do not share any memory so they rely on message passing for communication, making for very elegant concurrent programming solutions. Message passing is achieved through port objects and uses Futures to signal when isolates and messages are ready.
Isolates are imported from the dart:isolate library. The easiest way to use them is with the Isolate.spawnUri() method.
| isolates/test/isolates.dart | |
| | import 'dart:isolate'; |
| | var res = new ReceivePort(); |
| | var sender = Isolate.spawnUri( |
| | Uri.parse('isolates/main.dart'), |
| | ['2014'], |
| | res.sendPort |
| | ); |
| | sender. |
| | then((_)=> res.first). |
| | then((message) { |
