dart - No top-level method 'spawnFunction' declared

Question

I'm trying to use Isolates in Dart. The tutorials from dartlang.org seem to use the function spawnFunction. But that does not seem to work for me. And I cant find any docs about this.

import 'dart:isolate';

void doThing() {
  print('Hello!');
}

main() {
  spawnFunction(doThing);
}

.

Unhandled exception:
No top-level method 'spawnFunction' declared.

The docs from api.dartlang.org mention Isolate.spawn but I get an error saying there is no static method spawn declared.

Did I miss something? A link to appropriate docs (if any) would be appreciated.

Thanks!

Isolate.spawn 确实是创建隔离的新方法。您的示例需要重写为：

import 'dart:isolate';

void doThing(_) {
  print("Hello!");
}

main() {
  Isolate.spawn(doThing, null);
}
