create static method
Asynchronously create size
runners and create a LoadBalancer
of those.
This is a helper function that makes it easy to create a LoadBalancer
with asynchronously created runners, for example:
var isolatePool = LoadBalancer.create(10, IsolateRunner.spawn);
Implementation
static Future<LoadBalancer> create(
int size, Future<Runner> Function() createRunner) {
return Future.wait(Iterable.generate(size, (_) => createRunner()),
cleanUp: (Runner runner) {
runner.close();
}).then((runners) => LoadBalancer(runners));
}
