Dart 捕获一个区域中的所有期货

在DART中，有没有办法把S在Zone米内创造的Future英尺都捕捉到？

目前，我被迫手动将它们全部捕获，但这似乎很容易忘记这样做.因此，如果可能的话，我想将其自动化.

在下面的示例代码中，我希望捕获someAsyncWork，这样就可以在Main runPluginCode运行后等待它.

import 'dart:async';

Future<void> main() async {
  print('Run plugin code');
  await runZoned(
    () async {
      runPluginCode();

      final tasks = Zone.current['tasks'] as List<Future>;

      await Future.wait(tasks);
    },
    zoneValues: {
      'taskId': 123,
      'tasks': <Future>[],
    },
  );
  print('Exit plugin code');
}

void runPluginCode() {
  // External QuickJS script that only has sync API methods
  // but they may call into async functions that need to be awaited before
  // the plugin code ends
  someTask();
}

void someTask() {
  print('performing task');
  // I don't want manually do this everywhere
  // final tasks = Zone.current['tasks'] as List<Future>;
  // tasks.add(someAsyncWork());
  someAsyncWork();
}

Future<void> someAsyncWork() async {
  await Future.delayed(const Duration(milliseconds: 200));
  final taskId = Zone.current['taskId'] as int;
  print('async work completed for task $taskId did I complete inside the plugin code???');
}

我相信这应该是可能的，当使用自定义ZoneSpecification

我试过了，但一点运气都没有.

    zoneSpecification: ZoneSpecification(
      run: <R>(self, parent, zone, f) {
        final task = parent.run(zone, f);
        if (task is Future) {
          (zone['tasks'] as List<Future>).add(task);
        }
        return task;
      },
      runUnary: <R, T>(self, parent, zone, f, arg) {
        final task = parent.runUnary(zone, f, arg);
        if (task is Future) {
          (zone['tasks'] as List<Future>).add(task);
        }
        return task;
      },
      runBinary: <R, T1, T2>(self, parent, zone, f, arg1, arg2) {
        final task = parent.runBinary(zone, f, arg1, arg2);
        if (task is Future) {
          (zone['tasks'] as List<Future>).add(task);
        }
        return task;
      },
    )
