将dart方法注入到js引擎后, 通过js对象调用该方法总是返回Future<dynamic>

[jiajiawei]

您好, 非常感谢作者提供的这个仓库...

我测试代码如下 , 也可以尝试我创建的测试例子 https://github.com/jiajiawei/test_flutter_qjs

var a = 1;
final engine = FlutterQjs()..dispatch();
try {
  JSInvokable setToObject =
      engine.evaluate('(key, value) => this[key] = value;');
  setToObject.invoke(['a', IsolateFunction(() => a)]);
  print(engine.evaluate('a()'));    // Instance of 'Future<dynamic>'
} catch (e) {
  print('[JsEngine] Fail to eval script. \n$e');
} finally {
  engine.port.close();
}

我想得到1,但是结果是Instance of 'Future'

我改了object.dart三处代码, 把Future 和 aysnc都去掉临时解决了. 但是我觉得这不是正常方案. 希望作者有空解决下. 感激不尽

(还有272行的invoke方法没截上)

直接传function

var a = 1;
final engine = FlutterQjs()..dispatch();
try {
  JSInvokable setToObject =
      engine.evaluate('(key, value) => this[key] = value;');
  setToObject.invoke(['a', () => a]);
  print(engine.evaluate('a()'));
} catch (e) {
  print('[JsEngine] Fail to eval script. \n$e');
} finally {
  engine.port.close();
}

IsolateFunction 是为了多线程（isolate）模式能异步调用做的wrapper
