**notice:** Dart function parameter `thisVal` is used to store `this` in js.
**notice:** `JSInvokable` does not extend `Function`, but can be used same as `Function`.
Dart function uses named argument `thisVal` to manage js function `this`:
```dart
func(arg1, arg2, {thisVal});
```
or use `invoke` method to pass list parameters:
```dart
(func as JSInvokable).invoke([arg1, arg2], thisVal);
```
