Unable to pass NULL value from JS side to native for primitive types

🐛 Bug Report

I need to pass a primitive type from JS to native side (ObjectiveC/Java). One of requirements: parameter value can be null. But I am not able to do that. I will show all that with boolean, but same problem exists for integer/double types as well.

To Reproduce

1. Make a method on native side with nullable boolean input parameter;
2. Make a call from JS side and pass null;
3. You’ll get a crash;

Expected Behavior

null value is passed to native side (ObjectiveC/Java)

Code Example

JS side:

myFoo() {
  return some_module.myFoo(null);
}

Java side:

@ReactMethod
public void doFoo(@Nullable final Boolean myValue) {
  Log.d("my_app", "myValue: " + myValue);
}

ObjectiveC side:

RCT_REMAP_METHOD(doFoo, withMyValue:(nullable NSNumber*)myValue) {
  NSLog(@"myValue: %@", myValue);
}

I was unable to find any information, why it is implemented in such way neither in issues list here in github repo, neither in stackoverflow or similar.

Can anyone give some notes about this?
