[V3] ref.onDisconnect().setValue() allows only strings or objects

[florianbepunkt]

ref.onDiscconnect().setValue() only allows for strings and objects…

this makes it difficult to implement a presence system (storing timestamp or a isOnline boolean).

I checked the iOS and android code and there are only methods for setting string and objects. I tried adding additional native methods to handle ints and bools but failed miserably

in iOS adding the following method

RCT_EXPORT_METHOD(onDisconnectSetNumber:(NSString *) path
                  val:(NSNumber *) val
                  callback:(RCTResponseSenderBlock) callback)
{
    FIRDatabaseReference *ref = [self getPathRef:path];
    [ref onDisconnectSetValue:val
          withCompletionBlock:^(NSError * _Nullable error, FIRDatabaseReference * _Nonnull ref) {
              [self handleCallback:@"onDisconnectSetNumber" callback:callback databaseError:error];
          }];
}

gives me a conversion error…

Implicit conversion of a non-Objective-C pointer type 'long *' to 'id _Nullable' is disallowed with ARC

any idea on how to fix this? I could add the methods for ints and bools in the native code and change the js part to check the type of value and call the right method accordingly.
