Bug

Hello. I was struggling configure the pushNotification plugin in my own application so I decided to check if it was working on the example app

Onde I launched it I tried localNotifications, working fine. However I wanted to try a remote notification (what i want to do in my own app as well) and filled in the input to configure my FCM senderID. Seems the app crash at this step when I click the button. I investigated a bit and it seems to come from the onRegister function but I can’t find what cause the problem exactly. I recently updated the package from 3.1.9 to 3.2.1 and since then it doesn’t work anymore. The steps to configure the PushNotifications plugins were working fine in 3.1.9, I could register and receiver notifications as expected

Any idea ?
