setBadgeNumber() blocking UI on iOS

[jeremycastelli]

Hey !
First I want to thank you for the revival of this plugin. You have done a brilliant work ! Thank you !
I don't know if it's the responsability of the plugin or the firebase SDK, calling the methods get/setBadgeNumber() block the UI which become totally non responsive for about 5-10sec.
and here is what I have at the same time in Xcode's console
