Throwing unhandled Exception

[s-bauer]

I'm facing an issue when I want to create a new notification. The notification will be created, but the method throws an exception. Can you please look into this?

It even happens with the most basic usage: LocalNotifications.createNotification( title: "Hello", content: "There" );

E/flutter ( 8948): [ERROR:topaz/lib/tonic/logging/dart_error.cc(16)] Unhandled exception:
E/flutter ( 8948): type '_Future' is not a subtype of type 'Future<int>' where

This might be due to strong mode in Dart 2. I had developed this plugin on an older version of dart and flutter. I'll see if I can update this to work on Dart 2 without issues.

This should be fixed with e4310de1f2ed50d71c51ae634801803a8ae6623f , I'll push out an update to the package later in the week and let you know when that's available. Leaving this open until then.

@mitchhymel Thank you very much! Sadly, I'm now facing problems when trying to build the flutter application for iOS (see log below). I've never developed for iOS / macOS, so I don't really know how to solve this. Can you please check that too? Thanks

I'm also very new to iOS (only have a weekend's worth of experience), so this may take some time to figure out. It's possible the iOS part of the plugin was not prepared properly, as there are other potentially related issues (#5 ). Will try to look into this over the weekend.

@mitchhymel Thank you very much. I'll probably help you expanding this library in the future, as it's a must have for flutter and there's nothing similar available yet!
