Angular 7 Support

[daveparks23]

npm WARN angular2-flash-messages@3.0.1 requires a peer of @angular/core@^6.0.0 but none is installed. You must install peer dependencies yourself.

Would love to use this on Angular 7.x Thanks for all you do. Let me know if I could help in some way.

In my experience it works fine, even though the warnings appear... I'd like them to disappear though...

Just checking to see if there are any plans for an update? So far nothing seems to have changed as mentioned above but I would also like to see the warnings disappear.

Since it's just a peer dependency warning, and the module is working fine with Angular 7, I made the warnings disappear by changing the peer dependency on angular core in angular2-flash-messages' package.json to ^7.0.0.
