Drop-Down not working at all on Android

[adolfos94]

Hello,

I implemented the DropDown on my hybrid app. On iOS it works perfectly, but on Android it crashes.

@adolfos94 , can you provide a reproducable demo or reproduce it with the demos in this repo?

[adolfos94]

Ok, I found that If I don't use the property color in the dropdown it crashes. Should be a default value. Regards.

I also have the same issue with dropdown on android. I used the same code that is available in the nativescript marketplace page.

Here is a link for the stackoverflow question https://stackoverflow.com/questions/46541759/nativescript-dropdown-plugin-angular-error-on-opening-the-item?noredirect=1#comment80047944_46541759

Adding black color works, I've tried grey or blue and it crashes! weird!
