Architecture

I get a lot of questions about architecture and how to unit tests plugins. So here are some things to be aware of for any plugin that I publish.

What’s with this .Current Global Variable? Why can’t I use $FAVORITE_IOC_LIBRARY

You totally can! Every plugin I create is based on an interface. The static singleton just gives you a super simple way of gaining access to the platform implementation. Realize that the implementation of the plugin lives in your iOS, Android, Windows, etc. This means you will need to register it there by instantiating a Cross___Implementation from the platform specific projects.

If you are using a ViewModel/IOC approach your code may look like:

public MyViewModel()
{
    readonly IPLUGIN plugin;
    public MyViewModel(IPLUGIN plugin)
    {
        this.plugin = plugin;
    }
}
