Can you provide an example of using the Email plugin in a Xamarin.Forms project with MvvmCross

Step 1: Install MvvmCross and Email Plugin

First, ensure that your Xamarin.Forms project is set up with MvvmCross. You will need to install the MvvmCross packages in your Core, iOS, and Android projects. Additionally, install the MvvmCross Email plugin in your Core project.

You can install these packages via NuGet:

- MvvmCross Core**
- MvvmCross Forms**
- MvvmCross Email Plugin**

Step 2: Register the Email Plugin

In your Core project, you need to register the Email plugin in the `Initialize` method of your `App` class. However, MvvmCross plugins are typically registered automatically when you install them via NuGet. If you encounter issues, ensure that all MvvmCross versions are consistent across your projects.

Step 3: Use the Email Plugin in Your ViewModel

To use the Email plugin, you need to inject the `IMvxComposeEmailTask` interface into your ViewModel. Here’s how you can do it:

csharp
using MvvmCross.Plugins.Email;

public class MyViewModel : MvxViewModel
{
    private readonly IMvxComposeEmailTask _emailTask;

    public MyViewModel(IMvxComposeEmailTask emailTask)
    {
        _emailTask = emailTask;
    }

    public void SendEmail()
    {
        _emailTask.ComposeEmail(
            "
 <script language='JavaScript' type='text/javascript'>
 <!--
 var prefix = 'm&#97;&#105;lt&#111;:';
 var suffix = '';
 var attribs = '';
 var path = 'hr' + 'ef' + '=';
 var addy91614 = 'r&#101;c&#105;p&#105;&#101;nt' + '&#64;';
 addy91614 = addy91614 + '&#101;x&#97;mpl&#101;' + '&#46;' + 'c&#111;m';
 document.write( '<a ' + path + '\'' + prefix + addy91614 + suffix + '\'' + attribs + '>' );
 document.write( addy91614 );
 document.write( '<\/a>' );
 //-->
 </script><script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '<span style=\'display: none;\'>' );
 //-->
 </script>This e-mail address is being protected from spambots. You need JavaScript enabled to view it
 <script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '</' );
 document.write( 'span>' );
 //-->
 </script>",
            string.Empty,
            "Subject",
            "Body of the email",
            false);
    }
}

Step 4: Call the SendEmail Method

You can call the `SendEmail` method from your View. For example, you might have a button in your XAML that triggers this method:

xml

And in your ViewModel, you would define the command:

csharp
public ICommand SendEmailCommand { get; private set; }

public MyViewModel(IMvxComposeEmailTask emailTask)
{
    _emailTask = emailTask;
    SendEmailCommand = new MvxCommand(SendEmail);
}

Step 5: Ensure Platform-Specific Setup

For Xamarin.Forms, MvvmCross handles the platform-specific setup automatically when you use the `MvxFormsApplicationDelegate` and platform-specific setup classes like `MvxFormsAndroidSetup` and `MvxFormsIosSetup`. Ensure these are correctly implemented in your project.

Step 6: Testing

Finally, test your application on different platforms to ensure the Email plugin works as expected. The plugin should open the default email client on each platform with the specified details.

By following these steps, you can effectively integrate the Email plugin into your Xamarin.Forms project using MvvmCross.
