What are the correct Xamarin.Forms.Keyboard mappings for a custom renderer?

Or better yet, is there a method in Xamarin.Forms that'll set it for me?

Here's what I have so far, but I know I'm way off, and don't support KeyboardFlags, which I'd like to be able to.

Droid

private void SetKeyboard()
{
    if (Element.Keyboard == Keyboard.Url)
    {
        NativeView.EditText.InputType = InputTypes.ClassText | InputTypes.TextVariationUri;
    }
    else if (Element.Keyboard == Keyboard.Email)
    {
        NativeView.EditText.InputType = InputTypes.ClassText | InputTypes.TextVariationEmailAddress;
    }
    else if (Element.Keyboard == Keyboard.Numeric)
    {
        NativeView.EditText.InputType = InputTypes.ClassNumber;
    }
    else if (Element.Keyboard == Keyboard.Chat)
    {
        NativeView.EditText.InputType = InputTypes.ClassText | InputTypes.TextVariationShortMessage;
    }
    else if (Element.Keyboard == Keyboard.Telephone)
    {
        NativeView.EditText.InputType = InputTypes.ClassPhone;
    }
    else if (Element.Keyboard == Keyboard.Text)
    {
        NativeView.EditText.InputType = InputTypes.ClassText | InputTypes.TextFlagNoSuggestions;
    }
}

private void SetKeyboard()
{
    if (Element.Keyboard == Keyboard.Chat)
    {
        NativeView.KeyboardType = UIKeyboardType.Twitter;
    }
    else if (Element.Keyboard == Keyboard.Text)
    {
        NativeView.KeyboardType = UIKeyboardType.ASCIICapable;
    }
    else if (Element.Keyboard == Keyboard.Numeric)
    {
        NativeView.KeyboardType = UIKeyboardType.NumberPad;
    }
    else if (Element.Keyboard == Keyboard.Telephone)
    {
        NativeView.KeyboardType = UIKeyboardType.PhonePad;
    }
    else if (Element.Keyboard == Keyboard.Url)
    {
        NativeView.KeyboardType = UIKeyboardType.Url;
    }
    else if (Element.Keyboard == Keyboard.Email)
    {
        NativeView.KeyboardType = UIKeyboardType.EmailAddress;
    }
}
