Usage

Instead of using an Entry simply use a ValidatorEntry instead!

You MUST set the Length value if your control is a LenghtValidator.

You can also:

Change color of error message and customize their content.
Change placeholder.
Choose if success icon is displayed.
Choose if error message is displayed.

Here is a sample:

new LengthValidator
{
  PlaceHolder = "Enter number of credit card",
  Lenght = 16,
  ErrorMessageColor = Color.Black,
  ShowIcon = true,
  ShowMessageError = true
}

XAML:

First add the xmlns namespace:

xmlns:validator="clr-namespace:EntryValidator.FormsPlugin.Abstractions;assembly=EntryValidator.FormsPlugin.Abstractions"

Then add the xaml:

<validator:LengthValidator 
       x:Name="length" 
       ErrorMessageColor="Black" 
       ShowIcon="True" 
       ShowMessageError="True"  
       PlaceHolder="Enter number of credit card" 
       VerticalOptions="CenterAndExpand" 
       Length="16"/>
