Get error messages of rules from String or Resources instead of hardcoded ones

Every Rule class such as EmailRule has a method called as getErrorMessage() which returns the error message when validation is failed.

For now, all the rules have this message hard coded strings. These error messages should be dynamic and can be fetched from String or Resource.

For example, if we want to change EmailRule, then we can do something like this:

class EmailRule : BaseRule(error: String = "Invalid Email Address!")  // Adding custom error message var
{
    override fun validate(text: String): Boolean {
        return Validator(text).regex(
                "^(([\\w-]+\\.)+[\\w-]+|([a-zA-Z]|[\\w-]{2,}))@"
                        + "((([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\.([0-1]?"
                        + "[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\."
                        + "([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\.([0-1]?"
                        + "[0-9]{1,2}|25[0-5]|2[0-4][0-9]))|"
                        + "([a-zA-Z]+[\\w-]+\\.)+[a-zA-Z]{2,4})$"
        ).check()
    }

   // Add a setter for error message
   fun setError(msg: String) { error = msg }    

   override fun getErrorMessage(): String {
       return error               // Return the error message here
   }
}

Hello @emrekose26 , Yeah! It looks like @antercepter isn’t active much on Github. Yes, you can work on this and send me the pull request 😄 I would love to merge it 👍

Well I think this is a complicated situation. For now, if user wants to support multi language, then I think he can do so by fetching resource string himself and passing in the rule as string. For now, let’s skip this resources issue. I will create another issue for this and see what kind of proposals we get. Thank you for your suggestions 😃
