Constrains data to positive integers.
It sets the inputFormatters
to deny non-digt characters except the plus
'+' sign.
trim
whether or not to trim the input value.
validator
an optional extra validation step.
blank
the error message in case of blank field; if omitted, the field
will not be made required.
malformed
the error message for non-integer input values.
neg
the error message in case a negative integer is entered.
