isAfter method Null safety

String? isAfter(
  1. String? value,
  2. {String? message,
  3. required dynamic min}
)

Check if the value (a Date) is after the given Date.

Implementation

static String? isAfter(String? value, {String? message, required min}) => value == null || value.isEmpty || validations.isAfter(value, min) == true
    ?  null
    : message ?? 'Please enter a date after ${min.runtimeType.toString() == 'DateTime' ? min.toString().substring(0, 10) : min}';
