Integer class

The Integer Rule.

Validates that the field is an integer, an integer-looking string, or a double with no fractional part. Mirrors Laravel's integer rule (FILTER_VALIDATE_INT), which passes a float like 5.0 because PHP casts it to the string "5" before filtering; a Dart double gets the same answer here by checking it against its own truncated value instead.

Usage

validate(data, {
  'quantity': [Required(), Integer()],
});
