-
ValidationData
-
Represents data used for validation, including the value to be validated
and a list of validator annotation.
Functions
-
assertNullableString({dynamic value, bool allowNullable = false})
→ void
-
Asserts that the given
value is a String,
and optionally allows null if specified.
-
assertNumeric({dynamic value, bool allowNullable = false})
→ void
-
-
validateField(dynamic value, List<ValidatorAnnotation> annotations)
→ String?
-
Validates a field using a list of ValidatorAnnotation annotations.
