ArraySchema class Null safety

Schema to validate arrays.

Example

var schema =  ArraySchema(TypeCode.String);

schema.validate(['A', 'B', 'C']);    // Result: no errors
schema.validate([1, 2, 3]);          // Result: element type mismatch
schema.validate('A');                // Result: type mismatch

Constructors

ArraySchema([dynamic valueType, bool? req, List<IValidationRule>? rules])
Creates a new instance of validation schema and sets its values. [...]

Properties

hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited

Methods

getRules() List<IValidationRule>?
Gets validation rules to check values against. [...]
inherited
getValueType() → dynamic
Gets the type of array elements. Null means that elements may have any type. [...]
isRequired() bool
Gets a flag that always requires non-null values. For null values it raises a validation error. [...]
inherited
makeOptional() Schema
Makes validated values optional. Validation for null values will be skipped. [...]
inherited
makeRequired() Schema
Makes validated values always required (non-null). For null values the schema will raise errors. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
performTypeValidation(String? path, dynamic type, dynamic value, List<ValidationResult> results) → void
Validates a given value to match specified type. The type can be defined as a Schema, type, a type name or TypeCode When type is a Schema, it executes validation recursively against that Schema. [...]
inherited
performValidation(String? path, dynamic value, List<ValidationResult> results) → void
Validates a given value against the schema and configured validation rules. [...]
override
setRequired(bool value) → void
Sets a flag that always requires non-null values. [...]
inherited
setRules(List<IValidationRule> value) → void
Sets validation rules to check values against. [...]
inherited
setValueType(dynamic value) → void
Sets the type of array elements. Null means that elements may have any type. [...]
toString() String
A string representation of this object. [...]
inherited
validate(dynamic value) List<ValidationResult>
Validates the given value and results validation results. [...]
inherited
validateAndReturnException(String? correlationId, dynamic value, [bool strict = false]) ValidationException?
Validates the given value and returns a ValidationException if errors were found. [...]
inherited
validateAndThrowException(String? correlationId, dynamic value, [bool strict = false]) → void
Validates the given value and throws a ValidationException if errors were found. [...]
inherited
withRule(IValidationRule rule) Schema
Adds validation rule to this schema. [...]

Operators

operator ==(Object other) bool
The equality operator. [...]
