ValidationContext class final

Everything a Rule needs to evaluate one attribute (BLUEPRINT_V2 §7.4.1).

Constructors

ValidationContext({required String attribute, required String pattern, required Object? value, required bool present, required Map<String, Object?> data, Container? container, String locale = 'en', bool numeric = false, Set<String> booleans = const <String>{}, Map<String, String> attributeNames = const <String, String>{}})

The context of attribute (the concrete path, such as items.2.id), matched by the rule key pattern, whose value was present in data.

const

Properties

attribute → String

Concrete attribute path (items.2.id).

final

attributeNames → Map<String, String>

The custom attribute names of this validation.

final

booleans → Set<String>

The attributes with a boolean rule (Laravel's shouldConvertToBoolean).

final

container → Container?

Container for rules that need services (unique, exists).

final

data → Map<String, Object?>

The complete input.

final

hashCode → int

The hash code for this object.

no setter, inherited

locale → String

Locale used for messages.

final

numeric → bool

Whether the attribute also carries a numeric or integer rule, so size rules (min, max, between, size) measure a string by its numeric value, as Laravel does.

final

pattern → String

Rule key as written (items.*.id).

final

present → bool

Whether the attribute key exists in the input.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

value → Object?

Current value (null when absent).

final

Methods

displayName(String attribute) → String

attribute as a message shows it.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

root(String path) → Object?

Looks up another attribute by dot path from the root.

sibling(String key) → Object?

Looks up a sibling of the current attribute (items.2.qty from items.2.id when key is qty).

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

dig(Object? source, String path) → Object?

Dot-path lookup supporting list indexes.

exists(Object? source, String path) → bool

Whether path exists in source (a null value still counts).
