Provides a clean, readable API for common patterns:

final validator = Validate.all<String, String>([
  rule1,
  rule2,
]);

Static Methods

all<T, E>(List<Formix<T, E>> validators) → Formix<T, E>

Creates a validator that requires ALL rules to pass (AND logic).

allCollect<T, E>(List<Formix<T, E>> validators) → Formix<T, E>

Creates a validator that requires ALL rules to pass, collecting all errors.

allCollectLimited<T, E>(List<Formix<T, E>> validators, {int maxErrors = 5}) → Formix<T, E>

Creates a validator that requires ALL rules to pass, collecting up to maxErrors errors.

any<T, E>(List<Formix<T, E>> validators, {E? fallbackError}) → Formix<T, E>

Creates a validator that requires AT LEAST ONE rule to pass (OR logic).

cached<T, E>(Formix<T, E> validator) → CachedFormix<T, E>

Creates a single-value cached validator wrapper.

chain<T, E>(List<Formix<T, E>> validators) → Formix<T, E>

Creates a validator that chains validators sequentially.

lazy<T, E>(Formix<T, E> factory()) → LazyFormix<T, E>

Creates a lazy validator that defers instantiation until first use.

lruCached<T, E>(Formix<T, E> validator, {int maxSize = 10}) → LruCachedFormix<T, E>

Creates an LRU cached validator wrapper.

transform<TIn, TOut, E>({required TOut? transform(TIn value), required E onNull, required Formix<TOut, E> then}) → Formix<TIn, E>

Creates a transform validator that parses input before validation.

when<T, E>({required bool condition(T value), required Formix<T, E> then, Formix<T, E>? orElse}) → Formix<T, E>

Creates a conditional validator.
