PasswordNode<T extends String> class

A validator node for validating passwords (strings with specific strength rules).

Supports a fluent chainable API for validating password length, complexity, repetition, and character requirements.

Example:

final validator = Checkit.string
  .password()
  .min(8)
  .hasUppercase()
  .hasLowercase()
  .hasDigit()
  .hasSpecial()
  .noRepeats()
  .build();

final result = validator.validate("Pa$$w0rd!");
print(result.isValid); // true

Methods

any(List<Validator<T>> validators, {String? error}) → PasswordNode<T>
inherited
build({ValidationContext? context}) → ValidatorSet<T>
Finalizes the validator into a reusable set.
inherited
clone({ValidationContext? context}) → PasswordNode<T>
Clones this node with an optional different context.
override
custom(bool validate(T value, ValidationContext context), {String error = ''}) → PasswordNode<T>
Adds a custom validator using a function.
inherited
every(List<Validator<T>> validators, {String? error}) → PasswordNode<T>
inherited
exact(int length, {String? error}) → PasswordNode<T>
Requires the password to have exactly length characters.
hasDigit({String? error}) → PasswordNode<T>
Requires at least one digit (0-9).
hasLetter({String? error}) → PasswordNode<T>
Requires at least one letter (either lowercase or uppercase).
hasLowercase({String? error}) → PasswordNode<T>
Requires at least one lowercase letter (a-z).
hasSpecial({String? allowedChars, String? error}) → PasswordNode<T>
Requires at least one special character such as !@#\$%^&*.
hasSymbols(String symbols, {String? error}) → PasswordNode<T>
Requires the password to contain at least one character from the given symbols string.
hasUppercase({String? error}) → PasswordNode<T>
Requires at least one uppercase letter (A-Z).
max(int length, {String? error}) → PasswordNode<T>
Requires the password to have a maximum number of characters.
min(int length, {String? error}) → PasswordNode<T>
Requires the password to have a minimum number of characters.
noRepeats({String? error}) → PasswordNode<T>
Disallows repeating characters in a row.
noSpace({String? error}) → PasswordNode<T>
Disallows whitespace characters ( , \t, etc.) in the password.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
not(Validator<T> validator, {String? error}) → PasswordNode<T>
Negates another validator.
inherited
simple({String? error}) → PasswordNode<T>
Validates that the password is simple.
strong({String? error}) → PasswordNode<T>
Validates a strong password with stricter requirements.
toString() → String
A string representation of this object.
inherited
typical({String? error}) → PasswordNode<T>
Validates a typical secure password structure.
validateOnce(T? value, {bool? stopOnFirstError}) → ValidationResult
Quick validation without manually building the set.
inherited
withContext(ValidationContext context) → PasswordNode<T>
Shortcut to clone with updated context.
