flutter_password_scoring 0.2.0+2

Helper library to score password strength with `dart_zxcvbn` and provide suggestions for improvement.

flutter_password_scoring

❗ THIS PACKAGE IS STILL WORK IN PROGRESS ❗

Description

The primary goal of this package is to support dart_zxcvbn in Flutter.

This package supplies two kinds of password scoring handlers. The default one PasswordScoringHandler doesn't use Isolates, so everything runs on main thread. It is Web friendly (remember no Isolates on Web platform in Flutter), but it also can block main thread for long time. As an alternative there's also Isolate based handler which you can use on mobile on native platform.

Usage

Use PasswordScoringBuilder to build your UI. Take a look at example code if you wan't to customize dictionaries and other options based on Locale.

/// Keep in mind that when using Isolate based handler it's
/// crucial to keep it final in state, so it won't be
/// recreated on every call to [build].
final handler = kIsWeb
    ? PasswordScoringHandler()
    : PasswordScoringIsolateHandler();

PasswordScoringBuilder(
  handler: handler,
  loadingPlaceholder: const Center(
    child: CircularProgressIndicator(),
  ),
  builder: (
    BuildContext context,
    Result? data,
    PasswordScoringHandler handler,
  ) {
  /// Call [handler.update] every time user entered password changes
  return Placeholder();
  },
);
