Authentication Service

• [NEW] Added AuthenticationStatus.unknown as the new default authentication state (replaces unauthenticated as default).
• [NEW] Added AuthenticationStatus.isUnknown getter to explicitly check for unknown state.
• [CHANGE] AuthenticationStatus.isUnauthenticated now returns true for both unauthenticated and unknown states (use isUnknown to distinguish).
• [CHANGE] ArcaneAuthenticationService now initializes with AuthenticationStatus.unknown instead of unauthenticated.
• [CHANGE] ArcaneAuthenticationService.reset() now resets status to unknown.
• [CHANGE] Updated tests to reflect new default status behavior.

Arcane Framework

• [BREAKING] This package no longer exports the Error and Ok symbols from the result_monad package.

Migration Steps (Error/Ok)

1. Add the result_monad package to your pubspec.yaml file.
2. Use the import import 'package:result_monad/result_monad.dart'; to access Error and Ok symbols.

Arcane Framework

• [NEW] Added Arcane.service typed lookup entrypoint for provider-aware service access:
  • Arcane.service.ofType<T>(context)
  • Arcane.service.requiredOfType<T>(context)

Logging Service

• [NEW] Added LogInterceptorCallback typedef and updated LogInterceptor callback-based APIs to use the shared callback type alias.

Logging Service

• [CHANGE] LogEvent JSON serialization now delegates recursive nested metadata / extra encode-decode handling to arcane_helper_utils JSON extensions (toJsonValue, toJsonMap, fromJsonValue, fromJsonMap).
• [CHANGE] Refactored LogInterceptor to an interface-style contract with a factory constructor for callback interceptors, so reusable class-based interceptors can be implemented without superclass callback plumbing.

Logging Service

• [BREAKING] Replaced the @LoggingFeature(...) annotation (compile-time only, not readable at runtime in Flutter) with the LoggerName mixin. Mix LoggerName into a LoggingInterface subclass and override name to expose a runtime-accessible name inside log().

Migration Steps (LoggingFeature)

1. Replace any @LoggingFeature("...") annotation with with LoggerName and add an @override String get name => '...'; getter to the class body.

Before:

@LoggingFeature("my-feature")
class MyLogger extends LoggingInterface {...}

After:

class MyLogger extends LoggingInterface with LoggerName {
  @override
  String get name => "my-feature";
}

Arcane Framework

• [NEW] ArcaneApp now owns and publishes a live service registry for provider-aware static lookups.
• [CHANGE] Arcane.features, Arcane.auth, Arcane.theme, and Arcane.environment now prefer the live ArcaneApp registry instance when available, then fall back to built-in singletons.
• [BREAKING] Arcane is now a static utility surface (no instantiable singleton constructor).
• [BREAKING] Several package:arcane_framework/src/... import paths changed (for example, src/providers/... -> src/service/... and src/services/reactive_theme/... -> src/services/theme/...). Consumers importing from src directly must update import paths.
• [NEW] Added optional ArcaneApp.builder callback (TransitionBuilder style) for capturing provider-aware build contexts from within ArcaneApp.
• [DEPRECATED] ArcaneApp.child is now deprecated in favor of ArcaneApp.builder (legacy child usage remains supported during migration).
• [DEPRECATED] BuildContext.serviceOfType<T>() is now deprecated in favor of BuildContext.service<T>().

Environment Service

• [NEW] Added ArcaneEnvironmentService as a singleton ArcaneService instance.
• [CHANGE] Changed ArcaneEnvironment is no longer a Cubit and is now an InheritedWidget.
• [NEW] Added Arcane.environment shortcut for direct environment access.
• [NEW] Added environment service to Arcane.services built-in list.
• [CHANGE] ArcaneEnvironmentProvider is now a StatefulWidget instead of a StatelessWidget with a BlocProvider.
• [NEW] ArcaneEnvironmentProvider now provides methods for enableDebugMode(), disableDebugMode() and setEnvironment().
• [NEW] Added environmentChanges stream for realtime environment updates.

Migration Steps (ArcaneEnvironment)

1. The state getter has been removed from ArcaneEnvironment. If you previously accessed environment state via Arcane.environment.state, update your code to use the new API:

   • Before:

     final env = Arcane.environment.state;
     

   • After:

     final env = Arcane.environment.current;
     

2. If you were using Cubit-style APIs, migrate to the new InheritedWidget/ValueNotifier-based approach. See the README for updated usage examples.

Authentication Service

• [BREAKING] ArcaneAuthInterface.logout now accepts optional onLoggedOut callback parameters. ArcaneAuthInterface implementers must update logout signature to accept optional onLoggedOut. See the migration steps for further details.
• [NEW] Added statusChanges stream to observe AuthenticationStatus updates.
• [NEW] Added signedInChanges stream to observe sign-in state changes.
• [FIX] Added stream lifecycle cleanup in dispose with safe lazy recreation.

Migration Steps (ArcaneAuthInterface)

1. Update ArcaneAuthInterface implementations to accept the new optional onLoggedOut callback parameter in logout(...).
2. If your implementation performs cleanup side effects on logout, invoke onLoggedOut when provided.
3. Run tests to confirm your authentication adapter still satisfies your login/logout flows.

Before:

@override
Future<Result<void, String>> logout() async {
  // ...
  return Result.ok(null);
}

After:

@override
Future<Result<void, String>> logout({
  Future<void> Function()? onLoggedOut,
}) async {
  // ...
  if (onLoggedOut != null) await onLoggedOut();
  return Result.ok(null);
}

Feature Flag Service

• [CHANGE] Renamed service class ArcaneFeatureFlags to ArcaneFeatureFlagService.
• [NEW] Added backward compatibility typedef: typedef ArcaneFeatureFlags = ArcaneFeatureFlagService.
• [NEW] Added enabledFeaturesChanges stream to observe enabled feature updates in realtime.
• [FIX] Added stream lifecycle cleanup in dispose with safe lazy recreation.
• [NEW] Added ArcaneFeatureFlagProvider (InheritedWidget) and ArcaneFeatureFlagsProvider (StatefulWidget) for first-class feature-flag integration in the widget tree.
• [DEPRECATED] ArcaneFeatureFlagsScope has been renamed to ArcaneFeatureFlagProvider.
• [NEW] Added BuildContext convenience accessors for feature flags, including context.featureFlags, context.maybeFeatureFlags, context.isFeatureEnabled(...), and context.isFeatureDisabled(...).
• [NEW] ArcaneApp now includes ArcaneFeatureFlagsProvider by default, enabling rebuilds for widgets that depend on ArcaneFeatureFlagProvider.of(context).
• [UPDATE] README now documents ArcaneFeatureFlagProvider and ArcaneApp provider composition.

Theme Service

• [CHANGE] Renamed ArcaneReactiveTheme to ArcaneThemeService for clearer naming.
• [NEW] Added backward compatibility typedef: typedef ArcaneReactiveTheme = ArcaneThemeService.
• [FIX] Theme initialization now respects ThemeMode.system and initializes ThemeData using the effective brightness.
• [FIX] ArcaneThemeSwitcher now initializes system-follow behavior once on first dependency resolution.
• [FIX] ArcaneThemeSwitcher now defaults to followSystemTheme(context) when mounted under ArcaneApp, so system-follow is enabled by default and system brightness changes are handled framework-side (no app-level observer needed).
• [FIX] switchTheme() now toggles from the effective theme when current mode is ThemeMode.system (system dark -> light, system light -> dark).
• [CHANGE] context.isDarkMode now reflects effective app theme brightness (Theme.of(context).brightness) instead of raw platform brightness.
• [FIX] followSystemTheme() now reads platform brightness directly to avoid coupling system-follow behavior to app theme overrides.
• [NEW] Added assignment-style theme setters: Arcane.theme.dark = ... and Arcane.theme.light = ... (in addition to setDarkTheme / setLightTheme).
• [FIX] Reactive theme stream controllers now close only during service dispose, preventing stream shutdown when a single subscriber cancels.
• [FIX] Setting a theme (e.g., dark) while in the opposite mode (e.g., light) no longer changes the current brightness or rendered theme. Only the active mode's theme updates the rendered appearance.
• [NEW] Added themeModeChanges and themeDataChanges streams for realtime theme updates.

Migration Steps (ArcaneThemeService)

1. Replace legacy ThemeMode reads from Arcane.theme.systemTheme.value with Arcane.theme.currentModeOf(context) when configuring app themeMode.

Before:

MaterialApp(
  theme: Arcane.theme.light,
  darkTheme: Arcane.theme.dark,
  themeMode: Arcane.theme.systemTheme.value,
)

After:

MaterialApp(
  theme: Arcane.theme.light,
  darkTheme: Arcane.theme.dark,
  themeMode: Arcane.theme.currentModeOf(context),
)

Arcane Logger

• [NEW] Added logStream for realtime log subscriptions.
• [NEW] Added explicit dispose cleanup for logger stream resources.
• [NEW] Added optional lifecycle capability via LoggingInitializable and LoggingInitialization.
• [NEW] Added optional feature tag support via @LoggingFeature(...) annotation.
• [NEW] Added a skipAutodetection parameter to Arcane.log (defaults to false) that, when enabled, skips detection of the module, method, and file/line number where logs originated from.
• [NEW] Added the LogInterceptor class which can (optionally) be added to ArcaneLogger to pre-process log messages before they are sent to the registered ArcaneLoggingInterface(s).
• [NEW] Added collection-style interceptor APIs: Arcane.logger.interceptors.add(...), Arcane.logger.interceptors.remove(...), and Arcane.logger.interceptors.clear() with an optional matcher for explicit type-scoped matching strategies, including subtype-inclusive matching.
• [CHANGE] Updated Arcane.log metadata type from Map<String, String>? to Map<String, Object?>? to support structured metadata values.
• [CHANGE] initializeInterfaces() now initializes only interfaces that implement LoggingInitializable; other interfaces are skipped.
• [BREAKING] LoggingInterface no longer includes built-in singleton-style initialization state.

Migration Steps (LoggingInterface)

1. Remove initialized and init from interfaces that do not require startup work.
2. If an interface requires startup/lifecycle management, add LoggingInitialization (or implement LoggingInitializable) and move setup logic into init().
3. Update log(...) implementations to guard behavior with initialized only for interfaces that opted into initialization.
4. Run tests to verify interface registration and logging behavior still match expectations.

Before:

class DebugConsole implements LoggingInterface {
  @override
  bool get initialized => true;

  @override
  Future<LoggingInterface?> init() async => this;

  @override
  void log(String message, {Map<String, Object?>? metadata, Level? level}) {}
}

After:

class DebugConsole extends LoggingInterface {
  @override
  void log(String message, {Map<String, Object?>? metadata, Level? level}) {}
}

• For SDK-backed loggers, opt into initialization with the mixin.

class ExternalLogger extends LoggingInterface with LoggingInitialization {
  @override
  Future<void> init() async {
    if (initialized) return;
    // Start SDK.
    await super.init();
  }

  @override
  void log(String message, {Map<String, Object?>? metadata, Level? level}) {
    if (!initialized) return;
    // Send to SDK.
  }
}

• If desired, adopt feature for destination-aware filtering in interceptors.

Migration Steps (Arcane.log metadata)

1. Update Arcane.log(...) call sites that stringify metadata values only to satisfy the previous Map<String, String> type.
2. Prefer passing native values (for example int, bool, List, or nested Map) directly in metadata when useful.
3. If your logging destination expects only string metadata, convert Object? values to strings at your logging boundary.

Before:

Arcane.log(
  "Login attempt",
  metadata: {
    "attempt": attempt.toString(),
    "rememberMe": rememberMe.toString(),
  },
);

After:

Arcane.log(
  "Login attempt",
  metadata: {
    "attempt": attempt,
    "rememberMe": rememberMe,
  },
);

Dependencies

• [CHANGE] Updated result_monad from ^2.3.2 to ^4.0.0.
• [CHANGE] Removed direct flutter_bloc dependency.
• [CHANGE] Updated collection from ^1.18.0 to ^1.19.0.

• Version redacted. Use v2.0.1.

• Updated dependencies to latest

• Updated dependencies to latest

• Improved automatic metadata detection in ArcaneLogger

• Update package dependencies

• Added ValueNotifiers to both the ArcaneAuthenticationService and ArcaneFeatureFlags. This enables the possibility of listening for changes to either service.

Example

// Listen to changes in the authentication status
Arcane.auth.isSignedIn.addListener(() {
  if (Arcane.auth.isSignedIn.value) {
    Arcane.log("User is signed in");
  } else {
    Arcane.log("User is signed out");
  }
});

// Listen to changes in the enabled/disabled features
Arcane.features.notifier.addListener(() {
  Arcane.log("Enabled features have been updated: ${Arcane.features.notifier.value}");
});

• Lowered minimum required collection dependency version to prevent forcing users into the latest Flutter release

• Lowered minimum required SDK version to prevent forcing users into the latest Flutter release

• Removed flutter_secure_storage dependency as it was unused

Breaking Changes

The following methods have been moved outside of the ArcaneAuthInterface base class:

• resendVerificationCode
• register
• confirmSignup
• resetPassword

These methods have been moved to mixin classes. To continue using them, please update your ArcaneAuthInterface implementations.

• To use resendVerificationCode, register and confirmSignup, use the new ArcaneAuthAccountRegistration mixin.
• To use resetPassword, use the new ArcaneAuthPasswordManagement mixin.

Migration

In order to migrate your existing interfaces, update them from:

class MyAuthInterface implements ArcaneAuthInterface {}

to:

class MyAuthInterface
    with ArcaneAuthAccountRegistration, ArcaneAuthPasswordManagement
    implements ArcaneAuthInterface {}

If the methods that these mixins provide are not being used, the mixins can safely be omitted. If only one of these mixins is required, the other can be safely omitted.

This change should result in fewer lines of code for interface implementations that do not require these additional features.

• Fixed an issue with the ArcaneAuthenticationService where an exception would be thrown when attempting to access an authentication token while no ArcaneAuthInterface was registered.

• Updated logging feature to indicate the feature which was enabled or disabled within the log message, instead of only in the metadata.

• Update package dependencies. No code changes.

• Update package dependencies. No code changes.

• Arcane Auth no longer throws exceptions when log out fails, instead returning a Result<void, String>. This behavior matches the login method.

• Removed Flutter exception handling from ArcaneLoggingService, as this functionality should be defined by a users' interface.

Migration

Add the following to your ArcaneLoggingInterface's init method to replicate the previous behavior:

// Handles unhandled Flutter errors by logging them.
FlutterError.onError = (errorDetails) {
  Arcane.log(
    errorDetails.exceptionAsString(),
    level: Level.error,
    module: errorDetails.library,
    stackTrace: errorDetails.stack,
  );
};

// Handles unhandled platform-specific errors by logging them.
PlatformDispatcher.instance.onError = (error, stack) {
  Arcane.log(
    "$error",
    level: Level.error,
    stackTrace: stack,
  );
  return false;
};
