flex_logger 1.0.1

A flexible logging package for Flutter applications with support for multiple logging strategies, observers, and integrations.

1.0.1

• Fixed FlexLogLevel.fromKey falling back to debug for unknown keys — it now returns error.
• Removed MultiTypeFilter. Use CompositeLogFilter.or([TypeFilter<A>(), TypeFilter<B>()]) instead.
• Added initializing lifecycle state to FlexLogger — concurrent initialize() calls are now ignored instead of running in parallel.
• FlexLogger.initialize() now disposes already-initialized providers and resets to configured on failure.
• FlexObserver callbacks (onLog, onException, onError) are now Future<void>.
• CompositeObserver dispatches all observers concurrently via Future.wait; a failure in one observer no longer affects others.

1.0.0

• Initial public release
• Singleton API: FlexLogger.instance with configure(), initialize(), dispose()
• Logger interface for unified API (main thread, isolate, or custom implementations)
• Multiple log levels: debug, info, success, warning, error, critical
• Provider pattern: LoggerProvider (providerId, initialize, createObserver, dispose) for extensible observers
• FlexObserver with optional per-observer filter; callbacks onLog, onException, onError
• Custom log types: extend FlexLog, send via logCustom()
• Filtering: LogFilter and built-in filters (MinLevelFilter, TypeFilter, DevelopmentOnlyFilter, CompositeLogFilter, AcceptAllFilter, RejectAllFilter)
• CompositeObserver for combining multiple observers
• LogFormatter interface for custom output formatting
• Exception handling: error and stackTrace on log calls; FlexLoggerException, LoggerInitializationException
