basic_logger

Added

• Documentation: Added an advanced README section on capturing named third-party Logger instances from package:logging.
  • Clarified that all OutputLogger-based sinks (OutputLogger, DevOutputLogger, FileOutputLogger) support named-logger capture.
  • Added observability-focused guidance for common third-party integrations (HTTP SDKs, Database SDKs, Message Queue SDKs, and other infrastructure clients).
  • Included a practical example using a named logger (GoogleAI.HTTP) and sample output.

Added

• Documentation: Added an "Advanced Usage" section to the README.
  • Provided a level mapping reference between Dart logging and other common languages.
  • Demonstrated how to access the native Logger instance for full API flexibility.
  • Included examples for integrating Flutter's global error handlers (FlutterError.onError, PlatformDispatcher) with BasicLogger.

Improved

• Clarified the relationship between BasicLogger and the standard package:logging ecosystem.

• perf: use conditional constructor termination to share a unified data type while bypassing redundant base-class logic during inheritance.

• docs: add multi-sink and log routing patterns to README.
• fix: detachLogger, concurrent modification during iteration.

• BREAKING: DevOutputLogger, uses positional arguments, passing parentName in the same way as its parent.
• fix: If selfonly is false, all logs with a parentName match are output.

• The logger name is set to selfname.
• selfonly, when true, filter by selfname. Otherwise, output all.

• Refactored with Template Method pattern,
• allowing customization of record and format methods.

• supports all six platforms, with file logging separated for non-web platforms.

• new, logrec, log message at the specified level.

• Initial version.
