en_logger 2.0.0

EnLogger allows you to write log messages according to your needs without restricting you to writing messages to the debug console or other systems.

2.0.0 - 2026-05-28

Added

• BREAKING: Handler.write now receives additional parameters: error, tags, eventId, timestamp, and sequenceNumber.
• Core Observability Enhancements: Every log event now automatically generates and forwards the following to the Handler:
  • A unique eventId.
  • A callerInfo, where the user call the log method
  • A isolateName, the debugName of the isolate where the log method is executed
  • A timestamp, captured immediately before any async queueing or lazy processing.
  • A globally incrementing sequenceNumber to guarantee the absolute chronological creation order of the logs.
• Error Disambiguation: Separated the error object from the text message for logs with a severity of error or higher by introducing a dedicated error property.
• Tags: Added tags, an optional map of additional encodable key-value pairs to attach to log messages.
• Zone Context Extraction: Added zoneContextKeys. EnLogger can now automatically extract specified keys from the current Zone, merge them with method-specific tags, and forward the unified map to the Handler.

Changed

• Breaking: Rename PrinterHandler to DevLogHandler, PrinterColorConfiguration to DevLogColorConfiguration, PrinterColor to DevLogColor
• Preserve logs order (fifo) when lazy methods are used
