dart_seq 3.0.0

A Dart logging client for (batched) Seq HTTP ingestion with automated retries.

3.0.0

• BREAKING: SeqLogger.log() - exception and context changed from positional to named parameters
• BREAKING: SeqLogger convenience methods (verbose, debug, info, warning, error, fatal) - same positional-to-named migration
• BREAKING: SeqEvent constructor - all parameters except timestamp are now named
• BREAKING: SeqClient.sendEvents() - return type changed from Future<void> to Future<List<SeqEventResult>>
• BREAKING: Update SDK constraint to ^3.8.0
• FEAT: SeqEventResult class - per-event success/failure result with isPermanent flag
• FEAT: throwOnError flag (#14) - when false (default), flush errors are caught and reported via onDiagnosticLog; when true, they propagate to caller
• FEAT: onFlushError callback - handler invoked when flush fails; receives failed events and error, returns events to re-queue
• FEAT: SeqClientException.isRetryable - allows implementations to signal non-retryable errors (e.g. 413 Payload Too Large)
• FEAT: OpenTelemetry / distributed tracing fields (#10) - 7 new CLEF fields on SeqEvent: traceId (@tr), spanId (@sp), parentSpanId (@ps), spanStart (@st), scope (@sc), resourceAttributes (@ra), spanKind (@sk)
• FIX: Known Seq CLEF keys (@tr, @sp, etc.) are no longer double-escaped in context
• FIX: Exception formatting (#11) - @x field now uses toString() with safe fallback instead of Error.safeToString()
