Usage

import 'package:ds_logging_base/ds_logging_base_export.dart';
import 'package:ds_otlp_logging_provider/ds_otlp_logging_export.dart';

final otlpConfig = {
  'name': 'otlp',
  'endpoint': 'http://otel-collector:4318/v1/logs',
  'serviceName': 'dartstream-api',
  'serviceVersion': '1.2.3',
  'environment': 'production',
  'headers': {
    'x-api-key': 'your-api-key',
  },
  'resourceAttributes': {
    'deployment.region': 'us-central1',
  },
  'timeout': 2,
};

registerOtlpLoggingProvider(otlpConfig);

final logger = DSLoggingManager('otlp');
await logger.initialize(otlpConfig);

logger.info('Request received', context: {
  'http.method': 'GET',
  'http.path': '/v1/orders',
  'requestId': 'req_123',
});

Configuration

• endpoint (required) - OTLP/HTTP logs endpoint (usually /v1/logs)
• headers (optional)
• serviceName (optional)
• serviceVersion (optional)
• environment (optional)
• resourceAttributes (optional)
• timeout (optional, seconds)

Notes

• Uses OTLP/HTTP JSON payloads for logs.
• Transport errors are swallowed so logging never crashes the app.
