Migration from dio_interceptor_seq

The legacy package dio_interceptor_seq is deprecated in favor of structured_logger + structured_logger_dio_interceptor.

Before (legacy)

import 'package:dio/dio.dart';
import 'package:dio_interceptor_seq/dio_interceptor_seq.dart';

final dio = Dio()..interceptors.add(SeqLoggingInterceptor(
  'https://seq.example.com',
  apiKey: 'key',
  deviceIdentifier: 'my-app',
  correlationalHeaderName: 'X-Request-Seq-Id',
));

After (recommended)

import 'package:dio/dio.dart';
import 'package:structured_logger/structured_logger.dart';
import 'package:structured_logger_dio_interceptor/structured_logger_dio_interceptor.dart';

final logger = StructureLogger()
  ..addSink(SinkSeq(
    'https://seq.example.com',
    apiKey: 'key',
    deviceIdentifier: 'my-app',
  ));

final dio = Dio()..interceptors.add(DioLoggingInterceptor(logger));

Key differences

• Package + class names changed.
• seqUrl / apiKey / deviceIdentifier now belong exclusively to SinkSeq.
• Interceptor receives StructureLogger (already wired to any sinks you want).
• Same event shapes (REQUEST/RESPONSE/ON_ERROR), templates and headers.
• No direct Seq calls from interceptor; fully decoupled.
• Use dart pub add structured_logger structured_logger_dio_interceptor.

In monorepo context

See packages/structured_logger_dio_interceptor and the Dio guide for details.
