An extension for dart_seq that provides a local database for log events using Hive.


  • Provides an implementation of SeqCache from dart_seq
  • Stores events on disk until flush is called on the logger
  • Preserves events between sessions (useful for troubleshooting)

Getting started

Install both dart_seq and dart_seq_hive_cache:

dart pub add dart_seq dart_seq_hive_cache


final cache = await SeqHiveCache.create();

final logger = SeqLogger.http(
  host: "http://localhost:5341",
  cache: cache,

await logger.log(SeqLogLevel.information, "before loop");

for (var i = 0; i < 10; i++) {
  await logger.log(SeqLogLevel.information, i.toString());

  print('events in cache: ${cache.count}');

  await Future.delayed(const Duration(seconds: 1));

await logger.log(SeqLogLevel.information, "after loop");

await logger.flush();
