Packages

Sixteen libraries you embed directly in your own Dart or Flutter app — or, for structured_log_shelf, your Dart server — install one, import it, and go. (For the self-hosted server and its admin client, see the guides instead.)

Package	What it is
structured_log	The core library — structured JSON logging with context binding, processors, and multi-sink output routing. Start here regardless of platform.
structured_log_flutter	A headless log-viewer core for Flutter: a bounded LogBuffer sink and a filterable LogViewerController. Build your own UI on top of it, or use one of the three skins below.
structured_log_material	A ready-to-use Material 3 in-app log viewer, built on structured_log_flutter.
structured_log_fluent	A ready-to-use Fluent UI (WinUI-style) in-app log viewer, built on structured_log_flutter.
structured_log_cupertino	A ready-to-use Cupertino (iOS-style) in-app log viewer, built on structured_log_flutter.
structured_log_remote_sync	A RemoteSyncLogOutput sink that ships log entries to a structured_log_server instance over HTTP — batching, retry with backoff, a bounded buffer. See the Developer Guide for the full ingestion walkthrough.
structured_log_bloc	A BlocObserver that logs every bloc’s and cubit’s lifecycle, events, state changes and errors as structured_log entries. Works with flutter_bloc as is.
structured_log_riverpod	A ProviderObserver that logs every Riverpod provider’s creation, updates, failures and removal as structured_log entries. Works with flutter_riverpod as is; Riverpod 3 only.
structured_log_dio	A dio interceptor that logs every request and its outcome, with the level following the status code and auth headers, cookies and token-like query parameters redacted.
structured_log_http_client	The same for package:http: a client that wraps any http.Client and logs every call it passes through.
structured_log_go_router	Logs every go_router navigation — location, route pattern, previous location — plus redirects and routing errors, with token-like query parameters redacted.
structured_log_auto_route	Logs every auto_route screen that is opened, closed or switched to — name, pattern, location — with token-like parameters redacted.
structured_log_cherrypick	A CherryPickObserver that logs what the cherrypick DI container does — scopes, modules, cycles, resolve errors — without ever printing an instance.
structured_log_drift	A drift QueryInterceptor that writes every query — SQL, duration, rows — plus batches, failures and transaction ends, flags slow queries and keeps argument values out by default.
structured_log_logging	A bridge that writes every package:logging record as a structured_log entry — message, logger, level by value, error and stack trace — so the logs of libraries that write through package:logging reach the same sinks as your own.
structured_log_shelf	A shelf middleware for a Dart server: one entry per request — method, path, status, duration — and a logger for each handler bound to the request’s request_id, returned in X-Request-Id. Bodies are never written.

Looking for structured_log_http? It was renamed to structured_log_remote_sync (HttpLogOutput → RemoteSyncLogOutput) and is discontinued; its page explains the move.

Each package’s page below is its README verbatim: installation, a quick start, the full feature list, and an API reference table.
