Stacked on #160 — only the two commits on top are new here.

The logger in stream_core was unreachable: StreamLog was never exported and its defaults dropped every record, so nothing in the repo logged anything. This reworks it and wires it into the WebSocket layer.

Logger

  • StreamLogger is the handle you log with; StreamLogHandler is where records go, installed once on StreamLogger.handler. StreamLogger.priority sets the threshold.
  • Handlers: console, composite, from, debugOnly, silent. Filters: minPriority, prefix, always.
  • StreamLogger.detached gives a component its own destination and threshold; StreamLogger.reset puts the defaults back in tests.
  • A record is a StreamLogRecord carrying the priority, tag, message, time, sequence number, error and stack trace.
  • Priority is now StreamLogPriority, and MessageBuilder is StreamLogMessage.
  • Nothing is written until an app installs a handler, and a message is only built if some handler wants it.
StreamLogger.handler = const StreamLogHandler.console();
StreamLogger.priority = StreamLogPriority.debug;

const _log = StreamLogger('SF:Feed');
_log.d(() => 'loading $id');
_log.e(() => 'failed', error: e, stackTrace: s);

WebSocket

  • The client, engine, health monitor, authentication handler and recovery handler each log under their own tag. Each takes a tag, so a second client's records stay apart from the first's.
  • The engine now reports a frame it cannot decode, and the authentication handler reports the outcome of a superseded attempt. Both were silent before.

613 tests.

stream_video will not compile against this until it drops its own logger, since it exports the same names. It pins stream_core: ^0.4.0, so nothing breaks until it bumps.

📝 Walkthrough

Walkthrough

The PR replaces the logger API with configurable priorities, filters, handlers, and records. It adds tagged logging to HTTP and WebSocket components, updates User.guest, adds package analysis settings, and expands test coverage.

Changes

Stream logging and diagnostics

Layer / File(s) Summary
Logger contracts and runtime flow
packages/stream_core/lib/src/logger*, packages/stream_core/lib/src/logger.dart, packages/stream_core/test/logger/*, packages/stream_core/test/helpers/logger.dart
The logger now uses StreamLogPriority, StreamLogRecord, StreamLogFilter, StreamLogHandler, StreamLogConfig, and attached or detached StreamLogger instances. The former logger implementations and exports were removed.
HTTP authentication and interceptor logging
packages/stream_core/lib/src/api/interceptors/*, packages/stream_core/test/api/interceptors/*
Authentication events and HTTP interceptor output now use tagged logging. LoggingInterceptor can route output through LogPrint or StreamLogger and skips formatting when no consumer is active.
WebSocket lifecycle diagnostics
packages/stream_core/lib/src/ws/client/*, packages/stream_core/test/ws/client/*, packages/stream_core/test/helpers/ws_client_tester.dart
WebSocket components now propagate logging tags and record connection, authentication, health, reconnection, socket, server-error, and decode-failure events.
Package validation and API updates
packages/stream_core/analysis_options.yaml, packages/stream_core/CHANGELOG.md, packages/stream_core/lib/src/user/user.dart, packages/stream_core/lib/src/user/token_manager.dart, packages/stream_core/lib/src/attachment/uploader/attachment_uploader.dart
Package analysis settings and changelog entries were added. User.guest now forwards an optional image parameter. Documentation references were updated.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 806a6

The PR adds WebSocket logging and a new filtering pipeline, but two localized logger behaviors can admit suppressed records or build messages that a handler later discards. The change is mergeable with explicit owner follow-up to correct filtering and avoid unnecessary work.

The logger this replaces was unreachable: its `StreamLog` registry was never exported
and its defaults dropped every record, so nothing in the repo had ever logged anything.

`StreamLogger` is now the tagged handle you write with, matching what `Logger` means in
`package:logging` and `package:logger`. It is const, so a component holds one as a field
and a top-level function holds one in a file with no class — which pure injection cannot
serve, and which is most of where a product logs from.

Where records go is a `StreamLogHandler` an app installs once on `StreamLogger.handler`,
resolved when a record is written rather than when the logger was built, so a logger
created at class-load reaches whatever the app configures later. `StreamLogger.priority`
sets the threshold in one line; `StreamLogFilter.prefix` holds one subsystem to a
different one. `StreamLogger.detached` opts a component out of all of it, and
`StreamLogger.reset` puts the defaults back for a test that installed something.

A record is a `StreamLogRecord`, so fields can be added without breaking every handler.
It is stamped once from `package:clock`: a composite reports one time for one record,
and a test can pin it. It also carries the error and stack trace, which the previous
interface accepted but nothing ever passed.

`Priority` becomes `StreamLogPriority`, keeping its values and gaining `emoji` and
`label`. The old name clashed with the one `package:flutter/scheduler.dart` exports, and
was the only name in the logger without the prefix.

Nothing is written until a handler is installed. Measured on that path: 4.7ns against a
2.0ns empty loop, with no heap growth over twenty million calls, because a message no
handler wants is never built.

BREAKING CHANGE: `StreamLogger` is the handle rather than the destination, and `Priority`
is `StreamLogPriority`. `StreamLog`, `streamLog`, `TaggedLogger`, `IsLoggableValidator`,
`Finder` and `FileStreamLogger` are gone; of those only the last three were exported.
The client, engine, health monitor, authentication handler and recovery handler each
hold a logger, reporting under `SC:WsClient` and, for the three the client owns,
`SC:WsClient:Engine`, `:Health` and `:Auth`. Each takes a `tag` rather than a logger —
the destination is the app's business — so a second client's records stay apart from the
first's, and one prefix still selects a whole family.

Two of these were invisible before. The engine dropped a frame it could not decode
without a word, so a codec mismatch looked like a server that had gone quiet; the
authentication handler discarded the outcome of a superseded attempt just as silently.

State transitions, connect and disconnect reasons, and the computed backoff delay sit at
debug, ping and pong at verbose, so an app that installs a console handler sees only what
is worth acting on until it asks for more.
Every branch in it was silent, including the ones that leave a refused request refused:
no token to sign with, a provider with nothing fresher to give, a request signed for a
user who has since changed, and a replacement the server refused too.

That is the "why do my requests 401 and never recover" path, and until now it produced
nothing to look at.
It defaulted to bare `print`, so an SDK that installed it wrote every request and
response to the console in every build, including release. With `requestHeader` on it
wrote the `Authorization` header too — the interceptor runs after the request is signed,
so a user's token went to the device log unasked. stream_feeds installs it exactly that
way.

Records now go through the logger, so nothing is written until an app installs a handler,
and nothing is formatted either: the twenty-seven lines a request used to produce are not
built while no handler wants them.

BREAKING CHANGE: `LoggingInterceptor.logPrint` is now an optional, final `LogPrint?`.
Leaving it unset routes lines to the logger rather than to `print`.
A product client took the two ambient setters itself, which meant every
SDK reimplemented the same four rules: no config touches nothing, a
priority alone writes to the console, a handler alone hears warnings,
and none silences. Two SDKs remembering them differently would leave the
shared logger holding whichever client was built last.

StreamLogConfig carries them instead, and configure applies it. The
config also carries the filter, because priority and filter are the same
field underneath — a config that set only the priority flattened a
prefix rule the app had installed.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Both settings are one field underneath, so a config naming only a
priority still drops a rule installed through the filter setter. The
place to put the rule is the config, which carries it.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
… from

One logger serves the process, so configuring a client turns logging on
for every Stream SDK in it, and two configured differently settle on
whichever was built last. Neither is guessable from a per-client config,
and the way out — filtering on the prefix the tags already carry — was
only documented as a way to tune a subsystem.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Configuring a client replaced the handler and filter for the whole
process, so a second Stream SDK lost whatever the first installed, and
an app that had set a filter itself lost it to the next client it built.

A config given a scope now settles only the tags starting with it. A
config naming no handler writes wherever the app already installed one,
so asking for records no longer redirects them away from a destination
the app chose.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A tag was already a path — `SF:Ws:Engine` under `SF:Ws` under `SF:` —
but the API called the branch a scope, which reads as an opaque key
rather than as the parent every tag under it inherits from.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…records"

This reverts d87ef5a and 7f78698, returning to one logger for every
product. Scoping a config to a branch of the tag tree bought isolation
at the cost of a handler that resolved through three fallbacks before it
found a destination, which is harder to follow than the behaviour it
was protecting against.

One logger serves the process and the docs say so, including that two
clients configured differently settle on whichever was built last, and
that a prefix filter is what holds one SDK apart from another.

Composing with the default handler is what keeps a console alongside a
crash reporter, and it is also where `debugOnly` earns its place: the
console is the half a user could see, and the crash reporter is the half
worth having in every build.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Three write-only statics said nothing about there being one logger for
the process, and a test could not put back what it found because a
write-only setter cannot be read — which is the only reason `reset`
existed.

`StreamLogger.root` holds both, readably, the way `Logger.root` does in
package:logging. Setting a threshold there still needs a destination
beside it, as it does there; `configure` remains the one call that takes
both, so a product config naming only a priority still reports
somewhere.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…ogger"

This reverts 470f7dd. `StreamLogger.root` was named after `Logger.root`
in package:logging without being what that is: theirs is a logger you
can write through, ours only held a handler and a filter, so the name
promised something the type did not have.

The three setters carry the same settings without claiming to be a
logger.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`console` was the one handler carrying a threshold as a parameter, which
is the shape that silently ate debug records when it defaulted to
warning while the filter said otherwise.

`StreamLogHandler.filtered` holds one destination to a threshold without
the handler comparing priorities itself, so narrowing is written in the
filter vocabulary and works for any handler, not just the console. It
also narrows by tag, which a priority could not express: one SDK's
records can go somewhere the rest do not.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`none` outranks every severity, so a record written at it passed every
`minPriority` filter — including one set to `none`, making it the single
record that shutting logging down could not silence.

Also turns on `comment_references` for this package. Four dartdoc links
were left pointing at members a rename had removed, and nothing noticed;
the rule is off across the repository because `stream_core_flutter` has
642 violations, but this package was already clean but for five.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Writing a record walked the two pieces that gate it and re-derived the
same answer every time, and `priority` and `filter` wrote the same field
by coincidence rather than by saying so.

Installing either now compiles both into a single predicate, so the
write path asks one question, and `priority` is visibly a way of
building a filter rather than a second setting that happens to collide
with one. A detached logger keeps its own pair, having nothing shared to
compile.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A handler answering `isLoggable` meant two things decided what was
logged, and predicting the output meant reasoning about both. A
destination now takes what the filter admitted and discards on delivery
what it does not want, which is what every logger surveyed does.

`debugOnly` goes with it: guessing the build mode from whether
assertions run was core's way of asking a question the app can answer,
and an app naming its handler under `kDebugMode` says it plainly.

Nothing installed is still free — that is not a decision a destination
makes about a record, so the logger settles it rather than asking.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…ound it

A ternary picking between a composite and a lone handler names the other
handler twice, and the list already takes a condition.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`isLoggable` asked the filter and then the handler, so predicting what
was logged meant holding both in mind. It now asks the filter, and
`priority` is the shorthand that installs one.

The filter therefore starts admitting nothing rather than warnings: with
no destination to consult, an open default would have had every SDK
build failure records for an app that never asked, and formatted every
failed request through `LoggingInterceptor`. A destination and a
priority are now both needed, which is what `configure` supplies at once.

Covers the field initialisers too. Every suite restores the defaults
rather than observing them, so a change to what a fresh process starts
with went unnoticed until a mutation exposed it.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Folding the filter and the handler into a single predicate saved a
second virtual call on every write. With the handler no longer deciding
anything, the closure wrapped one filter call and cost a static field, a
compile step, and three places that had to remember to rebuild it.

Reading the filter directly is the same work without the bookkeeping.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Folding the gate into `_effectiveFilter` dropped it, and the default
filter compares `none` against itself, so a record written at the
threshold that means silence was admitted by it.

Also corrects what a detached logger's filter is said to default to: the
ambient one now admits nothing until an app names a priority, so the two
are no longer the same threshold.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The logger refused `none` as a record's priority, which put a rule about
thresholds in the one place that was supposed to delegate them. It also
guarded the wrong end: what matters is that a threshold of `none` admits
nothing, not that a record can never carry it.

Each filter now rejects outright where its threshold is `none`, so
`StreamLogFilter` and `StreamLogger` give the same answer where they
used to disagree, and the logger is back to asking the filter and
nothing else.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every use of the type is a threshold — a filter compares against it, a
setter installs one, a config carries one — and `priority` reads as a
property of the record rather than the bar it has to clear. `level` is
also the word `package:logging`, `logger` and `talker` all use, so the
type now matches the vocabulary a Flutter developer arrives with.

The integer behind it becomes `value`, as `Level.value` is, since
`level.level` said nothing.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
This reverts 68c385d. The values and labels are `android.util.Log`'s,
where the parameter is `int priority`, and Timber — which the tag and
per-severity glyph design came from — calls it that too.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A blank line before each box, and either side of a response body,
separated them when this wrote straight to a console. Every line is now
a record carrying a timestamp and a tag, so the same blanks read as
noise and cost as much to build as any other record.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The convenience constructor took an id and a name and dropped the avatar
the unnamed one accepts, so a guest could only have one by not using it.

Also says what becomes of the id it is given: the server assigns a guest
`guest-<uuid>-<userId>` during connect, so the one passed here survives
only as the tail of it.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…ded a handler

A destination alone reports nothing now that the level starts closed, so
naming only the handler describes a state that never logs.

Reject StreamLogPriority.none in the always filter.

StreamLogPriority.none is documented as a threshold that admits no records. This filter currently reports it as loggable. Keep none non-loggable in every filter implementation.

Proposed fix
-  bool isLoggable(StreamLogPriority priority, String tag) => true;
+  bool isLoggable(StreamLogPriority priority, String tag) => priority != StreamLogPriority.none;

Correct the isLoggable contract.

isLoggable only checks _effectiveFilter. A StreamLogHandler.filtered handler can still reject the record. The documented guard can therefore run expensive work, call message(), and create a record that the handler drops.

Either include handler acceptance in this check or document this method as global-filter admission only. Based on the provided handler contract, StreamLogHandler.filtered can discard admitted records.

182, Update StreamLogger.isLoggable to account for both _effectiveFilter
admission and the configured StreamLogHandler acceptance, so it returns true
only when the record will be retained by both layers. Preserve the documented
guard’s behavior of preventing expensive message construction when
StreamLogHandler.filtered would discard the record.

Wrap the logging example.

Line 58 exceeds the 120-character limit. Split the StreamLogHandler.filtered call across lines.

Proposed fix
-/// StreamLogger.handler = const StreamLogHandler.filtered(StreamLogFilter.minPriority(StreamLogPriority.debug), StreamLogHandler.console());
+/// StreamLogger.handler = const StreamLogHandler.filtered(
+///   StreamLogFilter.minPriority(StreamLogPriority.debug),
+///   StreamLogHandler.console(),
+/// );

As per coding guidelines, “Use a maximum line width of 120 characters, as configured in analysis_options.yaml.”
