ispectify_db adds passive database observability to the ISpect toolkit. It traces SQL statements, ORM operations, and KV-store calls through a single dbTrace extension with timing, row counts, slow-query detection, and redaction.

• Works with any driver. sqflite, drift, Isar, ObjectBox, shared_preferences, hive, and the rest. Wrap the call and the tracing is automatic.
• Argument redaction by configured keys.
• A slow-query threshold emits a separate log entry so perf outliers stand out.
• Optional stack trace capture on errors, paid for only when an error happens.
• Pure Dart. No Flutter binding required.

Install

dependencies:
  ispectify: ^7.0.0-dev3
  ispectify_db: ^7.0.0-dev3

Quick start

Pass configuration at the traced call site:

import 'package:ispectify_db/ispectify_db.dart';

const dbConfig = ISpectDbConfig(
  sampleRate: 1.0,
  redact: true,
  attachStackOnError: true,
  slowThreshold: Duration(milliseconds: 400),
);

Then wrap each storage call with dbTrace:

import 'package:sqflite/sqflite.dart';

final rows = await ISpect.logger.dbTrace<List<Map<String, Object?>>>(
  source: 'sqflite',
  operation: 'query',
  statement: 'SELECT * FROM users WHERE id = ?',
  args: [userId],
  table: 'users',
  run: () => db.rawQuery('SELECT * FROM users WHERE id = ?', [userId]),
  projectResult: (rows) => {'rows': rows.length},
  config: dbConfig,
);

source and operation become the grouping key in the log viewer. projectResult lets you record "just the counts" instead of dumping row contents.

Configuration

Field	Default	What it does
sampleRate	1.0	Fraction of calls to log. 0.1 keeps 10% of them.
redact	true	Mask sensitive keys in args and statement.
redactKeys	built-in set	Override the redaction key list.
attachStackOnError	true	Capture and log a stack trace on failure.
slowThreshold	null	Re-emit durations above the threshold as a db-slow-query entry. (Renamed from slowQueryThreshold in 5.0.)

const dbConfig = ISpectDbConfig(
  redact: true,
  redactKeys: ['password', 'token', 'secret'],
  slowThreshold: Duration(milliseconds: 250),
);

redactKeys is an explicit local replacement for this trace. Omit it to use the current global ISpectRedaction.service.

Data redaction

Sensitive data is masked before it reaches logs or observers. Redaction is on by default. The built-in rules cover auth headers, tokens, passwords, API keys, cookies, common PII (SSN, passport, driver's license), financial data (credit cards, IBAN), and phone numbers.

The default policy is a single source of truth. Configure it once and core logs, traces, persistence, network and database adapters, BLoC and Riverpod observers, supported exports, clipboard helpers, and cURL generation resolve it when each diagnostic operation runs.

Redaction works best paired with deliberate capture. Use the integration's metadataOnly() or compact preset when payload values are unnecessary, and register project-specific keys for the business identifiers only your application understands.

Global configuration

import 'package:ispectify/ispectify.dart';

ISpectRedaction.configure(
  service: RedactionService(
    additionalSensitiveKeys: {
      'x-custom-secret',
      'internal_token',
    },
    additionalSensitiveKeyPatterns: [
      RegExp(r'my_app_secret_\w+', caseSensitive: false),
    ],
    fullyMaskedKeys: {'filename'},
    placeholder: '***',
    visibleEdgeLength: 3,
  ),
);

additionalSensitiveKeys and additionalSensitiveKeyPatterns extend the built-in policy. Use sensitiveKeys or sensitiveKeyPatterns only when you intentionally want to replace the corresponding defaults:

final replacementPolicy = RedactionService(
  sensitiveKeys: {
    'x-custom-secret',
    'internal_token',
  },
  sensitiveKeyPatterns: [
    RegExp(r'my_app_secret_\w+', caseSensitive: false),
  ],
);

Flutter apps can pass the same policy as ISpect.run(redactionService: ...); ISpect.dispose() restores the policy that was active before that run. An explicit RedactionService supplied to one integration stays local and takes precedence over the global policy. Existing integrations without an explicit service pick up later global reconfiguration. The policy is scoped to the current Dart isolate.

Local exceptions

final redactor = RedactionService(
  ignoredKeys: {'mobile', 'platform_token'},
  ignoredValues: {'<test-token>', 'public-api-key'},
);

Disabling

ISpectRedaction.configure(enabled: false) is the global content-masking opt-out. Each interceptor also accepts enableRedaction: false on its settings object for a local opt-out. Size limits, non-executing snapshots, private-storage checks, and the compile-time ISPECT_ENABLED gate remain enforced.

Only disable redaction in isolated local or deterministic test environments. Exported sessions and observer events should be handled according to the data they contain.

The ISpect toolkit

ISpect is a modular monorepo. Pick the packages your project needs. Each one works on its own.

Package	What it does
ispect	Flutter UI: debug panel, log viewer, navigation observer, inspector integration.
ispect_layout	Visual layout inspector with sizes, constraints, decorations, compare mode, and a color picker.
ispectify	Pure-Dart logging core: typed log entries, filtering, tracing, observers.
ispectify_dio	Dio HTTP interceptor with automatic redaction.
ispectify_http	http package interceptor with automatic redaction.
ispectify_ws	Provider-agnostic WebSocket capture (any client) with automatic redaction.
ispectify_db	Database operation tracing for SQL, ORMs, and KV stores.
ispectify_bloc	BLoC event, state, transition, and error observer.
ispectify_riverpod	Riverpod provider add, update, dispose, and failure observer.
