ispectify_http is an http_interceptor interceptor for the ISpect toolkit. It captures requests made through the package:http client, pairs them into transactions, and redacts sensitive data before logging.

• Request, response, and error capture with headers, body, status, and duration.
• Redaction of auth headers, tokens, PII, and financial data. On by default.
• Works with any InterceptedClient from http_interceptor.

Install

dependencies:
  http: ^1.0.0
  http_interceptor: ^2.0.0
  ispectify: ^7.0.0-dev3
  ispectify_http: ^7.0.0-dev3

Quick start

import 'package:http_interceptor/http_interceptor.dart' as http_interceptor;
import 'package:ispect/ispect.dart';
import 'package:ispectify_http/ispectify_http.dart';

final client = http_interceptor.InterceptedClient.build(interceptors: []);

ISpect.run(
  () => runApp(const MyApp()),
  logger: logger,
  onInit: () {
    client.interceptors.add(
      ISpectHttpInterceptor(
        logger: logger,
      ),
    );
  },
);

Register ISpectHttpInterceptor last in the interceptors list. Request/response correlation is keyed on the BaseRequest instance, and http_interceptor lets each interceptor return a new request object. If an interceptor registered after it rebuilds the request, the response can't be matched and stays "Pending".

Settings

ISpectHttpInterceptorSettings mirrors the Dio version. Headers and bodies are captured and redacted by default, and enableRedaction defaults to true.

const settings = ISpectHttpInterceptorSettings(
  logRequests: true,
  logResponses: true,
  printRequestHeaders: true,
  printRequestData: true,
  printResponseHeaders: false,
  printResponseData: true,
  enableRedaction: true,
);

Preset factories and a builder are also available. Use ISpectHttpInterceptorSettingsBuilder.metadataOnly() to retain request and response metadata while omitting bodies and headers. The development(), staging(), and production() presets remain available for environment-based policies.

logRequests and logResponses control whether routine records are retained; the production preset disables both and keeps redacted errors. The print* flags can omit bodies, headers, or messages from retained console and metadata fields. Full capture is the default and keeps redaction on; individual flags and the metadataOnly() preset provide opt-in minimization. Use the concrete settings copyWith or builder for these retention controls; the shared base configure helper retains its legacy-compatible field set.

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.

Custom redactor:

ISpectHttpInterceptor(
  logger: logger,
  redactor: RedactionService(
    additionalSensitiveKeys: {'x-internal-token'},
  ),
);

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.
