0.0.1+3

Released: 2026-05-09

Improvements

• Updated package description in pubspec.yaml for better SEO on pub.dev.

0.0.1+2

Released: 2026-05-09

Bug Fixes

• Fixed query parameter duplication when continuing a paused request.
• Fixed a bug where interception rules disappeared from the DevTools UI after navigating to a different tab.
• Fixed FormData serialization so multipart requests are now properly readable as JSON in the DevTools panel.

Improvements

• Improved text selectability across the DevTools UI (URLs, headers, and query parameters can now be highlighted and copied).
• URLs are now properly decoded for better readability in the request list and detail view.
• Added a "Supported HTTP Clients" table to the README, detailing planned support for graphql_flutter, chopper, and grpc.

Initial public release of Interceptify.

Core Library

Multi-client network interception

• InterceptifyDioInterceptor — QueuedInterceptor implementation for Dio; captures requests, responses, and errors
• InterceptifyHttpClient — BaseClient wrapper for package:http; drop-in replacement for http.Client()

Request lifecycle tracking

• Unique request ID assigned to every intercepted request
• Start-time and duration measurement for response timing
• clientType field ('dio' | 'http') attached to every event for client-level differentiation

Pause / Resume / Cancel

• Pause any request or response using the Rules Engine or global toggle
• Completer-based async mechanism ensures the request is held until DevTools sends a continue or cancel signal
• Configurable timeout (default 30 s) auto-resumes the request if DevTools disconnects

Rules Engine

• Add, remove, and clear intercept rules programmatically or via DevTools UI
• Rule conditions: urlContains, urlEquals, urlStartsWith, methodEquals
• Global toggles: pause all requests, pause all responses, disable all interception

DevTools Bridge

• Full integration with Dart VM Service via dart:developer extension registration
• Registered extensions: getPendingRequests, continueRequest, cancelRequest, addRule, removeRule, clearRules, toggleInterception, getInterceptionStatus, togglePauseAll, togglePauseAllResponses, continueResponse, retryRequest, getTimeout, setTimeout
• Events streamed to DevTools: requestEvent, responseEvent, errorEvent

Safety

• All interception is guarded by kDebugMode; zero overhead in release builds
• No network calls, logging, or side-effects in production

DevTools Extension

Request List — Advanced Filters

• Full-text search by URL and HTTP method (literal or regex mode)
• Regex mode with real-time invalid-pattern indicator
• Method chip filter (GET / POST / PUT / PATCH / DELETE), multi-select

• Duration filter: Any / < 100ms / 100–500ms / > 500ms
• "Failed only" toggle (status ≥ 400 or error)
• Active filter chips displayed below the panel with individual dismiss buttons

Smart Auto Grouping (Charles Proxy-style)

• Default mode: flat list
• Switchable to grouped mode via List / Grouped toggle in the summary bar
• Five grouping strategies available from a dropdown:
  • By Domain (hostname)
  • By Path Prefix (first URL path segment)
  • By Method (HTTP method)
  • By HTTP Client (Dio / HTTP)
  • By Status Code family
• Group headers show request count badge and red error count badge

Request Detail View

• Headers tab: editable request headers, read-only response headers
• Body tab: editable request body with JSON syntax view
• Response tab: response body, status code, duration
• Interactive JSON viewer with node-level expand/collapse and copy
• Copy as cURL button
• Continue / Cancel actions for paused requests
• Retry button to re-send a captured request

Summary Bar
