In-app debug & QA overlay for Flutter. Network inspector, mock engine, live logs, FPS monitor, feature flags, and automated QA reports. Dio & http adapters.

Changelog

0.3.2 - 2026-04-28

Fixed

• Upgraded connectivity_plus to ^7.1.0 (v7.1.x migrated web implementation to package:web instead of dart:html, restoring WASM compatibility on pub.dev).
• device_info_plus and package_info_plus upgraded to latest patch via dart pub upgrade (12.4.0 and 9.0.1 respectively).

---

0.3.1 - 2026-04-28

Fixed

• Widened dependency constraints to support latest major versions and restore full pub.dev score:
  • package_info_plus: >=9.0.0 <11.0.0 (was ^9.0.0, now supports v10.x)
  • device_info_plus: >=12.3.0 <14.0.0 (was ^12.3.0, now supports v13.x)
  • connectivity_plus: >=7.0.0 <8.0.0 (was ^7.0.0, explicit upper bound)
  • All APIs used (DeviceInfoPlugin, PackageInfo.fromPlatform, Connectivity.checkConnectivity) are stable and unchanged between these major versions.

0.3.0 - 2026-04-28

Added

• CLI Init Tool — dart run flutter_blackbox:init auto-detects your project's dependencies (Dio, http, Socket.IO, SharedPreferences) and prints the exact setup code you need.
  • --generate flag generates a lib/blackbox_adapters.dart file with only the adapters your project uses — zero unnecessary packages installed.
  • --help for full usage instructions.
• CLI-generated adapter architecture — concrete adapter implementations (DioBlackBoxAdapter, HttpBlackBoxAdapter, SocketIOBlackBoxAdapter, SharedPrefsStorageAdapter) are no longer bundled inside lib/. They are generated into the user's project by the CLI. This means:
  • flutter_blackbox has zero optional dependencies — 63 KB total package size.
  • Dio users don't get http, socket_io_client, or shared_preferences installed.
  • The generated lib/blackbox_adapters.dart is fully editable and customizable.
  • Same zero-setup pattern as build_runner, freezed, and injectable.
• Copy as cURL — one-tap button in Network panel copies any request as a valid curl command (with headers, body, method).
• Status Code Filtering — filter chips to show only 2xx, 4xx, 5xx, Pending, or Failed requests.
• Method Filtering — filter by HTTP method (GET, POST, PUT, DELETE, PATCH).
• Response Size Display — shows response body size (B/KB/MB) in each network tile and detail view.
• Request Timing Visualization — color-coded timing bars (green < 300ms, yellow < 1000ms, red > 1000ms) with speed indicator.
• Pretty JSON Viewer — collapsible, syntax-highlighted JSON tree with color-coded types. Auto-expands first level.
• Search Across All Panels — new "Search" tab that queries Network, Logs, Crashes, and Socket events simultaneously.
• Full Dartdoc Coverage — all public APIs, stores, and models now have comprehensive documentation for better IDE support and higher pub.dev scoring.
• Web Compatibility — removed dart:io dependencies from UI panels to ensure the package runs smoothly on Flutter Web.

Changed

• Full "devkit" → "BlackBox" rebrand — all file names, imports, internal references, and the overlay badge now use the BlackBox name consistently.
• Main barrel (flutter_blackbox.dart) exports only abstract interfaces (BlackBoxHttpAdapter, BlackBoxSocketAdapter, BlackBoxStorageAdapter). Concrete adapter implementations are generated into the user's project by the CLI.
• Moved dio, http, shared_preferences, socket_io_client from dependencies to dev_dependencies — users only install what they actually use.
• Overlay badge now shows "BlackBox" instead of "devkit".
• Internal Dio extras keys renamed from devkit_request_id/devkit_start_ms to blackbox_request_id/blackbox_start_ms.
• NetworkResponse model now includes optional responseSizeBytes field and formattedSize getter.
• Dio and HTTP adapters now capture response size automatically.
• Network panel detail view reorganized with timing summary card, collapsible JSON sections, and action buttons (cURL, Copy URL, Copy All).

Fixed

• Fixed duplicate property definitions in BlackBox singleton class.
• Fixed flaky broadcast stream tests in NetworkStore by accounting for event throttling.
• Added missing exports for JourneyEvent, FpsMonitor, and BlackBoxDeviceInfo to the main barrel file.

Performance

• NetworkPanel: Replaced two independent StreamBuilders on the same stream with a single StreamSubscription. Previously every network event triggered two separate rebuild cycles; now it triggers one.
• _NetworkTile: Cached the Uri.parse() result as late final _endpoint in initState/didUpdateWidget. URI parsing no longer runs on every build() call.
• _CollapsibleJsonSection: Replaced the _parsed computed getter with a late final field set in initState. jsonDecode now runs once per section lifecycle instead of on every rebuild.
• RebuildPanel: Converted to StatefulWidget + StreamSubscription. Removed the Stream.value(...) anti-pattern and the (context as Element).markNeedsBuild() framework hack.

Migration

• If you previously used import 'package:flutter_blackbox/flutter_blackbox.dart' and relied on Dio/http/Socket/Storage adapters being auto-exported, add the specific adapter import:

  // Before (v0.2.x) — everything from one import
  import 'package:flutter_blackbox/flutter_blackbox.dart';
  
  // After (v0.3.0) — add adapter imports you need
  import 'package:flutter_blackbox/flutter_blackbox.dart';
  import 'package:flutter_blackbox/adapters/dio.dart';         // if using Dio
  import 'package:flutter_blackbox/adapters/shared_prefs.dart'; // if using SharedPreferences
  

0.2.2 - 2026-04-06

Fixed

• Added CHANGELOG updates and minor version bumps for successful pub.dev publication.

0.2.1 - 2026-04-06

Added

• ignoredRebuildWidgets config in BlackBox.setup() to allow overriding and muting noisy custom 3rd-party widgets in the Rebuild tab.
• Smart Noise Filters hardcoded over 100+ native Flutter framework base widgets (Text, AutomaticKeepAlive, Container, etc) and 60fps animators (LinearProgressIndicator) from tracking to prevent noise.

Fixed

• Corrected regex string parsing for Flutter framework's raw rebuild log output (Building/Rebuilding) so Rebuild Tracking accurately measures widget rebuilds rather than staying at zero.
• Rebuild Tracker console spam fixed. Intercepted framework logs are now securely routed to the UI tab while completely muted from terminal output for cleaner logging.
• Fixed infinite rendering loops where BlackBoxOverlay and RebuildTrackerWidget recursively logged themselves in the Rebuild store.

0.2.0 - 2026-03-24

Added

• Storage Inspector — inspect, search, edit, delete key-value pairs from any storage backend.
  • Built-in SharedPrefsStorageAdapter.
  • Adapter pattern (BlackBoxStorageAdapter) supports GetStorage, Hive, FlutterSecureStorage, etc.
• Privacy & Sensitive Data Redaction — keys matching common patterns (password, token, secret, jwt, etc.) auto-redacted.
  • Global toggle: redactSensitiveData in BlackBox.setup() (default: true).
  • 25+ built-in sensitive patterns, customizable per adapter.
  • Sensitive values show as •••••••• — can't be copied or edited.
• Widget Rebuild Tracker — track widget rebuild counts for performance bottlenecks.
  • Auto mode: debugPrintRebuildDirtyWidgets hook — zero code changes.
  • Manual mode: RebuildTracker widget wrapper (zero-cost in release builds via kDebugMode).
• Socket.IO Adapter — auto-capture all incoming socket events via socket.onAny().
  • SocketIOBlackBoxAdapter(socket) — no changes to socket code.
• HttpBlackBoxAdapter — observe-only adapter that takes your existing http.Client.

Changed

• Observe-only philosophy — all adapters now hook into libraries' built-in extension points without replacing trusted code.
• BlackBoxHttpClient is now @Deprecated — replaced by HttpBlackBoxAdapter(client).

Removed

• Feature Flags panel and LocalFlagAdapter — replaced by Storage Inspector and Rebuild Tracker.

0.1.4 - 2026-03-19

Fixed

• Bumped dio lower bounds to ^5.4.0 in pubspec.yaml to ensure compatibility with DioException and restore pub.dev points.

0.1.3 - 2026-03-19

Changed

• Renamed all public classes from DevKit to BlackBox to fully align with the new package name.

0.1.1 - 2026-03-19

Changed

• Updated README and internal configuration to correctly reflect the flutter_blackbox package name.

Added

• Single-package release — Dio and http adapters bundled in core
• DevKitOverlay — tabbed debug panel above Navigator
• Network panel — request/response log with headers and body
• Mock engine — intercept any HTTP request with fake response
• Log panel — captures debugPrint() automatically
• Performance panel — live FPS graph and jank detection
• Feature flags panel — runtime toggle without restart
• Device panel — platform, screen, OS info
• QA Report — one-tap screenshot + logs + network bundle
• DioDevKitAdapter — Dio interceptor (included in core)
• DevKitHttpClient — http.Client drop-in (included in core)
