vibebug_flutter 0.4.7

Crash reporting and visual bug capture for Flutter apps — reports issues to Vibe Bug Tracker with screenshots, widget selectors, and an offline queue.

vibebug_flutter

Crash reporting plus Chrome-extension-style visual bug capture for Flutter apps — sends issues to Vibe Bug Tracker with screenshots, widget selectors, and Flutter-specific AI markdown.

Testers in your app can capture a widget, crop and highlight the region, add screenshots, and send a fully-described issue straight to your tracker board — no Chrome extension required.

Get started in two commands

flutter pub add vibebug_flutter
dart run vibebug_flutter:configure

That's it — run your app. No manual code to write: configure finds and rewrites main.dart and your MaterialApp/CupertinoApp/GetMaterialApp itself, whatever your existing setup looks like (localization, theming, screen-size init — it wraps what's already there instead of replacing it). It always shows you the diff and asks before writing anything. See Installation below for details, flags, and what to do in the rare case it can't rewrite something safely.

Features

• Zero-config setup — one command wires everything into your app, no manual code required
• Built-in sign-in + project picker — your app runs normally from launch; the first time a tester taps the floating Report button, they see a login screen, then a project dropdown, and every report after that tracks against it automatically
• Automatic crash reporting — uncaught exceptions, FlutterError.onError, and platform errors are reported with stack traces
• Offline queue — reports are queued and retried when connectivity returns, with de-duplication
• Draggable Report button — testers can move the bubble anywhere on screen
• Widget picker + capture region editor — tap a widget to capture it, then crop/adjust the region and draw highlight marks
• Multi-screenshot issues — up to 8 captures per issue, like the Chrome extension
• Flutter-specific AI markdown — issue descriptions include widget selectors, route, and Flutter fix guidance
• Caught-exception API — report handled errors from anywhere in your code

Requirements

• Flutter >=3.16.0
• Dart SDK >=3.2.0 <4.0.0
• A Vibe Bug Tracker account, and a tester / owner / admin account with access to a project

Installation

flutter pub add vibebug_flutter

Then run the setup wizard:

dart run vibebug_flutter:configure

The configure command:

1. Rewrites main.dart so runApp() runs inside VibeBug.runGuarded(), with VibeBug.initialize() awaited just before it.
2. Finds your app root widget — MaterialApp, MaterialApp.router, CupertinoApp, or GetX's GetMaterialApp — and wires VibeBugScope into its builder:. If you already have a builder: (localization, screen-size init, theming, anything), it wraps whatever it already returns instead of replacing it, so your existing setup keeps working.
3. Generates lib/vibebug_config.dart with your backend base URL (no credentials — sign-in happens at runtime).

It always shows a diff and asks for confirmation before writing anything. Useful flags:

Flag	Purpose
--yes	Skip the confirmation prompt
--base-url <url>	Point at a self-hosted backend instead of the default https://vibebugtracker.com

It takes a .bak backup of every file it touches. Comments and string contents (e.g. 'https://...' URLs) are correctly ignored while scanning — leftover commented-out code (an old main(), an old MaterialApp from a previous refactor) is never mistaken for a second real one. If your main.dart/app root still don't match one of the shapes it knows how to rewrite safely, it leaves a // TODO(vibebug): ... comment explaining exactly what to do manually and why — see Troubleshooting.

That's it — run your app. It launches straight into your normal UI, exactly as before — nothing is blocked. The first time a tester taps the floating Report button, they see a sign-in screen (tester/owner/admin email + password), then a project picker; back out of either and nothing happens. Once a project is selected, every report from that device tracks against it until the user signs out (VibeBug.signOut()), and tapping Report goes straight into capture mode.

If you'd rather block the whole app behind sign-in until it's ready — appropriate for a dedicated tester app whose only purpose is reporting — pass VibeBugOptions(blockAppUntilReady: true). See Gate behavior below.

Example app

A complete runnable demo app lives in example/ — clone the repo and run it to test every SDK feature against your own Vibe Bug Tracker account:

git clone https://github.com/adnanpk44/vbt.git
cd vbt/example
flutter pub get
flutter run

It exercises crash reporting, caught exceptions, the draggable capture bubble, widget picker, and the offline queue.

└──────────────────────────────────────────────────────────────┘

Every report (crash, caught exception, or visual capture) goes through the same pipeline: authenticate → resolve target project/board/developer → enqueue → send immediately (or queue for offline retry).

Manual / advanced setup

Skip configure and wire things up yourself if you want full control, or if you're integrating into a headless/CI/kiosk build. Supplying email/password/token to VibeBugOptions (or setting enableAuthGate: false) bypasses the built-in sign-in/picker screens entirely — this is the path used by this repo's own flutter-vibebug-demo app.

dependencies:
  vibebug_flutter:
    path: ../packages/vibebug_flutter

Initialize and wrap with the same zone + MaterialApp builder:

import 'package:flutter/material.dart';
import 'package:vibebug_flutter/vibebug_flutter.dart';

void main() {
  // ensureInitialized and runApp must run in the same zone.
  VibeBug.runGuarded(() {
    WidgetsFlutterBinding.ensureInitialized();
    runApp(const MyApp());
  });
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  static final _navKey = GlobalKey<NavigatorState>();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorKey: _navKey,
      // Keep VibeBugScope under MaterialApp so Directionality/Theme exist.
      builder: (context, child) => VibeBugScope(
        navigatorKey: _navKey,
        child: child ?? const SizedBox.shrink(),
      ),
      home: const HomePage(),
    );
  }
}

await VibeBug.initialize(VibeBugOptions(
  onIssueSent: (issueId) => debugPrint('Reported $issueId'),
));

Call initialize before or after runApp (e.g. from your root widget after setup). If you want the built-in sign-in/picker gate (rather than supplying email/password/token yourself) and are wiring things up by hand instead of via configure, await initialize() before runApp() — otherwise your app's first frame can flash before the gate takes over. The generated configure output always does this for you.

Visual bug reporting

Put VibeBugScope in MaterialApp.builder (not above MaterialApp). When using MaterialApp.router, pass the router navigator key:

MaterialApp.router(
  routerConfig: goRouter,
  builder: (context, child) => VibeBugScope(
    navigatorKey: goRouter.routerDelegate.navigatorKey,
    child: child ?? const SizedBox.shrink(),
  ),
)

1. Drag the bubble to reposition it (position is remembered)
2. Tap the bubble — the first time, this is where sign-in and project selection happen (see Gate behavior); after that it goes straight to step 3
3. Tap a widget to capture it
4. Crop / highlight in the full-screen editor, add a per-capture note, then Save
5. Navigate to other screens freely, tap Report again to add more (up to 8)
6. Tap the badge on the bubble to review, choose the board/developer/priority, then Send

Long-press the bubble to clear draft captures.

Gate behavior

VibeBugOptions.blockAppUntilReady controls when the built-in sign-in/project-picker flow appears, for apps using the gate (i.e. not supplying email/password/token directly):

	blockAppUntilReady: false (default)	blockAppUntilReady: true
On launch	Your app shows immediately, unchanged	Blocked behind sign-in/picker until both are done
Sign-in/picker appear	The first time the tester taps Report	Before your app is shown at all
Best for	Embedding into an existing app with its own regular users (most apps — this is the default for exactly that reason)	A dedicated tester app whose only purpose is reporting

Regular users of your app who never tap Report never see a VibeBug screen at all under the default setting — nothing about your app's normal UI changes.

Options

VibeBugOptions fields:

Field	Default	Purpose
baseUrl	https://vibebugtracker.com	Backend base URL (self-hosting)
token	null	API token (bypasses sign-in)
email / password	null	Direct credentials (bypasses sign-in)
projectId / boardId / assignedTo	null	Default target project/board/developer
autoReportCrashes	true	Report uncaught exceptions automatically
reportInBackground	true	Send immediately; false = queue only
defaultPriority	high	Priority for auto-reported crashes
dedupeWindow	5 min	Suppress duplicate reports within this window
screenshotProvider	null	Future<String?> Function() for extra screenshots
onIssueSent	null	Callback with the created issue id
onError	null	Callback for send/queue errors
enableAuthGate	null	Auto-detect: on when no creds supplied, off otherwise
autoSelectSoleProject	false	Skip picker when sign-in resolves to exactly one project
blockAppUntilReady	false	true blocks the whole app behind the gate on launch instead of gating the Report button — see Gate behavior

Widgets

Widget	Purpose
VibeBugScope	Draggable capture bubble + gate; wrap MaterialApp.builder
VibeBugReportButton	Legacy text-only report button

Models

• VibeBugScreenshotShot — one visual capture (selected + full screenshots, selector, semantics)
• VibeBugProject / VibeBugBoard / VibeBugDeveloper — target selection metadata

Caught exceptions

try {
  await riskyOperation();
} catch (e, stack) {
  await VibeBug.reportException(e, stack, description: 'Checkout failed');
}

Programmatic multi-capture submit

await VibeBug.reportIssueWithCaptures(
  summary: 'Checkout CTA overlaps total on small screens',
  captures: shots, // List<VibeBugScreenshotShot>
);

Troubleshooting configure

configure refuses to guess when your main.dart or MaterialApp don't match a shape it can rewrite safely. Each reason it can print, and the manual fix:

Reason	Manual fix
Multiple/zero main() or runApp()	Wrap your existing runApp(...) call in VibeBug.runGuarded(() async { ...; await VibeBug.initialize(VibeBugOptions(baseUrl: ...)); runApp(...); }); yourself.
runApp() nested inside another callback, or has trailing code (e.g. .then(...))	Same as above — move the VibeBug.initialize() call to just before wherever runApp() actually runs.
VibeBug.runGuarded() present but no VibeBug.initialize() inside it	Add await VibeBug.initialize(VibeBugOptions(baseUrl: ...)); inside the runGuarded closure, before runApp().
Multiple/zero app root widgets (MaterialApp, CupertinoApp, GetMaterialApp) found	Wrap your app's builder: yourself, per the Manual / advanced setup example above.
builder:'s body has a shape this tool doesn't recognize (multiple return statements, an unusual parameter list, etc.)	Wrap whatever your builder: currently returns with VibeBugScope(child: ...) yourself.

Still stuck, or configure bailed for a reason not listed here? Open an issue with the exact message it printed — that's a gap in the tool, not something you're doing wrong, and it helps fix it for the next person too.

Notes

• Widget inspection works best in debug/profile builds where Flutter exposes widget creators
• Screenshot capture requires VibeBugScope (uses an internal RepaintBoundary)
• Requires a tester, project admin, or workspace owner/admin account with access to the target project — the SDK always reports as a tester (X-VIT-Acting-Role: tester), so owner/admin accounts with no dedicated tester seat are included automatically
• Reports use the same /api/extension/issues endpoint with a screenshots[] payload as the Chrome extension
