Error monitoring SDK for Flutter — by Pionne.

Auto-captures Flutter framework errors and unhandled async/zone errors, ships rich runtime context (Dart version, OS, locale, debug/release mode). Single dependency: http. Wire-format compatible with @pionne/react-native, @pionne/web, @pionne/node.

🎫 Get your token

Pionne is mobile-first: you sign up, create projects, and watch your error feed from the Pionne mobile app, not a web dashboard.

1. Download the app:
   • 🍎 App Store (coming soon)
   • 🤖 Google Play (coming soon)
2. Create your account (30 days free, no card required)
3. + New project → pick Flutter → copy the token displayed (pio_live_…)
4. Paste it into Pionne.init(PionneOptions(token: ...)) below

⚠️ The token is only shown once at project creation — load it from --dart-define=PIONNE_TOKEN=… at build time, never hard-code it in source.

Install

dependencies:
  pionne_flutter: ^0.1.0

flutter pub get

Usage

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

void main() {
  Pionne.init(PionneOptions(
    token: 'pio_live_xxx',
    release: '1.0.0',
  ));

  // Wrap the app to also catch zone errors:
  Pionne.runZonedGuarded(() => runApp(const MyApp()));
}

That's it. Flutter framework errors and unhandled async errors are now reported.

Manual capture

try {
  await processOrder();
} catch (e, stack) {
  Pionne.captureException(e,
    stackTrace: stack,
    tags: {'feature': 'checkout'},
  );
  rethrow;
}

Pionne.captureMessage('user reached empty state', level: Level.info);

User identity, tags, opt-out

Pionne.setUser('u_42');
Pionne.setTags({'tier': 'pro'});
Pionne.setEnabled(false);

Geography (opt-in)

Approximate user location (city, region, country) attached to every event, just like Sentry. Off by default for privacy — flip sendGeography to enable:

Pionne.init(PionneOptions(
  token: 'pio_live_xxx',
  sendGeography: true,
));

Resolved once at startup via a free IP→geo lookup (https://ipapi.co/json/ by default), with a 4 s timeout. If the lookup fails the SDK silently keeps shipping events without geo. Override the endpoint via geographyEndpoint if you have your own.

Release Health

Pionne.init(PionneOptions(
  token: 'pio_live_xxx',
  releaseHealth: true, // default
));

Ouvre une session au boot, la flippe à crashed/errored si une exception fatale est captée. Le dashboard dérive le crash-free user rate par release. Désactivable.

Rate limit client (anti-runaway)

Pionne.init(PionneOptions(
  token: 'pio_live_xxx',
  maxEventsPerSecond: 10, // default
));

Token-bucket process-wide. Au-delà, les events sont droppés silencieusement. Protège contre une boucle d'erreur dans un Timer.periodic qui throw. Mettre à 0 désactive (déconseillé).

Rate limit serveur

Indépendamment de maxEventsPerSecond, l'API Pionne cap 600 req/min/token (= 10/sec) sur tous les endpoints publics (/ingest, /sessions, /feedback). Au-delà → HTTP 429 avec un header Retry-After. Le SDK fait silencieusement échouer (try/catch interne). Empêche un token leaké de drainer ton infra ou ton quota mensuel. Voir doc rate limits.
