Connect your Flutter project to GlitchTip

Install the sentry Flutter SDK:

flutter pub add sentry_flutter

Initialize the SDK in lib/main.dart:

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

void main() {
  SentryFlutter.init(
    (options) => options
      ..dsn = 'YOUR_DSN'
      ..tracesSampleRate = 0.01 // 1% of transactions
      ..enableAutoSessionTracking = false, // GlitchTip does not support sessions
    appRunner: () => runApp(MyApp()),
  );
}

Verify your setup:

try {
  throw Exception('Test GlitchTip error!');
} catch (exception, stackTrace) {
  Sentry.captureException(exception, stackTrace: stackTrace);
}

Configuration

You can also set DSN and other options via environment variables with --dart-define:

flutter run --dart-define=SENTRY_DSN='YOUR_DSN'

Debug Symbols

Upload Dart symbol maps for readable stack traces using the GlitchTip CLI:

glitchtip-cli dart-symbol-map upload ./build/app.android-arm64.symbols ./build/app.android-arm64 --org my-org --project my-project

Tips

• Flutter supports web, mobile, and desktop. The SDK captures errors on all platforms.
• Set tracesSampleRate to a low value in production to save disk space.
