WARNING: experimental code

Use this library in your Dart programs (Flutter, command-line and (TBD) AngularDart) to report errors thrown by your program to error tracking service.


Sign up for a account and get a DSN at

Add sentry dependency to your pubspec.yaml:

  sentry: any

In your Dart code, import package:sentry/sentry.dart and create a SentryClient using the DSN issued by

import 'package:sentry/sentry.dart';

final SentryClient sentry = new SentryClient(dsn: YOUR_DSN);

In an exception handler, call captureException():

main() async {
  try {
  } catch(error, stackTrace) {
    await sentry.captureException(
      exception: error,
      stackTrace: stackTrace,

Tips for catching errors

  • use a try/catch block
  • create a Zone with an error handler, e.g. using runZoned
  • in Flutter, use FlutterError.onError
  • use Isolate.current.addErrorListener to capture uncaught errors in the root zone

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Maintain an example.

    Create a short demo in the example/ directory to show how to use this package. Common file name patterns include: main.dart, example.dart or you could also use sentry.dart.
