Environments

Learn how to configure your SDK to tell Sentry about your environments.

Environments tell you where an error occurred, whether that's in your production system, your staging server, or elsewhere.

Sentry automatically creates an environment when it receives an event with the environment parameter set.

Environments are case-sensitive. The environment name can't contain newlines, spaces or forward slashes, can't be the string "None", or exceed 64 characters. You can't delete environments, but you can hide them.

Copied
import 'package:flutter/widgets.dart';
import 'package:sentry_flutter/sentry_flutter.dart';

Future<void> main() async {
  await SentryFlutter.init(
    (options) => options.environment = 'staging',
    appRunner: () => runApp(MyApp()),
  );

  // or define SENTRY_ENVIRONMENT via Dart environment variable (--dart-define)
}

Environments help you better filter issues, releases, and user feedback in the Issue Details page of sentry.io, which you learn more about in our documentation that covers using environments.
