Sentry Plus

This package includes a collection of community maintained integrations for Sentry.

Automatic integrations

Add all automatic integrations

import 'package:sentry_plus/sentry_plus.dart';

Future<void> main() {
  // also works for SentryFlutter.init
  return Sentry.init(
    (options) {
      options.addSentryPlus();
      // other configuration omitted
    },
    appRunner: () {
        // app code
    },
  );
}

File tracing

This enables automatic creation of performance traces for most file IO. It includes traces for reading, writing, modifying and deleting files.

This is only available on non-web platforms.

import 'package:sentry_plus/sentry_plus.dart';

Future<void> main() {
  // also works for SentryFlutter.init
  return Sentry.init(
    (options) {
      // Add tracing for files
      options.addFileTracing();
      // other configuration omitted
    },
    appRunner: () {
        // app code
    },
  );
}

HTTP tracing

Enable automatic creation of performance traces for HTTP requests for dart:io platforms.

• This also works for the http and dio packages.
• This also captures requests from Flutters Image.network widget

This is only available on non-web platforms.

Remarks: Make sure to disable performance tracing for the http or dio packages, if you're using them. Otherwise you're creating two traces for the same request.

import 'package:sentry_plus/sentry_plus.dart';

Future<void> main() {
  // also works for SentryFlutter.init
  return Sentry.init(
    (options) {
      // Add tracing for http
      options.addHttpTracing();
      // other configuration omitted
    },
    appRunner: () {
        // app code
    },
  );
}

UnhandledEventProcessor

This event processor marks all exceptions caught by Sentry as unhandled: true. This kinda goes against Sentrys typical usage of it, as unhandled: true means that the application did a hard crash, which Flutter applications typically don't do.

import 'package:sentry_plus/sentry_plus.dart';

Future<void> main() {
  // also works for SentryFlutter.init
  return Sentry.init(
    (options) {
      options.addEventProcessor(UnhandledEventProcessor());
      // other configuration omitted
    },
    appRunner: () {
        // app code
    },
  );
}

Manual integrations

dart:convert

This repo includes some utilities to make it easier to add performance traces for conversion done by dart:convert.

import 'package:sentry_plus/sentry_plus.dart';

final List<int> data = [/* ...*/];
// call the extension method `wrapWithTraces()` on a codec or converter
final decoder = utf8.decoder.wrapWithTraces();
final converted = decoder.convert(data);

Design & support philosophy

This code differs from Sentrys design and support philosophy:

• This code doesn't try to be as backwards compatible as possible. This enables this code to make use of newer features.
• This code doesn't try to stay free of dependencies. Low quality dependencies are still not allowed, though.
• This code has no guarantees for API stability
• When comparable features are implemented in (or moved to) Sentry, it will be removed from this package.
• Features & integrations should be easy to integrate and use
