HTTP Integration

Learn more about the Sentry HTTP integration for the Dart SDK.

The SentryHttpClient can also catch exceptions that may occur during requests — for example SocketException.

Copied
import 'package:sentry/sentry.dart';

var client = SentryHttpClient();
try {
var uriResponse = await client.post('https://example.com/whatsit/create',
     body: {'name': 'doodle', 'color': 'blue'});
 print(await client.get(uriResponse.bodyFields['uri']));
} finally {
 client.close();
}

This is an opt-out feature. The following example shows how to disable it:

Copied
import 'package:sentry/sentry.dart';

Future<void> main() async {
  await Sentry.init(
    (options) {
      options.dsn = 'https://examplePublicKey@o0.ingest.sentry.io/0';
      options.captureFailedRequests = false;
    },
    appRunner: initApp, // Init your App.
  );
}

Furthermore you can track HTTP requests that you consider bad. In the following example, exceptions are captured for each request with a status code within the range of 400 to 404, and also for 500.

Copied
import 'package:sentry/sentry.dart';

var client = SentryHttpClient(
  failedRequestStatusCodes: [
    SentryStatusCode.range(400, 404),
    SentryStatusCode(500),
  ],
);

try {
var uriResponse = await client.post('https://example.com/whatsit/create',
     body: {'name': 'doodle', 'color': 'blue'});
 print(await client.get(uriResponse.bodyFields['uri']));
} finally {
 client.close();
}

Capturing transactions requires that you first set up tracing if you haven't already.

The SentryHttpClient starts a span out of the active span bound to the scope for each HTTP Request.

Copied
import 'package:sentry/sentry.dart';

final transaction = Sentry.startTransaction(
  'webrequest',
  'request',
  bindToScope: true,
);

var client = SentryHttpClient();
try {
var uriResponse = await client.post('https://example.com/whatsit/create',
     body: {'name': 'doodle', 'color': 'blue'});
 print(await client.get(uriResponse.bodyFields['uri']));
} finally {
 client.close();
}

await transaction.finish(status: SpanStatus.ok());
