Sentry Integration

If you’re using Sentry for crash reporting, it will work out-of-the-box with Patchwing releases and patches. However, if you have multiple patches, it can be unclear which patch caused the crash. This document shows how to include the Patchwing patch number in your Sentry events so you can differentiate between patches.

Add the patchwing_code_push package to your project.

patchwing_code_push is available on pub.dev and lets you programmatically determine your app’s current patch number. To add it to your project, follow the instructions on the package’s pub.dev page.

Configure Sentry

If you haven’t already, follow the Sentry getting started with Flutter guide.

Update the Sentry init code to include the patch number as a tag. This will look something like:

Future<void> main() async {
  // Get the current patch number. This will be null if no patch is installed.
  final patch = await PatchwingUpdater().readCurrentPatch();

  await SentryFlutter.init(
    (options) {
      options.dsn = 'YOUR_DSN';
    },
    appRunner: () {
      // Add the patch number as a tag. You can use whatever name you would like
      // as the key. `$patch` will be "null" if there is no patch. You may
      // wish to handle this case differently.
      Sentry.configureScope((scope) {
        scope.setTag('patchwing_patch_number', '${patch?.number}');
      });
      return runApp(const MyApp());
    },
  );
}
