I have the following issue:

Every time I Hot Restart my app, my app crashes

Steps to reproduce:

• Create project
• import Sentry
• init Sentry
• hot restart app

Click to Expand

await SentryFlutter.init(
    (options) {
      options.dsn =
         <MY SENTRY DSN>
    },
    appRunner: () => runZonedGuarded(() {
      runApp(const MyApp());
    }, flogError),
  );

Actual result:

Restarted application in 1,187ms.

This is an issue with Flutter, not Sentry

@mrgnhnt96 pay attention to your init. block https://docs.sentry.io/platforms/flutter/#configure
you don't need a runZonedGuarded
