Sentry.close must be called in an isolate otherwise it won't shut down

[buenaflor]

Description

"I'm calling Sentry.init in my isolate (the non-flutter variant) and found my isolate wouldn't shutdown until I added Sentry.close as the last line in the isolate."

Let's verify this first and then document it

I tested with the following code.

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

Future<void> main(List<String> arguments) async {
  print('before sentry isolate');
  await Isolate.run(_sentryIsolate);
  print('after sentry isolate');
}

Future<void> _sentryIsolate() async {
  print('sentry isolate start');
  await Sentry.init((options) {
    options.dsn = 'https://[email protected]/5428562';
  });
  // await Sentry.close();
  print('sentry isolate end');
}

It makes no difference if we close sentry or not, the output is the same in both cases.

before sentry isolate
sentry isolate start
sentry isolate end
after sentry isolate

@buenaflor Can we reach the user somehow to get a sample where this is occurring?
