Cannot add new events while doing an addStream in tests

[xVemu]

Describe the bug
If I try to launch this test it throws an exception. I discovered if I switch to normal stream instead of broadcast stream, everything works fine.
If I remove .broadcast from here it works as it should:

flutter_hooks/packages/flutter_hooks/lib/src/async.dart

Line 307 in 319679b

late final _controller = StreamController<T>.broadcast(

To Reproduce

Code sample

import 'package:flutter/material.dart';
import 'package:flutter_hooks/flutter_hooks.dart';
import 'package:flutter_test/flutter_test.dart';

void main() {
  testWidgets("cooldown retry", (tester) async {
    await tester.pumpWidget(MyApp());
    await tester.tap(find.text("none"));
    await tester.pumpAndSettle();
    expect(find.textContaining("10"), findsOneWidget);
    await tester.pumpAndSettle(Duration(seconds: 10));
    expect(find.text("none"), findsOneWidget);
  });
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        body: Center(
          child: _SendSMS(),
        ),
      ),
    );
  }
}

class _SendSMS extends HookWidget {
  // ignore: unused_element
  const _SendSMS({super.key});

  @override
  Widget build(BuildContext context) {
    final streamController = useStreamController<int>();
    final cooldown = useStream(streamController.stream, initialData: 0);

    return TextButton(
      onPressed: () {
        streamController.add(10);
        streamController.addStream(
          Stream.periodic(
            Duration(seconds: 1),
            (i) => 10 - i - 1,
          ).take(10),
        );
      },
      child: Text((cooldown.data ?? 0) > 0 ? cooldown.data.toString() : "none"),
    );
  }
}

Expected behavior
Test should pass without errors.

[rrousselGit]

useStreamController creates a broadcast stream. It's part of its specs. That's not a bug but a feature.
Now, the issue is elsewhere. It appears that your addStream never complete.

So when the widget is unmounted, your addStream is still pending ; which causes the exception.
I'm not sure why your addStream fails, but if you change it to:

        await Future<void>.delayed(const Duration(seconds: 10));
        await streamController
            .addStream(Stream.fromIterable([9, 8, 7, 6, 5, 4, 3, 2, 1, 0])

The test passes.

[xVemu]

Yeah, but I need value every second, so it behaves more like a countdown

[rrousselGit]

My guess is that this is a Dart bug. I don't see why your take(10) wouldn't cause addStream to stop once the last event is received on broadcast controllers.

[xVemu]

Yep, it's the same when using StatefulWidget. Thanks for help
