StreamMessageInput causing error "Could not find a Portal above this PortalTarget(debugName: null, portalCandidateLabels=[PortalLabel.main])"

Which packages are you using?

stream_chat_flutter

On what platforms did you experience the issue?

Android

What version are you using?

7.1.0 (flutter 3.22.0)

What happened?

The following PortalNotFoundError was thrown building _PortalTargetVisibilityBuilder(visible: false, closeDuration: null, builder: Closure: (BuildContext, bool) => Widget, dirty, state: _PortalTargetVisibilityBuilderState#6a473):
Error: Could not find a Portal above this PortalTarget(debugName: null, portalCandidateLabels=[PortalLabel.main]).

The relevant error-causing widget was:
    StreamMessageInput StreamMessageInput:file:///home/john/dev/WorkWith/lib/src/features/chat/presentation/channel_page/channel_page.dart:27:17

When the exception was thrown, this was the stack:
#0      _PortalTargetState.build.<anonymous closure> (package:flutter_portal/src/portal_target.dart:265:11)
portal_target.dart:265
#1      _PortalTargetVisibilityBuilderState.build (package:flutter_portal/src/portal_target.dart:449:26)
portal_target.dart:449
#2      StatefulElement.build (package:flutter/src/widgets/framework.dart:5599:27)
framework.dart:5599

Steps to reproduce

Here is my code (this code is exactly the same as the code in https://github.com/GetStream/stream-chat-flutter/issues/1923 but with the app_bar removed from channel_page.dart and StreamMessageInput added):

gorouter:

      GoRoute(
        path: '/home',
        name: AppRoute.home.name,
        builder: (context, state) {
          final tabName = state.uri.queryParameters['tab'];
          final tab =
              tabName == null ? TabsEnum.venues : getTabFromString(tabName);
          return StreamChat(
            client: streamChatClient,
            child: HomePage(
              tab: tab,
            ),
          );
        },
        routes: [
          GoRoute(
            path: 'chat',
            name: AppRoute.venueChat.name,
            builder: (context, state) {
              Channel channel = state.extra as Channel;
              return StreamChannel(
                channel: channel,
                child: const ChannelPage(),
              );
            },
          ),
        ],
      )

chat_tab.dart (as a tab in BottomNavigationBar):

import 'package:flutter/material.dart';

  @override

}

class _ChatTabState extends ConsumerState<ChatTab> {
  OwnUser? ownUser;

  Future<void> connectUser(Profile profile) async {
    if (ownUser != null) {
      return;
    }
    final user = User(
      id: ref.read(authRepositoryProvider).currentUserId,
      extraData: {
        'username': profile.username!,
        'image': profile.profilePhotoUrl,
      },
    );
    ownUser = await streamChatClient.connectUser(
      user,
      streamChatClient.devToken(profile.username!).rawValue,
    );
  }

  @override
  Widget build(BuildContext context) {
    final profile = ref
        .watch(profileTabControllerProvider
            .select((value) => value.profileGetStatus))
        .value;
    if (profile == null) {
      return const Center(child: CircularProgressIndicator());
    } else {
      return FutureBuilder(
        future: connectUser(profile),
        builder: (context, snapshot) {
          if (snapshot.connectionState == ConnectionState.waiting) {
            return const Center(child: CircularProgressIndicator());
          } else {
            return ChannelListPage(client: streamChatClient);
          }
        },
      );
    }
  }
}

channel_list.dart:

import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
import 'package:stream_chat_flutter/stream_chat_flutter.dart';
import 'package:workwith/src/logger.dart';
import 'package:workwith/src/routing/app_router.dart';

class ChannelListPage extends StatefulWidget {
  const ChannelListPage({
    super.key,
    required this.client,
  });

  final StreamChatClient client;

  @override
  State<ChannelListPage> createState() => _ChannelListPageState();
}

class _ChannelListPageState extends State<ChannelListPage> {
  late final _controller = StreamChannelListController(
    client: widget.client,
    filter: Filter.in_(
      'members',
      [StreamChat.of(context).currentUser!.id],
    ),
    channelStateSort: const [SortOption('last_message_at')],
  );

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) => Scaffold(
        body: RefreshIndicator(
          onRefresh: _controller.refresh,
          child: StreamChannelListView(
            controller: _controller,
            onChannelTap: (channel) {
              logger().w('Channel tapped: ${channel.cid}');
              context.pushNamed(AppRoute.venueChat.name, extra: channel);
            },
          ),
        ),
      );
}

channel_page.dart:

import 'package:flutter/material.dart';
import 'package:stream_chat_flutter/stream_chat_flutter.dart';

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: <Widget>[
          Expanded(
            child: StreamMessageListView(
              messageBuilder:
                  (context, details, messageList, defaultMessageWidget) {
                return defaultMessageWidget.copyWith(
                  showThreadReplyIndicator: false,
                  showUserAvatar: DisplayWidget.show,
                  reverse: true,
                );
              },
            ),
          ),
          const StreamMessageInput(),
        ],
      ),
    );
  }
}

Also in main.dart I wrap the MaterialApp.router with StreamChatTheme (following the last comment here: https://github.com/GetStream/stream-chat-flutter/issues/1892)
