Basically i want to do something like search box on the top of my ChannelListView.
I know that we can filter using members but currently it only allows filter using user.id not user name or channel name

I got an error like this after i add dependency stream_chat_flutter: ^0.1.11
when i try to run it on iOS, my app suddenly got force close

Channel Header provides a way to customize the display and action of the back button but nothing to do an action for when the header is tapped.

Propposed solution:

• Add an action (similar to the onBackPressed) for when the ChannelName Widget is tapped.

This is useful for showing a custom page with the channel information (image, members, custom actions for notifications, adding more people to the chat, etc)

On the same note, a custom action on tapping the channel's image ChannelImage can be added.

i got this error message when using the alpha version

the chat functionality still working fine though

is there a way to customize ChannelHeader & MessageInput ?
for example change the logic to upload attachment to my own CDN, or use my own AppBar as ChannelHeader

When creating a new channel (for example, from the CLI), that does not have any messages in the channel, will cause ChannelListView widget to throw an error as there are no checks to see if the channel message list is empty.

The method 'toLocal' was called on null.
Receiver: null
Tried calling: toLocal()

The relevant error-causing widget was
    ChannelListView 
lib/main.dart:147
When the exception was thrown, this was the stack
#0      Object.noSuchMethod  (dart:core-patch/object_patch.dart:53:5)
#1      ChannelPreview._buildDate.<anonymous closure> 
package:stream_chat_flutter/src/channel_preview.dart:71
#2      StreamBuilder.build

package:flutter/…/widgets/async.dart:125
#4      StatefulElement.build 
package:flutter/…/widgets/framework.dart:4334
... 

There needs to some validation to make sure there are messages, before calling:

final lastMessageAt = snapshot.data.toLocal(); in "channel_preview.dart"

Widget _buildDate(BuildContext context) {
    return StreamBuilder<DateTime>(
      stream: channel.lastMessageAtStream,
      initialData: channel.lastMessageAt,
      builder: (context, snapshot) {
        final lastMessageAt = snapshot.data.toLocal();

        String stringDate;
        final now = DateTime.now();

        if (now.year != lastMessageAt.year ||
            now.month != lastMessageAt.month ||
            now.day != lastMessageAt.day) {
          stringDate = Jiffy(lastMessageAt.toLocal()).format('dd/MM/yyyy');
        } else {
          stringDate = Jiffy(lastMessageAt.toLocal()).format('HH:mm');
        }

        return Text(
          stringDate,
          style: StreamChatTheme.of(context).channelPreviewTheme.lastMessageAt,
        );
      },
    );
  }

i got this error message after implementing notification for my ios app, but the notification and chat functionality is working fine though

flutter: (2020-06-18 13:54:58.181137) 🚨 📡 Error during resync ApiError{body: Not Found, jsonData: null, status: 404, code: null}

I am testing your Flutter Chat SDK "0.2.1-alpha+3" with offline capability which is critical for our use case. Reported a problem via GitHub page 2 days back and thanks for fixing the database exception quickly.

After trying the latest Alpha build one problem I have observed is incoming messages are not coming after a re-connection due to network change or connection reset, though outgoing messages are going after re-connection. If user manually refreshes the chats landing page by pull refresh, messages are being pulled from server by calling an API but until that is done manually messages are noting getting delivered to the client. What can we do to ensure message sent receive happens automatically as soon as server connection is established.

Also please let us know if we should report this kind of issues via support or should we post it on GitHub page, we will follow as you advise.

Steps to reproduce issue:

1. Login in app
2. Send messages
3. Turn off internet connectivity
4. Sent some messages from other device
5. Again turn on internet connectivity
   Then that message is not received until we manually refresh the lending page or re-open app.

The api provides a way to send a custom payload through attachments and we can have a MessageBuilder that easily handles this scenario:

MessageListView(
  showVideoFullScreen: true,
  messageBuilder:_buildCustomMessage,
  showOtherMessageUsername: true,
  threadBuilder: (_, parentMessage) {
  return ThreadPage(
  parent: parentMessage,
  );
  },
),

and in _buildCustom Message logic for it can be done, however, it would basically requiere to re-write the MessageWidget with all its features + a small set of builders for the attachments.

Proposed Solution:

Add a list of AttachmentBuilders to the MessageListView that can be passed down to the MessageWidget and it can be used during _buildBubble

i got this warning message after disconnect from current client using client.disconnect(); and then set a new user using _client.setUser()

i dont know if i should be concerned or it just a false warning message

ex: Today, Yesterday, etc

What would be the best approach to have a side by side chat experience? I'm developing an app that supports tablet screen width. Looks like route navigation is already built-in so clicking on a channel would just push open the provided channelWidget?

Videos, whether uploaded or taken, show as stretched horizontally. See attached photos:

1. Screenshot from the original video taken on the iPhone 11 Max
   

2. How it looks in chat when played fullscreen
   

3. How it looks in chat inline
   

so, my message contains link and its color is always blue, is there a way to customize that link color?

gz#4536

How can I listen on the tap event of the message list avatar, such as click avatar to jump to user profile page? I couldn't find the param.

gz#4659

We are testing the Alpha+4 build and enabled Presence and Last Seen in the application. Before doing that we figured out how to check information from server by logging and quering it at API level.

What we observed is a inconsistent behavior from client on updating the status to server.

Even if we kill the application of user A it keeps showing online on user B, and this goes on even if we restart application of User B it keeps showing user A as online. Secondly if User A is showing "5 mins back" to User B and we stop application on user B and then start application on user A send a message and stop it, it should show "few seconds or 1 min" back on user B but it shows "6 mins" back which means user A did not update the information to server correctly, to reverify it we checked on server and it was not updated. Same behavior if we interchange User A and User B or user C and user D, etc, so it is reproducible.

But at the same it is not happening every time, sometimes it is updating the information on server and we are able to see correctly.
Also we have checked with API response, user last active not showing correctly sometimes.

Message Input grows with message content but doesn't stop, reaching an overflow.

Image attached for reference:

If there's no one working on this one, I can PR a fix today.

I've tried various things from this repository to try and get it working with no success https://github.com/rodydavis/moor_shared

Could you please provide a sample web target for this project to get started with this on Web?

I think we need to add read & delivered indicator for one-to-one conversations, currently it only shows SendingIndicator

Once you tap the text input field, the keyboard cannot be hidden without sending a message. This is a problem if you have bottom bar navigation and have showBackButton: false.

Hey!! I want to change the bg color of my StreamChat widget but even after changing the streamChatThemeData nothing works.

This is what my code looks like

Chat.StreamChat(
                  client: controller.client,
                  streamChatThemeData: Chat.StreamChatThemeData.fromTheme(appTheme),
                  child: Chat.StreamChannel(
                    channel: controller.channel,
                    child: ChannelPage(),
                  ),
                ),

I have followed the guide create the ChannelListPage and ChannelPage, and it works fine for me. But now I want to open a one to one conversation, but when I navigate to StreamChannel, it keeps on loading, and I don't know how to make it work. Help me, please.

This is my code.

class ChannelListPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        centerTitle: true,
        title: Text(
          'Messages',
          style: TextStyle(fontWeight: FontWeight.bold, fontSize: 15),
        ),
      ),
      bottomNavigationBar: CustomButtomBar(
        index: 2,
      ),
      body: ChannelsBloc(
        child: ChannelListView(
          filter: {
            'members': {
              '\$in': [StreamChat.of(context).user.id],
            }
          },
          sort: [SortOption('last_message_at')],
          pagination: PaginationParams(
            limit: 20,
          ),
          channelWidget: ChannelPage(),
        ),
      ),
    );
  }
}

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: ChannelHeader(),
      body: Column(
        children: <Widget>[
          Expanded(
            child: MessageListView(
              threadBuilder: (_, parentMessage) {
                return ThreadPage(
                  parent: parentMessage,
                );
              },
            ),
          ),
          MessageInput(),
        ],
      ),
    );
  }
}

class ThreadPage extends StatelessWidget {
  final Message parent;

  ThreadPage({
    Key key,
    this.parent,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: ThreadHeader(
        parent: parent,
      ),
      body: Column(
        children: <Widget>[
          Expanded(
            child: MessageListView(
              parentMessage: parent,
            ),
          ),
          MessageInput(
            parentMessage: parent,
          ),
        ],
      ),
    );
  }
}

and these is how to navigate to channel page. These code is in other place to jump to ChannelPage.

                                onTap: () async {
                                  var conversation = Chat()
                                      .client
                                      .channel("messaging", extraData: {
                                    "members": [
                                      user.id.toString(),
                                      ClientChannelManager.getUser()
                                          .id
                                          .toString()
                                    ]
                                  });
                                  Navigator.push(context, MaterialPageRoute(
                                    builder: (context) {
                                      return StreamChannel(
                                        child: ChannelPage(),
                                        channel: conversation,
                                      );
                                      //   return MessagePage(
                                      //   userId: user.id,
                                      // );
                                    },
                                  ));
                                },

and the app keep in this state

Hello, I can't find any documentation regarding using push notifications with this SDK. Is that documented somewhere?

We would like the ability to send custom attachment with custom payload

Example:

For the MessageInput Widget we would need to add customAttachmentActions which is a List of AttachmentActions that would appear alongside the normal attachment button (or maybe provide extra options to customize where it goes, either within the same attachments options or separate with a custom icon, right side, below/above the input box, etc)

{
  type: 'myinfo',
  payload: 
  {
    email: '[email protected]',
    phoneNumber: '555-1234567'
    address: '123 My Avenue East, My City, AA, My Country, P0ST4L'
  }
}

or something like the following attachment:

{
  type: 'mytodo',
  payload:
  {
    title: 'groceries'
    items:
    [
      {
        name: 'pasta',
        completed: 'false'
      },
      {
        name: 'tomatoes',
        completed: 'true'
      }
    ]
}

Note: the actual custom object for attachment can be configured as you guys think is best, this is just an example, I used payload to describe the custom object I'm sending/receiving in my chat.

The idea here is that we can build custom messaging apps, for instance, a chat for groceries apps where you can keep your "to do" list of groceries and send it to your friend and renders a preview in the messages window.

I am using version: 0.2.1-alpha+1.
I am facing some issues.

When we are chatting with each other then after some time message not received and getting exception like this.
Getting error:

1. Message is received but not display the error is like database:

Just like we have a stream for list of channels: Stream<List<Channel>> Will it be possible to have a stream of users like this: Stream<List<User>>. So, we can always have an updated list of users.

Title. Stream is an extremely interesting product and company. Having a flutter package for your other service would lead to much more widespread use, especially considering Flutter's meteoric rise. Are there any plans to do so, or any works-in-progress the community can contribute to?

Hi,

I'm currently trying to figure out how to add members to a channel.

This is the call I'm making but it seems to be resulting in a Dio related error (unable to encode an object)

I'm not really sure if I'm calling the function incorrectly or if this is a problem with Stream Chat. I'd really appreciate any guidance!

Please let me know if you need to see more of my code.

Also it seems the Dart docs are outdated, the way addMembers is called here seems incorrect.

Every time I try to run a project with stream_chat_flutter: ^0.1.23 I get this error when building on iOS.

../../../.pub-cache/hosted/pub.dartlang.org/stream_chat_flutter-0.1.23/lib/src/message_input.dart:655:24: Error: The getter 'MediaType' isn't defined for the class '_MessageInputState'.

Try correcting the name to the name of an existing getter, or defining a getter or field named 'MediaType'.
          contentType: MediaType.parse(lookupMimeType(filename)),
                       ^^^^^^^^^

We have embedded this chat SDK, and now we need to add voice chatting and video chatting, I had read the document, but Voxeet doesn't have a flutter SDK yet. is there any plan of voice chatting and video chatting? Thanks.

gz#5219

I built a sample using your MessageListView widget and I was not getting messages in realtime. Here is a GIF:

This app introduces at least a few capabilities that need to be added to info.plist and other places on iOS.

• Apple notification service
• Photo library
• Contacts?
• Location?
• Speech Recognition?
• Calendars?

I'm not sure what's generating all these requirements in my app. The top two at least are clearly from this package. Could all of the necessary capabilities be listed?

Steps to recreate:

• tap + and "video from camera"
• record a video
• select "use video"
• while the video still has the "loading" gif on top of it, hit send

App crashes. I assume this would also happen for photos if your internet was slow.

Thanks for this integration, as I've said it's the reason we're using Stream. Excited to see how it evolves.

Expected results:

When using Navigator.pushNamed it goes to my own onGenerateRoute from my main.dart

Actual results:

instead it goes to onGenerateRoute inside stream_chat.dart:

child: Navigator(
  initialRoute: '/',
  key: _navigatorKey,
  onGenerateRoute: (settings) {
    return MaterialPageRoute(
      settings: settings,
      builder: (_) => widget.child,
    );
  },
),

When initially type "/" to open the commands overlay, the widget overflows.

Evidence:

Dark Theme seems to be not properly implemented, despite the advertised images on the website.

Using the system theme mode dark (after setting the themes correctly) like this:

Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData.light(),
      darkTheme: ThemeData.dark(),
      themeMode: ThemeMode.system,
      home: Container(
        child: StreamChat(
          client: client,
          child: ChannelListPage(),
        ),
      ),
    );
  }

causes this:

As seen in the image, nothing is dark themed, plus, the message box has white text over white background.
If there's no one working on this, I can fix it and PR, please let me know.

  stream_chat:
    path: ../stream_chat_dart

This path does not exist in the project

is there a way to block a channel so that all of the channel members no longer be able chat on that channel, and the blocked channel did not appear on channel list?

is there a way to disable that panel?

To recreate:

• tap in the text area of the message send box so that the keyboard comes up
• with the keyboard still up, tap the + button for an attachment
• select "photo from camera" or "video from camera"

The keyboard will come up over the camera view. There's no way to escape this without force quitting the app.

Maybe the + button needs to unfocus the text field?

Hello, my team is evaluating Stream and I am very happy with the Flutter and React UI Kits so far. The flutter kit particularly was the big differentiator for us. Kudos!

One problem I was having was that tabbing away from the chat window using BottomNavigationBar tabs caused the Client object to get torn down and the connection to get disconnected, so that when I navigate back to it again I get errors that it has been disconnected.

This is despite the fact that my Client is initialized before runApp .

Root Cause

I found that StreamChat.dispose() calls widget.client.dispose(). This effectively ties the lifecycle of the Client object to the lifecycle of a widget that uses it. From a memory perspective this is not saving anything; in the Stream documentation it is recommended that the Client be created at the top and persist through the lifecycle of the entire app, so it doesn't make sense to dispose of that top level Client object when disposing of a widget that makes use of it.

Workaround

If anyone is experiencing a similar issue, I worked around it by extending the Client class and overriding the dispose method to do nothing:

import 'package:stream_chat_flutter/stream_chat_flutter.dart';
import 'package:dio/dio.dart';

class CustomClient extends Client {
  // Get this from the actual Client source code
  static const _defaultBaseURL = "chat-us-east-1.stream-io-api.com";

  CustomClient(
    apiKey, {
    tokenProvider,
    baseURL = _defaultBaseURL,
    logLevel = Level.WARNING,
    logHandlerFunction,
    Duration connectTimeout = const Duration(seconds: 6),
    Duration receiveTimeout = const Duration(seconds: 6),
    Dio httpClient,
  }) : super(apiKey,
            tokenProvider: tokenProvider,
            baseURL: baseURL,
            logLevel: logLevel,
            logHandlerFunction: logHandlerFunction,
            connectTimeout: connectTimeout,
            receiveTimeout: receiveTimeout,
            httpClient: httpClient);

  @override
  void dispose() {
    // Don't do anything so the connection doesn't get torn down
  }
}

Then, simply use this class rather than Client at the top of your app:

final client = CustomClient(
    'XXX',
    logLevel: Level.INFO,
  );

After this, the StreamChat widget will get torn down and restored as you tab back and forth, but the Client will survive it.

I have not found this to be re-creatable 100% of the time on all devices. One of our iPhones it's hit or miss, another one it happens every time without fail.

Steps to recreate:

• press the + button for attachment
• press "photo from camera"
• take a photo

App is frozen. Force restart needed.

iPhone 11 Max is the one that always freezes. iPhone 7 Plus intermittent.

is there an example about how to initiate one to one conversation?

i got error like this when i call await channel.watch();

E/flutter (19258): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: ApiError{body: Not Found, jsonData: null, status: 404, code: null}

I need to put system_message channel and customer_message channel on the top of channelsPage, but I can't sort by a custom field like priority. Hope support for sorting by custom fields.

gz#4687

We're blocked by the fact that the teams field is missing from a user. Other SDKs have this, and we're working on a multi-tenant/team feature, and we cannot make queries providing the team info of a user.

gz#5458

Given the instability of the attachments feature, there should be a way to not show that attachments button.

When I hide a channel, and channelsListView won't auto display when receiving a message, and I have to refresh channelsListView manually.

gz#5111

is there a tutorial/example/step by step of how to implements push notification on iOS & android?

Just like @mentions it would be great to have #hashtags and have a onHashTagTap as we have for mentions.
