Describe the bug
The rpc function does not work.

Reproduction Code
The rpc function in the nakama_grpc_client.dart

  @override
  Future<String?> rpc({
    required model.Session session,
    required String id,
    String? payload,
  }) async {
    final res = await _client.rpcFunc(api.Rpc(
      id: id,
      payload: payload,
    ));

    return res.payload;
  }

Above rpcFunc called in the rpc function, but the session was not used. So the server can not response rightly.
We found the rpc in old version of the repository can work, but the new version does not work.

Expected behavior
The rpc function is useful and expect to work rightly.

Hello,

Can you push a quick fix on the library?

String serverKey='defaultkey',

this.serverKey = 'Basic ${base64Encode('$serverKey:'.codeUnits)}';

https://github.com/obrunsmann/flutter_nakama/blob/64bd5c5219fb1d3d0cc8dd110246141b0e3965e6/lib/src/nakama_client/nakama_grpc_client.dart#L71

[update]
This is not a issue or bug.
For Nakama Console, there are no messages show up by default, I have to Search with any filter or keyword.

The event of websocket listener was able to trigger while the sendMessage excuted and also able to get messageId from ChannelMessageAck but the message seems not displayed on Nakama Console.

(btw, match creation was able to show on Nakama Console)

A part of code

/// joinChannel
myGameController.currentChannel = await NakamaWebsocketClient.instance.joinChannel(target: myGameController.channelName, type: ChannelJoinType.room, persistence: true, hidden: false);

/// sendMessage
Map<String, String> content = {"hello": "world"};
ChannelMessageAck? ack =
        await NakamaWebsocketClient.instance.sendMessage(channelId: myGameController.currentChannel!.id, content: content);

print(ack.toString());
/// ChannelMessageAck(channelId: 2...globalChannel, messageId: 822ca914-75cb-4e8d-9315-7ea32bcb6fd4, code: 0, username: 123456, created: 2022-12-07 16:00:05.000Z, updated: 2022-12-07 16:00:05.000Z, persistent: true, roomName: globalChannel, groupId: , userIdOne: , userIdTwo: )

• List by score
• List by friends
• List leaderboard records around owner
• Submit a score

For example:

listLeaderboardRecords function,

If ownerId parameter is set to exact user id list, It 's ok to return the correct records.

But if ownerId is null or [], or just remove this parameter, It return empty leaderboard records!

Hi,

I can only start a relayed match, is it possible to start an authoritative match? thanks

Just to track this, if somebody experiencing issue with that by chance.

getAccount currently not works in conjunction with device authentication.

Already fixed in develop branch for next release.

Something is failing web support test, though it works with the web compiler:

package:nakama/src/nakama_client.dart that imports:

I created custom match handlers in the backend part for authoritative multiplayer service. The module was loaded successfully but the handlers were not called when I sent the match data through sendMatchData(). As I checked in the official docs (JS SDK), there is sendMatchState() which can communicate through the custom match handlers. I'm not sure the latest version supports this multiplayer type or do I need call other functions for this.

Unity SDK provides isExpired getter and hasExpired(timestamp) method to check if a session will have been expired on the given date. Should add this to dart sdk.

After joining a match/party match/party.presences is available in unity sdk.

It will be great to have this feature and it will be easy to import facebook friends into nakama friend's graph.

As described here:

"You can optionally import Facebook friends into Nakama's friend graph when authenticating. To do this, set import to true."

Unity SDK throws an ApiResponseException in case there is any issue with the API response including StatusCode and Message. I guess it
would be nice to also group all API Exceptions into one SDK owned class which can be handeled by the user:

• HTTP socket exception
• Request timeout
• Abnormal status code
• Runtime errors

As like on the naming conventions → https://dart.dev/tools/pub/package-layout#internal-tools-and-scripts

socket.createMatch('<match name>');

when I make a rpc call using websocket, I can see in the server log that I have the request and the nswer is sent but the flutter app never receive it.

Reproduction Code
Note: This is mandatory! If your issue does not contain it, it will be closed.

Example:

    final result1 = await socketClient.rpc(id: 'hello_world_rpc');

const helloWorldRpc: nkruntime.RpcFunction = function (ctx: nkruntime.Context, logger: nkruntime.Logger, nk: nkruntime.Nakama, payload: string): string {
  return "Hello, World!";
}

Expected behavior
see "hello world " in the flutter debugconsole

Describe the bug
The rpc function does not work.

Reproduction Code
The rpc function in the nakama_grpc_client.dart

  @override
  Future<String?> rpc({
    required model.Session session,
    required String id,
    String? payload,
  }) async {
    final res = await _client.rpcFunc(api.Rpc(
      id: id,
      payload: payload,
    ));

    return res.payload;
  }

Above rpcFunc called in the rpc function, but the session was not used. So the server can not response rightly.
We found the rpc in old version of the repository can work, but the new version does not work.

Expected behavior
The rpc function is useful and expect to work rightly.

hello,

I've tried on a new project and I was not able to receive the data listening on onMatchData.
I can see the server receive the input.

Could be many reason:
The data is not sent to the client
The client doesn't receive the data
The stream is not working
...

Hi there! Thanks for the useful package, unfortunately I'm running into two issues. Firstly, the timestamps for the session expiry seem to be reported incorrectly (at some point in 1970), I believe this is because in session.dart fromMillisecondsSinceEpoch is being called on the decoded token which stores the token in seconds since epoch. Whilst this can be worked around by changing the arguments to (token['exp'] as int) * 1000 in every line where this function is called in the file, I am still getting the message "Auth token invalid" when using any function with the session object (for example addFriends). I'm not sure if this is an issue with the package or the server I'm running, but I thought it could be relevant or maybe caused by the first issue.

I used the official docs and logged using email and then attempted to add a friend to the account using the following:

session = await client.authenticateEmail(
    username: "example",
    password: "example",
);
print(session.expiresAt);
await client.addFriends(
    usernames: ["test"],
    session: session,
);

This gives the following output:

flutter: 1970-01-20 15:29:28.873
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: gRPC Error (code: 16, codeName: UNAUTHENTICATED, message: Auth token invalid, details: [], rawResponse: null, trailers: {})

After applying the fix I mentioned above the session is reported as expiring at the correct date, but the second error still occurs.

I am using flutter 3.13.0 and the latest version of this ibrary on pub.dev, and the latest docker image of nakama. Thank you in advance!

There is a new swagger file available for nakama's REST API: https://github.com/heroiclabs/nakama/blob/master/apigrpc/apigrpc.swagger.json

Problem:
There some chopper updates which are currently making it impossible to just generate a new client. For some reason all new generated methods getting prefixed with the path which should be a chopper config.

When I started working on this project I heavily thought about using chopper or writing REST models by hand. Supporting REST + gRPC in parallel for this package is some kind of a challenge. Now unfortunately there is the downside of this approach, that needs a fix for the chopper config.

I think I would be able to check this on weekend, but cannot promise within just a few hours here.

Nakama actually supports the supplying of a username only instead of an email for authenticateEmail with attemptUsernameLogin = true but the flutter client does not have this functionality and there is no way to supply only a username and email is a required parameter.

Describe the bug
If I pass only the parameters session and name to the listGroups method, the backend throws an exception saying:
GrpcError (gRPC Error (code: 3, codeName: INVALID_ARGUMENT, message: name filter cannot be combined with any other filter, details: [], rawResponse: null, trailers: {}))

Reproduction Code
Example:

 var listGroups = await NakamaClient.instance!.listGroups(
        session: session,
        name: "everyone",
      );

Expected behavior
I expect to retrieve a list of groups, filtered based on the name passed as filter.

Additional context
Considering the error message, it seems like only the name should be passed as filter and cannot be combined.
By using the API explorer through the console interface of Nakama, the endpoint works fine when the name only is passed (and the others are null).
I expect this issue to be in both client files: nakama_grpc_client.dart and nakama_api_client.dart

  @override
  Future<model.GroupList> listGroups({
    required model.Session session,
    String? name,
    String? cursor,
    String? langTag,
    int? members,
    bool? open,
    int limit = defaultLimit,
  }) async {
   final res = await _client.listGroups(
      api.ListGroupsRequest(
        name: name,
        cursor: cursor,
        langTag: langTag,
        limit: api.Int32Value(value: limit),
        members: api.Int32Value(value: members),
        open: api.BoolValue(value: open),
      );
      options: _getSessionCallOptions(session),
    );

    return model.GroupList.fromDto(res);
  }

I also tried to manually pass null to all the parameters but in the name and I confirm this is the behavior the backend expects.

Describe the bug
When we are listening the notifications from the socket, the subject + content is being null, because fromDTO doesn't parse them.

https://github.com/heroiclabs/nakama-dart/blob/main/lib/src/models/notification.dart#L24-L30

Reproduction Code

socket
        .onNotifications
        .listen((notification) {
      print(notification.subject);
      print(notification.content);
    });

It'll give the null values.

Expected behavior
Subject and content are filled with the values.

Solution:

  factory Notification.fromDto(api.Notification dto) => Notification(
        id: dto.id,
        code: dto.code,
        subject: dto.subject,
        content: dto.content,
        senderId: dto.senderId,
        createTime: dto.createTime.toDateTime(),
        persistent: dto.persistent,
      );

Hello,

I have an RPC call on the server, how to get the data back from the server, i.e the response payload?

Hello,

I am running into an issue where the user gets disconnected from the socket either due to idle time or server error. I am not able to find a way to detect that the socket connection is lost and make an attempt to reconnect.
Can you let me know how and where to listen for socket disconnect event and can I simply reconnect using the same NakamaWebsocketClient.init method at that point?

Hello, I'm facing some issues with rpc.

I try to call the rpc async method from the websocket client the Future returns null on every call;
In the server logs I can see that the method has been called.

Can you get a look and tell me what I am doing wrong?

Already implemented, docs are missing.
