createDialogChat method

Future<ChatMixin> createDialogChat(
  1. UserId responderId
)

Creates a Chat-dialog with the provided responderId for the authenticated MyUser.

There can be only one Chat-dialog between two Users.

Authentication

Mandatory.

Idempotent

Succeeds as no-op if a Chat with the given responder User exists already, and returns this Chat.

Implementation

Future<ChatMixin> createDialogChat(UserId responderId) async {
  Log.debug('createDialogChat($responderId)', '$runtimeType');

  final variables = CreateDialogArguments(responderId: responderId);
  final QueryResult result = await client.mutate(
    MutationOptions(
      operationName: 'CreateDialog',
      document: CreateDialogMutation(variables: variables).document,
      variables: variables.toJson(),
    ),
    onException:
        (data) => CreateDialogException(
          (CreateDialog$Mutation.fromJson(data).createDialogChat
                  as CreateDialog$Mutation$CreateDialogChat$CreateDialogChatError)
              .code,
        ),
  );
  return (CreateDialog$Mutation.fromJson(result.data!).createDialogChat
      as ChatMixin);
}
