Error Codes

Sendbird Chat SDK for Flutter has two types of error codes:

Client error codes: these errors are usually caused by something the client app side did, such as incorrect or invalid parameters, or sending a request when disconnected.
Server error codes: these errors are usually caused by a Sendbird server side issue.

Client error codes

The following errors that are defined in error_code.dart are six-digit integers beginning with 800.
