requestToken property

EmptyCallback? requestToken

Occurs when the token has expired.

After a token is specified when joining the channel, the token expires after a certain period of time, and a new token is required to reconnect to the server. This callback notifies the app to generate a new token and call RtcChannel.renewToken to renew the token. The EmptyCallback typedef does not include any parameter.

Implementation

EmptyCallback? requestToken;
