setUserId method
Set a user ID.
important
: When the setUserId API is called, if the old userId is not
empty and is different from the new userId, a new session is generated.
If you do not want to use setUserId to identify a user
(for example, when a user signs out), set userId to null.
The SDK does not save the user ID. You are advised to set a user ID each time after the app is launched.
Implementation
Future<void> setUserId(
String? userId,
) async {
await _channel.invokeMethod(
'setUserId',
<String, dynamic>{
'userId': userId,
},
);
}
