Details

init

This API is used to initialize TUICallEngine. Call it to authenticate the call service and perform other required actions before you call other APIs.
Future<TUIResult> init(int sdkAppID, String userId, String userSig)

unInit

The destructor function, which releases resources used by TUICallEngine.
Future<TUIResult> unInit()

addObserver

This API is used to register an event listener to listen for TUICallObserver events.
Future<void> addObserver(TUICallObserver observer)

removeObserver

This API is used to unregister an event listener.
Future<void> removeObserver(TUICallObserver observer)

This API is used to make a (one-to-one) call.
Future<TUIResult> call(String userId, TUICallMediaType mediaType, TUICallParams params)
Parameter
Type
Description
userId
String
The target user ID.
mediaType
The call type, which can be video or audio.
params
An additional parameter, such as roomID, call timeout, offline push info, etc

groupCall

This API is used to make a group call.
Notice：
Before making a group call, you need to create an IM group first.
Future<TUIResult> groupCall(String groupId, List<String> userIdList, TUICallMediaType mediaType, TUICallParams params)

Type
Description
groupId
String
The group ID.
userIdList
List<String>
The target user IDs.
mediaType
The call type, which can be video or audio.

reject

This API is used to reject a call. After receiving the onCallReceived() callback, you can call this API to reject the call.
Future<TUIResult> reject()

ignore

This API is used to ignore a call. After receiving the onCallReceived(), you can call this API to ignore the call. The caller will receive the onUserLineBusy callback.
Note: If your project involves live streaming or conferencing, you can also use this API to implement the “in a meeting” or “on air” feature.
Future<TUIResult> ignore()
