Hello!
I came across a problem for which I couldn't find a solution anywhere. I connected the package based on the information described in the documentation.
I would like to receive your help. Thank you in advance.
- I have read the Getting Started and Getting Started(with call invitation)
- I have already searched for the same problem
Environment
| Technology | Version |
|---|---|
| Flutter version | 3.19.5 |
| Plugin version | zego_uikit_prebuilt_call: 4.9.0, zego_uikit_signaling_plugin: 2.7.6 |
| Android version | API 34 |
| iOS version | Not tested |
| macOS version | Not tested |
| Xcode version | Not tested |
| Google Chrome version | Not tested |
Device information:
I tried package on: real device pixel 7 with api 34; emulator pixel with api 34.
Description
Expected behavior:
Opening the call screen on the device; request an incoming call on another device.
Current behavior:
Nothing happens in the UI. The log contains the following error:
'package:zego_uikit_prebuilt_call/src/invitation/internal/internal_instance.dart': Failed assertion: line 21 pos 12: '_pageManager != null': pageManager is null, plugins call ZegoUIKitPrebuiltCallInvitationService().init(...) when user login
Steps to reproduce
- Wrote a service for calls (just divided into modules).
This service includes the implementation of interceptors for different events from the package side and some description of the custom UI.

- Connected the service with libraries

await actions.setOnlyPortraitOrientations();

await actions.extraLoginHandler();

}
- When an autologin or login is made into the application, the method is called
extra_login_handler.dart
Future<void> extraLoginHandler() async {
try {
final currentUser = await firebase_auth.FirebaseAuth.instance.currentUser;
if (currentUser == null) {
return;
}
debugPrint('-- extraLoginHandler - currentUser?.uid: ${currentUser?.uid}');
/// other code
final videocallsService = GetIt.I.get<VideocallsService>();
videocallsService.onUserLogin(
userID: currentUser.uid,
userName: currentUser.displayName ?? 'Unnamed user',
);
} catch (e) {
debugPrint('-- extraLoginHandler');
}
}- When i need to call to another user i call the following method:
start_call.dart
import 'package:app_name/custom_code/custom_lib/features/videocalls/src/services/videocalls_service.dart';
import 'package:get_it/get_it.dart';
Future<void> startCall(
DocumentReference calleeRef,
String calleeName,
) async {
try {
debugPrint('-- startCall - calleeRef: $calleeRef');
final videocallsService = GetIt.I.get<VideocallsService>();
await videocallsService.sendCallInvite(
calleeId: calleeRef.id,
caleeName: calleeName,
);
} catch (e) {
debugPrint('-- startCall: $e');
}
}yoer commented
This is because you haven't executed ZegoUIKitPrebuiltCallInvitationService.init before call, or you executed ZegoUIKitPrebuiltCallInvitationService.uninit it after calling init.
You can try to debug by yourself to see if the assignment is normal (whether the ZegoCallInvitationInternalInstance.registe function is executed and the ZegoCallInvitationInternalInstance.unregiste function is not executed, ZegoCallInvitationInternalInstance is in zego_uikit_prebuilt_call/lib/src/invitation/internal/internal_instance.dart)
You can send the log over to have a look. The log directory is at /sdcard/Android/data/${your_bundle_id}/files/zego_prebuilt/uikit/Logs

It seems I found what the problem is. Indeed, in my service ZegoUIKitPrebuiltCallInvitationService().init simply did not execute because there was an error overriding the final field.
_videoCallDurationModel = VideoCallDurationModel(const Duration(seconds: 0));
Therefore, the error does not actually affect the package.
After I corrected it to
_videoCallDurationModel.update(const Duration(seconds: 0));
The user's call began to be displayed.
Thank you for your help!
Have a nice day!
