What does the Flutter Video Calling SDK include?
The Flutter Video Calling SDK provides TUICallEngine APIs for call invitations, events, and media controls. Your application builds the Flutter call screen and connects it to Dart call state.
Should I use a Flutter call SDK or UI Kit?
Use the SDK APIs to build your own interface. Choose the UI Kit when you want ready-made screens and controls.
How do incoming Flutter calls work in the background?
Configure the native push and application lifecycle requirements in the Flutter guide. Test foreground, background, and offline incoming calls on real devices; displaying a call screen alone does not complete that setup.
How do I authenticate users of the Flutter Video Calling SDK?
Create a UserSig on your server and pass it to the client after your own sign-in flow. Keep the application secret on your server.
Is the Flutter Video Calling SDK free to use?
The interface and the hosted Call service have different roles. Activate the service for your application and review the current plan, feature availability, and usage charges.
How do I integrate Flutter Video Calling SDK with Dart?
Install the documented Flutter package and complete native project configuration for each target. Test widget lifecycle together with the underlying iOS and Android behavior.
How do I test Flutter Video Calling SDK before releasing my app?
Test invitation, accept, decline and end-call state between independent users, including permission denial.
How do I customize the interface for Flutter Video Calling SDK?
Build call controls and participant views around the supported state and media APIs; your app owns the interface.
