Usage

• In file app.dart, Wrap MaterialApp with PitelVoip widget Please follow example

Note: handleRegisterCall, handleRegister, registerFunc in here

Widget build(BuildContext context) {
    return PitelVoip(                           // Wrap with PitelVoip
      handleRegister: handleRegister,           // Handle register
      handleRegisterCall: handleRegisterCall,   // Handle register call
      child: MaterialApp.router(
        ...
      ),
    );
  }

• In file home_screen.dart. Please follow example. Add WidgetsBindingObserver to handle AppLifecycleState change

...
Widget build(BuildContext context) {
    return PitelVoipCall(
        // Wrap with PitelVoipCall
        bundleId: '${bundle_id}',
        appMode: 'dev', // dev or production
        sipInfoData: sipInfoData,

        },
        goToCall: () {
            // go to call screen
        },
        onCallState: (callState) {
            // IMPORTANT: Set callState to your global state management. Example: bloc, getX, riverpod,..
            // Example riverpod
