android – Getting Error (You must set either ‘pages’ or ‘rawPages’ parameter on introduction screen package)

I want to put an introduction screen, I’m using the introduction_screen package, but it gives me an error, this is my code:

This application was working fine until I started adding the induction screen, from then on I can no longer compile the application because the error is occurring.

I created an introductionscreen from the introduction_screen package, the pack version is 3.1.12

class IntrodutionScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: IntroductionScreen(
        globalBackgroundColor: Colors.white,
        scrollPhysics: const BouncingScrollPhysics(),
        pages: [
          PageViewModel(
              titleWidget: Text(
                "Bem vindo",
                style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold),
              ),
              body: "Bem-vindo, esta aplicação vai mostrar todos os eventos realizados na Escola Secundaria Henrique Medina",
              image: Image.asset("assets/Logos/eshm.png",
              height: 400,
              width: 400,
            ),
          ),
          PageViewModel(
              titleWidget: Text(
                "Informaçoes",
                style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold),
              ),
              body: "Para ver mais informações sobre o evento, clique em cima dele",
              image: Image.asset(
                "assets/Logos/eshm.png",
                height: 400,
                width: 400,
              ),
          ),
          PageViewModel(
              titleWidget: Text(
                "Edição",
                style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold),
              ),
              body: "Erraste ao escrever o nome? Não te preocupes podes sempre editar dentro da aplicaçao",
              image: Image.asset(

                height: 400,
                width: 400,
              ),
           
          ),
        ],
        onDone: () {
          Constants.saveIntrodutionInSharedPreference(true);

          Navigator.of(context)
              .pushReplacement(MaterialPageRoute(builder: (_) => Login()));
        },
        onSkip: () {
          Constants.saveIntrodutionInSharedPreference(true);

          Navigator.of(context)
              .pushReplacement(MaterialPageRoute(builder: (_) => Login()));
        },
        showSkipButton: true,
        skip: Text(
          "Skip",
          style: TextStyle(

            color: Color(0xFF17203A),
          ),
        ),
        showNextButton: true,
        next: const Icon(
          Icons.arrow_forward,
          color: Color(0xFF17203A),

        ),
        dotsDecorator: const DotsDecorator(

          spacing: EdgeInsets.symmetric(horizontal: 3.0),
          activeShape: RoundedRectangleBorder(
            borderRadius: BorderRadius.all(Radius.circular(25.0)),
          ),
        ),
      ),
    );
  }
} ```

This error has been happening to me all the time, can anyone help me?

You must set either 'pages' or 'rawPages' parameter
'package:introduction_screen/src/introduction_screen.dart':
Failed assertion: line 340 pos 11: 'pages != null || rawPages != null'
