Minimum Reproducable code

code

    return FlutterLogin(
      onLogin: (_) {
        return null;
      },
      onRecoverPassword: (_) {
        return null;
      },
    );

I think the bug is realted to AnimatedText or TransformerPageView, but not sure. Here is my minial reproducible code from source:

code

    return Material(
      child: TransformerPageView(
        itemCount: 5,
        transformer: CustomPageTransformer(),
        itemBuilder: (_, __) => ListView(
          children: [
            TextFormField(),
            const Placeholder(fallbackHeight: 500),
            TextFormField(),
            const AnimatedText(
                text: 'somte text'),
          ],
        ),
      ),
    );
