Boa tarde a todos!
Estou tendo um erro de compilação ao tentar obter o name através do state (final name = context.read()< NameCubit >().state;); segue abaixo o código:
class DashboardView extends StatelessWidget {
@override
Widget build(BuildContext context) {
final name = context.read()<NameCubit>().state;
return Scaffold(
resizeToAvoidBottomInset: false,
appBar: AppBar(
title: Center(child: Text('Bytebank - Welcome $name')),
),
body: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Image.asset('images/bytebank_logo.png'),
),
Container(
height: 120,
child: ListView(
scrollDirection: Axis.horizontal,
children: [
_FeatureItem('Transfer', Icons.monetization_on,
onClick:() => _showContactsList(context) ,
),
_FeatureItem('Transaction Feed',
Icons.description,
onClick:() => _showTransactionsList(context)
),
_FeatureItem('Change Name', Icons.person_outline,
onClick:() => _showChangeName(context) ,
),
],
),
)
]),
);
}
}Segue o erro:

The following assertion was thrown building DashboardView(dirty):

If you want to expose a variable that can be anything, consider changing
`dynamic` to `Object` instead.
