The parameter of the Card widget in Flutter is not properly defined

Need help with creating a reusable Card widget in my Dart app. Keep encountering a named parameter is not defined error. Any ideas on what could be causing this issue? Here's what I've attempted so far:

  • Reinstalling the flutter SDK.
  • No issues found when running flutter doctor.
  • Ran a Dart re-analyse in VS-Code.

card.dart

home.dart

import 'package:flutter/material.dart';
import 'card.dart';

class Home extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Card'),
        ),
        body: Card());
  }
}

Answer №1

To avoid conflicts, it is recommended to use a different class name than Card since there is already a Card class in the Dart package.

Here's a solution:

class MyOwnCard extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Card(color: Colors.blue,));
  }
}
