Taking into account that you want to pass the value of the parameter via constructor would be:

void main() => runApp(Checkbox('meu parametro'));

class Checkbox extends StatelessWidget {
  Checkbox(this.title);
  final String title;
  // final String value ='CheckboxValue';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page ' + title),
    );
  }
}
