Workshop: Flutter Auth Login #part8 send ScreenArguments to EditProfilePage

Create ScreenArguments.dart

class ScreenArguments {
  final String name;
  final String surname;

  ScreenArguments(this.name, this.surname);
}

ProfilePage.dart

import 'ScreenArguments.dart';

@override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('ProfilePage'),

add FormBuider to EditProfilePage.dart and pull name , surename from ScreenArguments

@override
  Widget build(BuildContext context) {
  final screenAgr =
    ModalRoute.of(context)!.settings.arguments as ScreenArguments;
  ...
  FormBuilder(
        key: _formKey,
        initialValue: {
           'name': screenAgr.name,
