In the lib/screens/requestRecipe.dart file, add the code below:

import 'package:easy_localization/easy_localization.dart';
import 'package:flutter/material.dart';
import '../models/recipe.dart';
import '../utils/server2.dart';

class RecipeRequestScreen extends StatefulWidget {
  @override
  _RecipeRequestScreenState createState() => _RecipeRequestScreenState();
}

class _RecipeRequestScreenState extends State<RecipeRequestScreen> {
  final _formKey = GlobalKey<FormState>();
  final _titleController = TextEditingController();
  final _descriptionController = TextEditingController();
  final ApiService _apiService = ApiService();

  @override
  void dispose() {
    _titleController.dispose();
    _descriptionController.dispose();
    super.dispose();
  }

  Future<void> _submitRequest() async {
    if (_formKey.currentState!.validate()) {
      final description = _descriptionController.text;
      final descriptionList = [
        Description(
          type: 'paragraph',
          children: [
            TextContent(
              type: 'text',
              text: description,
              bold: false
            ),
          ],
        ),
      ];
      final request = RecipeRequest(
        title: _titleController.text,
        description: descriptionList,
        id: 0,
      );
      try {
        await _apiService.submitRecipeRequest(request);
        ScaffoldMessenger.of(context).showSnackBar(
          SnackBar(content: Text(tr('request_successful'))),
        );
        _titleController.clear();
        _descriptionController.clear();
      } catch (e) {
        ScaffoldMessenger.of(context).showSnackBar(
          SnackBar(content: Text('Failed to submit recipe request: $e')),
        );
      }
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(tr('request_recipe')),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Form(
          key: _formKey,
          child: Column(
            children: [
              TextFormField(
                controller: _titleController,
                decoration: InputDecoration(labelText: tr('recipe_title')),
                validator: (value) {
                  if (value == null || value.isEmpty) {
                    return 'Please enter a title';
                  }
                  return null;
                },
              ),
              TextFormField(
                controller: _descriptionController,
                decoration: InputDecoration(labelText: tr('description')),
                maxLines: 5,
                validator: (value) {
                  if (value == null || value.isEmpty) {
                    return tr('enter_description');
                  }
                  return null;
                },
              ),
              SizedBox(height: 20),
              ElevatedButton(
                onPressed: _submitRequest,
                child: Text(tr('submit_request')),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

The RecipeRequestPage allows authenticated users to submit a request for a new recipe. widget is a statefull widget managed by the _RecipeRequestPageState class. It uses a form with two input fields: one for the recipe title and one for the description. These input fields are controlled by TextEditingController instances, which manage the text entered by the user.

The _submitRequest method handles the form submission. It validates the form fields, constructs a RecipeRequest object with the entered title and description, and sends it to the server using the ApiService. If the submission is successful, a success message is displayed using ScaffoldMessenger. If there is an error, an error message is shown.

The build method constructs the user interface of the screen and displays the form with its inputs.
