Step 3: 📝 Planning

I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:

Add ability to download country profile as PDF
sweep/download-country-profile-pdf

Description

This PR adds the ability to download a country profile as a PDF in the country_details_page.dart file. It introduces a new PDF service (pdf_service.dart) that handles the PDF generation and integrates it with the existing code. The service is registered in the services_locator.dart file for dependency injection. The country_details_page.dart file is modified to include a button that triggers the PDF generation when clicked. The button calls the PDF service with the necessary data. Additionally, tests are added to ensure the new feature works as expected.

Summary of Changes

• Added pdf_service.dart to handle PDF generation
• Modified services_locator.dart to register the PDF service
• Modified country_details_page.dart to include a button for PDF generation
• Created tests for the new feature

Step 5: 🔁 Code Review

Here are the my self-reviews of my changes at sweep/download-country-profile-pdf.

Here is the 1st review

Thanks for your contribution. There are a few changes that need to be made:

• In lib/core/services/services_locator.dart, please ensure that PdfService is imported at the top of the file. If PdfService requires any arguments for its initialization, they should be provided when it's registered. Also, make sure that PdfService is used somewhere in the code, otherwise, its registration is unnecessary.

• In lib/features/countries/presentation/pages/country_details_page.dart, please import PdfService and locator at the top of the file. If generateCountryProfile requires any arguments other than country, they should be provided when it's called. Also, consider adding error handling for the generateCountryProfile method call to ensure that any exceptions it raises are caught and handled appropriately.

Please make these changes and push them to your branch. Let me know if you have any questions.

I finished incorporating these changes.
