fix the error from laravel and flutter

I'm looking to hire an experienced freelancer to fix the error from both my Laravel and Flutter technology. I need the freelancer to have a strong background in the two technologies and be experienced in troubleshooting any issues that arise. In the application, I'm looking for the freelancer to include their experience, past work, and a detailed proposal for this specific project. I'm also open to working with freelancers from outside of my country. If you think you can help me with this project, please get in touch!
