My Flutter API request code review

I am currently looking for a job as a junior Flutter engineer, and this was the test question I received. -------------------------------- Task: Design a simple thumbnail image presentation app using a state management method like Bloc, Riverpod, GetX, or another. Base API: [login to view URL] Endpoint: /photos First Page: Only requires a button to transition to the next page. Second Page: Present the content from the API, with three required items: "id," "title," and "thumbnailUrl."The "thumbnailUrl" is the URL for the image, which should be displayed in the imageView within each cell, with four cells per row. The UI should automatically adapt to different iPhone screen sizes. Requirements: The app should function correctly, with images displaying properly during scrolling. Implement a state management framework. Bonus Points: Local Database. Unit testing. -------------------------------- I submitted my work, but it was ultimately rejected for "not using the DAO or Repository pattern to handle the switch between Network/Local services." I would like to ask for an evaluation of my code to understand the quality of my work. Also, I would appreciate guidance on how to improve my code using the DAO or Repository pattern. Thank you. Here is my code.

Direct message me with the issues you have identified so far and the recommendations you plan to make.
