typicode_photos
The app name is Typicode Photos because it consumes and renders photos from https://jsonplaceholder.typicode.com/photos
Built with Flutter applying SOLID and Clean Architecture.
Used packages: bloc, hive, retrofit, rxdart, flutter_hooks, connectivity_plus, freezed, dartz, and others.
Technical requirements.
- Create an infinite scroll list with images (use https://jsonplaceholder.typicode.com/photos as the API source).
- Apply the pagination using parameters _start and _limit (e.g. https://jsonplaceholder.typicode.com/photos?_start=15&_limit=15)
- Each image in the list has a title, an image preview, and a like button.
- By tapping on a preview image user is shown a full-sized image in a popup.
- Users can like and unlike images by tapping the like button.
- Like state persists between app launches.
App extra feature using connectivity_plus
With the connectivity_plus plugin help app tries to load automatically
for the next chunk of the data if we had an error and detected the network availability.
The app supports states
- when nothing been loaded, and we are trying to load showing progress
- when nothing been loaded, and we got some network with the message and retry button
- when we have some data loaded, and we are trying to load more automatically showing progress in the very end of the list view
- when we have some data loaded, and we got some network error with the message and retry button in the very end of the list view
- when we have data loaded and reached the end with showing an appropriate message in the very end of the list view
PS: I tried to use the latest infinite_scroll_pagination v3.1.0 package (actual on Mar 6, 2022), but unfortunately, it had one blocking issue amongst others for completing the assignment. Therefore, I decide to implement an appropriate functional by myself.
