Building a Shopping List App: Jetpack Compose and Room Database- UI layer

[@saisainghminetun8884]

Thanks a ton! I'm having difficult time understanding Room DB and this video really helps me alot.

[@mudlark26]

Thank you for this tutorial series. I'm new to android studio and it's helping me so much.

[@HoodLabs]

You are welcome.

The tutorial is very good. It includes a lot of details and features that you make seem easy. Now since this tutorial is close to a year old and being that Kotlin is a such a dynamic language, there are parts that are tricky, and much patience is needed. The depository in Github is very helpful to verify the accuracy of the code input; however there seems to be files missing. Would it be too much to ask, to verify that all the files are present in Github, please? And thank you again for your dedication to the propagation of Android development.

[@HoodLabs]

Have you tried changing the branch on GitHub it contains all the files.

[@junlapunete1602]

Please can you provide the complete source code of this tutorial?

[@mazighus]

It is better to create a final solution for the project to compare it with our project to fix errors

The resolution of the video is only 360p is that something KZbin takes care of soon?

[@HoodLabs]

Yes, sometimes KZbin takes longer to process a video to higher qualities.

I don't understand where is the data coming from ?! he created the data layer and the ui later but from where is the data being filled?

[@ubersticks]

At 44:06 you are creating addListItem() but using Category id and title as if they are ShoppingList id and name -- very confusing to me. Maybe you fix this later, but it seems strange at this time.

[@HoodLabs]

When you look at the models we have a shopping list, item and store so the first represent a bucket containing items to shop i.e electronics category saved as a shopping list bucket contains items for phone,Tv, radio and etc thus we use the id for a category to save it as shopping list id.

[@HoodLabs]

So the categories is hard coded for simplicity you can make it dynamic so users can create their own shopping list(bucket) as how we have done on stores users add them.

The data/items repopulates when app is closed and then reopens. i cannot find a solution to this on stack.

[@brianduncan3900]

after deleted, it repopulates when app is reopened.

[@HoodLabs]

I think you're not deleting the data directly from database so you're just removing them from the state when swiping it will be repopulated from database. Check that your calling from a method to delete from your repository is calling a method from the Dao.
