Hello @Simplified Coding Bilal Khan. First of all I want to thank you for all the effort and enthusiasm you show toward teaching the techniques of Kotlin and Firebase to us. I might have a friendly feedback If it's OK. Regarding your tutorials I think it's better to show us a brief demo of what you end up as the result of the tutorial video at the beginning of the video so we'll have a picture of the final state of video then it's gonna be easier for us to follow up. Just like for example when someone wants to write an article he writes an abstract to explain briefly about what's covered in the article and then he provides a table of contents demonstrating each section of the article. Your demo doesn't have to be complicated. Even if you show a little hint of what we're gonna watch during the video would suffice. Thank you again and have a great new year.

What did he press at 11:47, that whole screen became blue and class got introduced

[daniela]

I followed part 1 and 2 closely. Insertions work fine. However, when I attempt to populate the ListView and display it, the number of rows of items are displayed but they are empty. If I do a log of a specific value of the item being pulled from the database, it's the default value of null or 0. Why is this?
