💭 Diary
I finally solved the obstacle that blocked me in SMA lecture 2/22.
- In the lecture,
Likes bywas handled with a users query Single Document, so every child in the ListView printed the same name. - After properly studying and understanding the
Document Referenceconcept, I realized how to extract the users Collection from theliked_usersitem provided after Dynamic Children Generation in ListView. - Implementation complete.

There were users in the comments complaining about the same issue, but the problem had been left unanswered. That did not look good. If I develop an app or record a course later, I should never ignore user feedback.

My skills are still lacking, but I left a comment to help others.
Listening to feedback and practicing information sharing will eventually return to me in a big way. Maybe these are essential virtues for developers.
