I just looked into it and it works properly. Is any possible that reason impacting?
What I do is dragging the list viewer into the screen, and link it with firebase. To double check the connection with firebase, I have changed the label to the length of the list. However, only label is successfully shown. I have also checked the visibility of the list and it is “true”.
There shouldn’t be any problems. Check the dimensions and layout of the components. Add several rows to the properties panel in List Viewer. Is it now displayed on Android?
