Below shows the image of the items in the vertical gallery in Powerapp:

Below is the image of the screen for checklists content:

This is the sample data:

Desire outcome: For instance, if I select "office" item in the vertical gallery, it should navigate me to a screen showing the checklists for the office. Let's say if I go back and select "Meeting room" item in the vertical gallery, it should navigate me to the SAME screen showing the checklists for the meeting room. In short, I want to on list item select to navigate me to the same screen and change the content (checklists) of the screen dynamically.

You can access the selected row of the gallery with Gallery.Selected from the checklists screen. This will give you access to the selected row/record in the data source that is feeding the Gallery control on the first screen.
