flutter / firebase integration

Please note this is an extension to the 2 project you have completed. The goal is to mergerge your listview
you created into the chat project from our original work. This new home_screen.dart would replace the landing page
after login in the chat project.

Using the original chat project we started with, I want to integrate your listview item into that project and
use the user login for this project.

I want to add the json data from our last project to a firebase table. I want to update the field names to the items
listed. Please use the provider package and similar architecture (models and providers) as the original project (chat projects)

The goal I have in this is just to load the datafrom the firebase table where uid = what ever the signed in users id is.

I also want to add a listener to the query in firebase so that when a new record is inserted into the view it show up in
the listview. In addition, when a record is modified, specifically FOOTERICONS, that the listview items footer is redrawn. For
instance, if we add a file icon to an existing record, it would be redrawn in the interface. I want to specifically only redraw the
one list item and not the entire widget tree.

table name: ontxtview
{
"ovid": auto generated
"uid": userid
"header": "Bo",
"body": "Good",
"time": "9:53 AM",
"footerIcons": []
}
