this is Followers View: enter image description here

Answer 1

I had a similar issue with navigation between screens in flutter especially when you download the screen's data from a server you will have to download them every time you go to that specific screen which is not really smooth and fast and there are other problems in navigation, I have used for these issues a dart file in which I have created global variables to (lists, maps, stings...) to save in these variables the data downloaded in each screen and then use them again, you can use these for saving the screen states of any kind of information.
