I am having a problem for some days but never get any solution, I tried different approach but not success. I want to pass multiple queryset in the same view or path.

I'm using the example in this link: https://medium.com/@jb.padamchopra/implementing-a-bottom-app-bar-with-floating-action-button-flutter-463560e1324 Widget from the link

I'm new to flutter and I tried calling setState inside the uploadPage widget and try to change clickedCenterFAB but it didn't work. Any idea how to do it guys? thanks for the help in advance.

Here a couple of the Tutorials I've tried.

Kotlin newbie here;

I'm working my way through a tutorial, https://developer.android.com/guide/topics/ui/floating-action-button

I see in a the basic activity sample code a findViewById(R.id.fab), where the part is throwing me off.

I am new to flutter.I have a grid-view with multiple floating-action-buttons. Is there any way I can position my grid-view widget on the y-Axis. I want the grid-view-widget in the middle of the screen. How can I position layouts in flutter in general ?
