Using drawer to change TabBarView

Question

I have a TabBar which has 19 items, swiping trough them works fine and works as intended.

Issue I have is when the controller.index jumps from more than 1 index, like this:

I also noticed that when I set the controller.index where index is more than 1, the http request is called 3 times.

I/flutter (18372): https://www.subotica.info/restful-najava-za-danas?page=0
I/flutter (18372): https://www.subotica.info/restful-latest?page=0 // the category i clicked on
I/flutter (18372): https://www.subotica.info/restful-najava-za-danas?page=0

So first time it calls on the controller.index + 1 then the one I actually selected and once again on controller.index + 1

Setting it inside a drawer:

 ListTile(
                    title: Text(NewsConstant.latestNews),
                    onTap: () {
                      setState(() {
                        controller.index = 0;
                        Navigator.of(context).pop();
                      });
                    }),

Answer 1

I found out that I have to iterate it one by one

   ListTile(
                    title: Text(NewsConstant.cultureNews),
                    onTap: () {
                      setState(() {
                        pageNumber = 0;
                        for(int i=controller.index; i<3 ;i ++)
                        controller.index++;
                        Navigator.of(context).pop();
                        isFresh = api.isFresh();
                      });
                    }),

Just have to make a function for every category
