how to prevent setState from rebuild in flutter

Question

is there a way to prevent setState to rebuild? because I have to show my state inside widget Text but whenever I click another tab and back again to my main screen... the state always re-build and I am getting null

is there another method, so that whenever I click another tab... I can still access my last data — wahyu, Apr 22 '20 at 09:50

Are you using a PageView by any chance? Could we see your widget tree to get some context? — Apps 247, Jun 02 '21 at 06:47

you can use AutomaticKeepAliveClientMixin to save the state of app.

@override // TODO: implement wantKeepAlive bool get wantKeepAlive => true;

using this constuctor.
