O que esta acontecendo é que algumas tabs passa pelo initState, tanto quando eu avanço para a posterior, tab 4 para tab 5, ou quando eu volto para anterior, da tab 6 para tab 5, tab 5 para tab 4. Mas na tab3, só passa pelo iniState quando ela não existe, da tab 2 para a tab 3. Mas da tab 4 para a 3 não passa pelo initState.

Então e que olhando o código assim me pareceu um pouco confuso você tá usando streams, setState e vi algo ali que me parece um reaction do mobx. Talvez algo esteja causando conflito |

Não sei se vc está usando PageView ou PageView.builder, mas olhando um pouco do código, parece que isso é um problema relacionado com a mudança das tabs no PageView. Se vc puder passar um pouco mais de informações sobre o código, acredito que ajudaria mais. Algumas dicas que tenho em relação a isso: no seu método @override
void initState(){
super.initState();
log('initState has been called');
}
@override
void dispose(){
log('dispose has been called');
super.dispose();Sobre PageView |

Então, propriamente dito nas tabs não esta sendo usado PageView.Builder. class ContentTabHostView extends StatefulWidget {
