initState not getting called

[Tony Seng]

I open PageB from PageA using this code

 Navigator.pushNamed(context, PageB.ROUTE);

In pageB, when I press the back device button, it will return to pageA, but the initState in PageA is not getting called. Why? I want it call a function once it is back from pageB.

[Andy Greenshaw]

Because PageA already exists on the stack. It is not being recreated, so initState is not called again.

You could do 

 await Navigator.pushNamed(context, PageB.ROUTE);

// now here do whatever you like to update PageA (eg setState)
