How to handle Ngrx loading when browser back button..it will hit again replacing the state Object

[Naveenshri]

M calling service in my component
For example
m calling service ngInit to assign the state as well
ngInit() {
here based on some condition dispatch the Action assign in the state objects
dispatch action(customer Id)
}
In that page m having sub pages as well when i click navigate another page and come back previous page again,using browser back button or click back button.

NgOnit again called to replace the state object

Expected:when i come previous page to parent page instead of hitting the service again i will get state to assign my component

How to avoid calling ngInit() ?

kindly give me the solution for that behavior
