### Nested Navigators
|
|
|
|
Going a little further, it's possible to have nested navigators. The `Navigator` has a `level` property (so you can check how deeper your are) and can have a `parent` navigator (if you need to interact with it).
|
|
|
|
```kotlin
|
|
setContent {
|
|
Navigator(ScreenA) { navigator0 ->
|
|
println(navigator.level)
|
|
// 0
|
|
println(navigator.parent == null)
|
|
// true
|
|
Navigator(ScreenB) { navigator1 ->
|
|
println(navigator.level)
|
|
// 1
|
|
println(navigator.parent == navigator0)
|
|
// true
|
|
Navigator(ScreenC) { navigator2 ->
|
|
println(navigator.level)
|
|
// 2
|
|
println(navigator.parent == navigator1)
|
|
// true
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Another operation is the `popUntilRoot()`, it will recursively pop all screens starting from the leaf navigator until the root one.
