Tabview flashing transition #1567

I'm encountering a problem with the 'Tab Navigation' template of Nativescript (V4) with Angular, forAndroid, on emulator (Nougat v7.1.1) or on the device (Oreo 8.1).

When I navigate between tabs, the screen "flashes". The behavior seems linked to the use of several "page-router-outlet".

I tried the solution described Nativescript Forum, without success.

With the <item name=“android:windowAnimationStyle”>@null</item> in AppThemeBase, I encounter an error of the type

System.err: com.tns.NativeScriptException:
System.err: Calling js method onViewAttachedToWindow failed
System.err:
System.err: TypeError: Cannot set property 'transitionType' of null
(both on emulator or device).

a little video showing the problem

I have create a StackOverflow question with no success : https://stackoverflow.com/questions/52854414/nativescript-tabview-flashing-transition
