Navigator.pop seems to be triggered on orientation change - flutter

Question

I have a page where the camera starts and I can record a video. The problem is when I rotate the camera. Then I end up in the main page. This also happens if I navigate to other pages and the change orientation.
Before adding the camera feature I enforced portrait mode so I did not discover this behaviour.
How can I avoid Navigator.pop when the orientation changes?
I am btw a rookie in Flutter.
EDIT: I have tried some different approaches, like adding WillPopScope. However, that is not triggered when rotating the camera.
It does work to navigate to the camera view using this approach:
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(builder: (context) => CameraView()),
(Route<dynamic> route) => false,
);
But then there is no back button...
How can this be so complicated?
This is how I add navigation in the HomePage:
Widget startResultButton() {
return Padding(
padding: const EdgeInsets.all(5),
child: FractionallySizedBox(
widthFactor: _buttonWidthFactor,
heightFactor: _buttonHeightFactor,
child: TextButton(
style: getStyle(buttonColor),
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) {
return const ResultsMenuView();
},
),
).then((value) => _updateDisplay());
},
child: Row(
children: [
Flexible(child: getSvg("prev_sessions.svg")),
const Flexible(
child: Text(
"Analyse results",
textScaleFactor: textFactor,
)),
],
mainAxisAlignment: MainAxisAlignment.start,
),
),
),
);
}
And the ResultMainView looks like:
class ResultsMenuView extends StatelessWidget {
const ResultsMenuView({Key? key}) : super(key: key);
final double _buttonWidth = 0.9;
final double _heightFactor = 0.6;
Widget getBody() {
var sessionChart = Flexible(
child: NavigationButton(
"Session Overview",
buttonColor,
const SessionOverviewChart(),
_buttonWidth,
_heightFactor,
"overall_results.svg"),
);
var detailedChart = Flexible(
child: NavigationButton(
"Detailed Scores",
buttonColor,
const DetailedChartView(),
_buttonWidth,
_heightFactor,
"detailed_results.svg"),
);
var tableView = Flexible(
child: NavigationButton("History", buttonColor, const TableView(),
_buttonWidth, _heightFactor, "prev_sessions.svg"),
);
var trendCurveButton = Flexible(
child: NavigationButton(
"Trend Curve",
buttonColor,
const TrendCurveView(),
_buttonWidth,
_heightFactor,
"trend_curve.svg"),
);
return Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [sessionChart, detailedChart, trendCurveButton, tableView],
),
);
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: buttonColor,
title: const Text("Results Menu"),
),
body: SafeArea(
child: getBody(),
),
backgroundColor: backgroundColor,
);
}
}
