Thanks for the timely reply^_^ @dupuchba

I want the following page to be in landscape mode. and when it goes back, flip back to original (portrait) mode.

(def static-route
  (m/Scaffold
   .appBar (m/AppBar .title (m/Text "static monitor"))
   .body
   (f/widget
    :get [m/Navigator]
    :watch [ _ (s/SystemChrome.setPreferredOrientations [s/DeviceOrientation.landscapeLeft]) ;; <=== I don't think it's a good idea
            ]
    m/Center
    (m/ElevatedButton .onPressed #(.pop navigator))
    (m/Text "Go back!"))))

SystemChrome.setPreferredOrientations returns a promise, is there a way to write something like

void main() {
  SystemChrome.setPreferredOrientations(
    [DeviceOrientation.portraitUp, DeviceOrientation.portraitDown]
  ).then((_) {
    runApp(MyApp());
  });
}

Should I use await？

according to documentation it only works on iPad.
These kind of features are OS dependent and are not forced by flutter.
What are the OSes you target?
