I need to optimize a Flutter App for Samsung DeX, without changing the behavior of the app, when is running on a normal Smartphone or Tablet. So my question is, is it possible to detect if an App is running in a Desktop Mode from an Android Device like Samsung DeX?

I already tried using the width of the screen, but this didn't work out, because of the screens of some tablets.

It might help, you can try using the 'Platform.isDesktop' property to check if the app is running in desktop mode.

import 'dart:io' show Platform;

if (Platform.isDesktop) {
  // Running in desktop mode
} else {
  // Running in mobile mode
}

This can be useful for adapting your app's behavior to different screen sizes and input methods.

  • My Platform class from dart:io only contains the following detections: Platform.isAndroid Platform.isFuchsia Platform.isIOS Platform.isLinux Platform.isMacOS Platform.isWindows – linusser Jan 30 '23 at 09:07
  • In that case, you can try the Window.physicalSize property to detect if the app is running in desktop mode. if (Window.physicalSize.width > 1000) { // Running in desktop mode } else { // Running in mobile mode } – Dima C Jan 30 '23 at 09:12

You need use native Android api. In Java/Kotlin, call UiModeManager.getCurrentModeType()(doc). The desktop mode have value 2, which is UI_MODE_TYPE_DESK(doc)

Update: I found a plugin for this: flutter_ui_mode_manager. You can use FlutterUiModeManager.getDeviceUiMode and look for UiMode.UI_MODE_TYPE_DESK
