Not working maximum and minimum size for inital time in Linux

[Abdulazeezvp]

for Linux desktop application, setMaximumSize and setMinimumSize not applying while building the app, if hot reload is performed the it is working as expected. setAsFrameless is working which is added along with maximum and minimum function.

initial time:

 setWindow() async {
    if (Platform.isWindows || Platform.isLinux) {
      await windowManager.ensureInitialized();
      windowManager
          .setPosition(Offset(1519, Platform.isWindows ? 478.5 : 518.5)); ///working
      windowManager.setMaximumSize(const Size(380, 540));///not working
      windowManager.setMinimumSize(const Size(380, 540));///not working

      windowManager.setAsFrameless();///working
    }
  }

///if a reload is performed, all working as expected.

I was able to fix it directly in the GTK code in linux/my_application.cc adding:

gtk_widget_set_size_request(GTK_WIDGET(window), 800, 600);
