You don't need a done button just wrap MaterialApp with a GestureDetector

GestureDetector(
  behavior: HitTestBehavior.opaque,
  onTap: () {
    FocusScopeNode currentFocus = FocusScope.of(context);

    if (!currentFocus.hasPrimaryFocus &&
        currentFocus.focusedChild != null) {
      FocusManager.instance.primaryFocus.unfocus();
    }
  },
  child: MaterialApp(
     title: "My title",
     home:MyHomeScreen(),
     ),
);
