crossAxisAlignment: CrossAxisAlignment.end doesn't work

Question

I am pretty new to programming and also to Flutter, so please excuse me if my question is silly. I am trying to push Skip button to the bottom left corner of the screen. But the crossAxisAlignment: CrossAxisAlignment.end code doesn't work. How could I do this the right way so it can adapt to all screen formats properly? The problematic part is at the bottom of the entire code. Thank you in advance!

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MainPage(),
    );
  }
}

class MainPage extends StatefulWidget {
  const MainPage({Key? key}) : super(key: key);

  @override
  _MainPageState createState() => _MainPageState();
}

class _MainPageState extends State<MainPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(

Answer 1

To change the position for Row children horizontally you need to use mainAxisAlignment property

mainAxisAlignment property: How the children should be placed along the main axis. For example, MainAxisAlignment.start, the default, places the children at the start (i.e., the left for a Row or the top for a Column) of the main axis.

Answer 2

You can use Spacer widget before Row. By default, row children will start from left.

 ///others widgets 
 const Spacer(), /// just add this
 Row(....
