I have an application like this:

I want to place a Text widget at the bottom of the page. How can I do that?

Codes:

import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:teen_browser/pages/LoginAndRegister/LoginPage.dart';
import 'package:teen_browser/pages/LoginAndRegister/RegisterPage.dart';
class RegisterPage extends StatelessWidget {
  const RegisterPage({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: const Color.fromARGB(255, 25, 25, 25),
      body: SingleChildScrollView(
        child: Column(

                      ),
                    ),
                    child: const Text("Hesap Oluştur", style: TextStyle(color: Colors.white, fontSize: 20, fontFamily: "Montserrat")),
                    onPressed: () {},
                  ),
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }
}

I tried with code like this:

Align(
  alignment: Alignment.bottomCenter,
  child: Text("Test"),
),

But this code didn't work. He settled into the regular Column row. It's not at the bottom of the page.

Thanks for help.

Using another column with MainAxisAlignment.spaceBetween, works, also you can replace MediaQuery size with `LayoutBuilder.

class RegisterPage extends StatelessWidget {
  const RegisterPage({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: const Color.fromARGB(255, 25, 25, 25),
      body: LayoutBuilder(
        builder: (context, constraints) => SingleChildScrollView(
          child: SizedBox(
            height: constraints.maxHeight,
            child: Column(
              mainAxisAlignment: MainAxisAlignment.spaceBetween,
              children: [
                Column(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    SizedBox(
