how to add one text in center and another in bottom in flutter>

This is the simple implementation of your design, I prefer you to searching on youtube/any other learning platform for learning flutter

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: Scaffold(
          backgroundColor: const Color.fromARGB(255, 41, 120, 88),
          body: SafeArea(
            child: Container(
              child: Stack(
                children: [
                  Center(
                    child: Container(
                        child: const Text(
                      "Gets you Job.",
                      style: TextStyle(
                          color: Colors.white,
                          fontWeight: FontWeight.w700,
                          fontSize: 36),
                    )),
                  ),
                  Align(
                    alignment: Alignment.bottomCenter,
                    child: Container(
                        child: const Text(
                      "c Intropros Technologies",
                      style: TextStyle(
                        color: Colors.white,
                      ),
                    )),
                  )
                ],
              ),
            ),
          ),
        ),
     );
   }
 }

there’s a lot of learning platform right now, udemy, youtube, and you can read flutter documentation too.
