Fix width in Stack to width of first child-CodePudding

I got a Stack-Widget with two childs. The first one is an image, the second one is text. I want to place the text on top of the image, hence the Stack. But when the text is quite long, the text overflows on the left and right. I want it to stay on the image. How can I limit the stacks width to the width of the image?

My Code:

Stack(
  alignment: Alignment.bottomCenter,
  children: [
    ExtendedImage.network(
      UserSession().currentImgURL!,
      fit: BoxFit.fitWidth,
      cache: true,
      cacheWidth: 1000,
      enableMemoryCache: false,
      enableLoadState: true,
    ),
    OutlinedText(
      text: Text(title, style: TextStyle(fontSize: kIsWeb ? 5.sp : 18.sp, height: 1.1)),
      strokes: [
        OutlinedTextStroke(color: Colors.black, width: 5),
      ],
    )
  ],
)

Use Positioned

Example

import 'package:flutter/material.dart';

const Color darkBlue = Color.fromARGB(255, 18, 32, 47);

void main() {
  runApp(MaterialApp(home: MyApp()));
}

class MyApp extends StatefulWidget {
  static MyAppState? of(BuildContext context) =>
      context.findAncestorStateOfType<MyAppState>();

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

class MyAppState extends State<MyApp> {
  final controller = TextEditingController(text: 'ABC');

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Padding(
        padding: const EdgeInsets.all(16),
        child: Center(
          child: Stack(
//           fit: StackFit.expand,
            children: [
              Image.network(
                'https://i0.wp.com/static1.srcdn.com/wordpress/wp-content/uploads/2021/03/Among-Us-Random-Name-Generator.jpg?w=750&ssl=1',
                fit: BoxFit.cover,
              ),
              Positioned(
                left: 0,
                right: 0,
                bottom: 0,
                child: Text(

                  style: TextStyle(color: Colors.white, fontSize: 30),
                ),
              ),
            ],
