Flutter - Create dynamic number of texteditingcontrollers

Question

I am recreating an app I have previously made in Swift, and on one of my pages we call an API and based on the results, we present the user a dynamic number of textfields to

More or less as @Günter Zöchbauer mentioned, you can just build a list of widgets which are nested then in a container.

Here's a simple example:

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: "MyHomePage",
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(
        title: "MyHomePage",
      ),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final title;

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

class _MyHomePageState extends State {
  @override
  Widget build(BuildContext context) {
    var stringListReturnedFromApiCall = ["first", "second", "third", "fourth", "..."];

    // This list of controllers can be used to set and get the text from/to the TextFields
    var textEditingControllers = [];

    var textFields = [];
    stringListReturnedFromApiCall.forEach((str) {
      var textEditingController = new TextEditingController(text: str);
      textEditingControllers.add(textEditingController);
      return textFields.add(new TextField(controller: textEditingController));
    });

    return Scaffold(
        appBar: AppBar(
          title: Text(widget.title),
        ),
        body: SingleChildScrollView(
            child: new Column(
          children: textFields,
        )));
  }
}

Edit: Added list for TextEditingControllers to interact with all the TextFields
