import 'package:flutter/material.dart';

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

  @override
  State<Technical> createState() => _TechnicalState();
}

class _TechnicalState extends State<Technical> {
  List<String> skill = <String>[];
  List<TextEditingController> mycontroller = <TextEditingController>[];

  @override
  Widget build(BuildContext context) {
    double h = MediaQuery.of(context).size.height;
    double w = MediaQuery.of(context).size.width;

    return Scaffold(
      resizeToAvoidBottomInset: false,
      appBar: AppBar(
        centerTitle: true,
        elevation: 0,
        backgroundColor: Colors.blue,
        title: const Text(
          'Technical Skills',
        ),
      ),
      body: Column(
        children: [
          const Align(
            alignment: Alignment.centerLeft,
            child: Text(
              'Enter Your Skills',
              style: TextStyle(
                fontSize: 20,
                fontWeight: FontWeight.bold,
                color: Colors.blue,
              ),
            ),
          ),
          ...skill
              .map(

                            skill[skill.indexOf(e)] = value;
                          });
                        },
                      ),
                    ),
                    IconButton(
                        onPressed: () {
                          setState(() {

                            mycontroller.clear();
                            print(e);
                          });
                        },
                        icon: const Icon(Icons.delete))
                  ],

              )
              .toList(),
          Center(

The issue is you are creating new controller on every state change, the cursor position is not handling in this.

So the solution will we

controller: TextEditingController.fromValue(
  TextEditingValue(
      text: e,
      selection: TextSelection(
        baseOffset: e.length,
        extentOffset: e.length,
      )),
),

With controller

class _TechnicalState extends State<Technical> {
  List<String> skill = <String>[];
  List<TextEditingController> mycontroller = <TextEditingController>[];

  @override
  Widget build(BuildContext context) {
    double h = MediaQuery.of(context).size.height;
    double w = MediaQuery.of(context).size.width;

    return Scaffold(
      resizeToAvoidBottomInset: false,
      appBar: AppBar(
        centerTitle: true,
        elevation: 0,
        backgroundColor: Colors.blue,
        title: const Text(
          'Technical Skills',
        ),
      ),
      body: Column(
        children: [
          const Align(
            alignment: Alignment.centerLeft,
            child: Text(
              'Enter Your Skills',
              style: TextStyle(
                fontSize: 20,
                fontWeight: FontWeight.bold,
                color: Colors.blue,
              ),
            ),
          ),
          for (int i = 0; i < mycontroller.length; i  ) row_build(i),
          Center(
            child: Text(
              '$skill',
              style: const TextStyle(fontSize: 30),
            ),
          ),
          const Spacer(),
          OutlinedButton(
            onPressed: () {
              mycontroller.add(TextEditingController());
              setState(() {
                skill.add("");
              });
            },
            child: const Icon(Icons.add),
          ),
        ],
      ),
    );
  }

  Row row_build(int i) {
    return Row(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        SizedBox(
          width: 100,
          child: TextField(
            enableInteractiveSelection: true,
            controller: mycontroller[i],
            onChanged: (String value) {
              setState(() {
                skill[i] = value;
              });
            },
          ),
        ),
        IconButton(
            onPressed: () {
              setState(() {
                skill.remove(skill[i]);
                mycontroller.removeAt(i);
              });
            },
            icon: const Icon(Icons.delete))
      ],
    );
  }
}

The textfield works fine for me (left to right)

Check your code if the textDirection property is set correctly to TextDirection.ltr instead of TextDirection.rtl

child: TextField(
   textDirection: TextDirection.ltr,
