[sysarcher]

@dirugec can you provide a minimal example? I can add a row... (copy-paste into your main.dart file...

(though as you might notice, I have another problem: namely, the global state isn't updated which I'm struggling with right now)

import 'package:flutter/material.dart';
import 'package:editable/editable.dart';

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

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      // Application name
      title: 'Flutter Hello World',
      // Application theme data, you can set the colors for the application as
      // you want
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      // A widget which will be started on application startup
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final String title;

  MyHomePage({@required this.title});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Create new row',
      home: MyCustomForm(),
    );
  }
}

class MyCustomForm extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return testForm();
  }
}

class testForm extends StatefulWidget {
  @override
  _testFormState createState() => _testFormState();
}

class _testFormState extends State<testForm> {
  /// Create a Key for EditableState
  final _editableKey = GlobalKey<EditableState>();

  List cols = [
    {
      "title": 'Inputs',
      'widthFactor': 0.2,
      'key': 'input'
    },
