title: Flutter textformfield cursor moving to front of the text
body: <p>I am using a textformfield in my application. The cursor keeps moving to the left most side of the text. To solve this issue I added a listener:</p>
  <pre><code>  final TextEditingController _controller = TextEditingController();
  
    @override
    Widget build(BuildContext context) {
      _controller.text = widget.localLayoutItem.cx.toInt().toString();
      _controller.addListener(() {
        _controller.value = _controller.value.copyWith(
          text: _controller.text,
          selection: TextSelection.fromPosition(TextPosition(
            offset: _controller.text.length,
          )),
          composing: TextRange.empty,
        );
      });
      return Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          TextFormField(
              controller: _controller,
              decoration: const InputDecoration(
                border: InputBorder.none,
                contentPadding: EdgeInsets.only(left: 10),
                iconColor: Colors.grey,
              ),
              onChanged: (value) {
                FocusedItemModel.of(context).redraw();
                widget.localLayoutItem.cx = double.parse(value);
             },
          ),
        ],
      );
    }
  </code></pre>
  <p>The textfield value is directly connected to the widgets x-axis value so if the widget moves I need to update the textfield value as well and vice-versa.</p>
  <p><strong>Problem:</strong>
  After adding the listener the cursor is staying on the right most but I lost functionality like using the arrow key to a desired character or deleting all characters.</p>
  <p>how to solve this issue?</p>
