Flutter TextField Cursor Position

The cursor position in a Flutter TextField can be obtained by using the TextEditingController and its selection property.

Here’s an example:


import 'package:flutter/material.dart';

class MyTextField extends StatefulWidget {
  @override
  _MyTextFieldState createState() => _MyTextFieldState();
}

class _MyTextFieldState extends State {
  TextEditingController _controller = TextEditingController();
  
  @override
  void initState() {
    super.initState();
    _controller.addListener(_cursorListener);
  }
  
  void _cursorListener() {
    final cursorPosition = _controller.selection.start;
    print('Cursor position: $cursorPosition');
  }
  
  @override
  Widget build(BuildContext context) {
    return TextField(
      controller: _controller,
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      body: Center(
        child: MyTextField(),
      ),
    ),
  ));
}

In this example, we create a custom MyTextField widget that extends StatefulWidget. Inside the widget’s state, we define a TextEditingController named _controller and set up a listener using addListener.

The _cursorListener method listens for changes in the _controller and retrieves the cursor position via its selection property. The cursor position is then printed to the console.

When the app is run, the MyTextField widget is displayed, and whenever the cursor is moved within the text field, the new cursor position is printed to the console.
