How to Set Cursor Position at the End of the Value in Flutter TextField? 🖱️

Are you having trouble setting the cursor position at the end of the value in a Flutter TextField? You're not alone! Many developers face a common issue where the cursor moves to the starting point of the value in the TextField on Android devices. This can be frustrating, especially if you're trying to add some additional text at the end, like ,00.

But fear not! In this blog post, we'll explore some easy solutions to this problem and help you set the cursor at the end of the value in your Flutter TextField. Let's dive in! 💦

The Problem: Cursor Position Anomaly 🧐

The problem occurs when you try to add ,00 at the end of the value in a TextField. While it works perfectly fine on iOS devices, on Android, the cursor unexpectedly moves to the starting point of the value. This makes it impossible to add the desired ,00 at the end.

Solution 1: Using a TextEditingController 📝

One way to solve this issue is by utilizing a TextEditingController. This Flutter class allows you to control the text in a TextField and access or modify its current value. Here's how you can use it to set the cursor at the end:

TextEditingController _textFieldController = TextEditingController();

TextField(
  controller: _textFieldController,
  onChanged: (value) {
    // Your code here
  },
)

// In your code where the `,00` needs to be added
_textFieldController.text = _textFieldController.text + ',00';
_textFieldController.selection = TextSelection.fromPosition(
  TextPosition(offset: _textFieldController.text.length),
);

By setting the text of the TextEditingController and adjusting the selection position, you can ensure that the cursor remains at the end of the TextField value, even on Android devices.

Solution 2: Using focusNode.requestFocus() 🔍

If you still encounter issues with the cursor position after implementing Solution 1, an alternative approach is using the focusNode.requestFocus() method. Here's how you can apply this solution:

TextEditingController _textFieldController = TextEditingController();
FocusNode _focusNode = FocusNode();

TextField(
  controller: _textFieldController,
  focusNode: _focusNode,
  onChanged: (value) {
    // Your code here
  },
)

// In your code where the `,00` needs to be added
_textFieldController.text = _textFieldController.text + ',00';
_focusNode.requestFocus();

By focusing on the TextField using the focusNode.requestFocus() method after modifying the text, you can ensure that the cursor is placed at the end of the value, providing a smooth user experience.

Conclusion and Call-to-Action 🙌

By following these simple solutions, you can easily set the cursor position at the end of the value in a Flutter TextField, regardless of the device you're working on.

⚡ Next time you encounter this issue, remember to try Solution 1 using the TextEditingController or Solution 2 by utilizing the focusNode.requestFocus() method. Experiment with both approaches and see which one works best for your specific use case.
