Creating an Editable TextField in Flutter

When developing applications in Flutter, creating a user-friendly interface is key to improving user experience. One common requirement is having a TextField that can toggle between edit and display modes. In this post, we'll dive into a practical solution for making a TextField editable using a suffix icon, allowing users to enter or modify text conveniently.

The Problem

You may encounter a scenario where your TextField initially works, allowing edits upon clicking a pen icon. However, if the TextField becomes non-editable and the icon is disabled, it may lead to confusion. This can happen if you have linked the enabled property of the TextField to a boolean value wrongly or placed the icon button inappropriately, causing it to become non-functional.

The Solution

To make your TextField function as intended, follow the instructions below to separate the icon button from the TextField and control the editability effectively. Let's break down the solution into clear steps.

Step 1: Initialize Your Controller

Start by initializing the TextEditingController and defining a boolean for editability. This helps manage the state of the TextField.

Step 2: Create the Layout

Layout your TextField and the suffix icon button using a Row. It is essential to position them such that the icon can be clicked independently from the TextField.

Step 3: Update the UI with State Changes

With this organization, when you click the pen icon, it should now properly toggle the isEditable state to true, allowing you to edit the TextField. The key is to separate the IconButton from the TextField so that its action does not disable the text input.

Conclusion

By separating the IconButton from the TextField and managing the isEditable state properly, you can create an effective, user-friendly editable text field in Flutter. This approach not only enhances usability but simplifies your code structure.

Feel free to implement this in your Flutter applications and watch as it significantly enhances the interactivity of your forms!
