How to Disable Keyboard Popup on TextField in Flutter

**Hey there, Flutter developers!**

Have you ever tried to type in a `TextField` in your Flutter app, only to be bothered by that pesky keyboard popup that steals the focus from your form? Yeah, it can be super frustrating!

Don’t worry, I’ve got you covered! In this post, we’re going to learn how to disable that keyboard popup on your `TextField` in Flutter. It’s easier than you think!

**The problem**

When a `TextField` is focused, the keyboard popup appears automatically to enable users to input text. While this is usually helpful, sometimes you might want to prevent the popup from appearing in certain situations, like when you’re dealing with a complex form or when you want to implement a custom keyboard solution.

**The solution**

To disable the keyboard popup on your `TextField`, you can use the `keyboardType` property and set it to ` TextInputType.none`. This will prevent the keyboard from appearing when the `TextField` is focused.

Here’s an example of how to do it:
“`dart
TextField(
keyboardType: TextInputType.none,
// Other properties…
)
“`
By setting `keyboardType` to `TextType.none`, you’re essentially telling Flutter to ignore the default keyboard behavior for this `TextField`. This means that the keyboard popup won’t appear when the `TextField` is focused.

**But wait, there’s more!**

If you want to prevent the keyboard pop up only when your app is running on a specific platform (like iOS or Android), you can use the `PlatformChannel` package and check the platform before setting the `keyboardType`.

For example:
“`dart
import ‘package:flutter/services.dart’;

TextField(
keyboardType: Platform.isIOS ? TextInputType.none : TextInputType.text,
// Other properties…
)
“`
In this example, we’re using the `PlatformChannel` package to check if the app is running on an iOS device. If it is, we set the `keyboardType` to `TextType.none`. If not, we set it to `TextType.text`.

**Conclusion**

And that’s it! With just a few lines of code, you can disable the keyboard popup on your `TextField` in Flutter. Whether you’re dealing with a complex form or implementing a custom keyboard solution, this trick will come in handy.

I hope this post helps you avoid those annoying keyboard popups and makes your development experience more enjoyable!
