Flutter TextField OutlineInputBorder

Introduction

In Flutter, a TextField is a widget that allows the user to input text. An OutlineInputBorder is a widget that provides a visual border around the TextField.

In this tutorial, we will learn how to add an OutlineInputBorder to a TextField in Flutter. We will use Dart programming language to write the code for the Flutter application.

Steps

1. Create a new Flutter application.

2. Open the main.dart file and add a new TextField widget.

TextField(
    decoration: InputDecoration(
        hintText: 'Enter text',
        border: OutlineInputBorder(
            borderRadius: BorderRadius.circular(10.0),
        ),
    ),
)

Here, we have set the decoration property of the TextField widget to an instance of the InputDecoration class.

The InputDecoration class has a border property that we set to an instance of the OutlineInputBorder class.

We also set the borderRadius property of the OutlineInputBorder class to 10.0.

3. Run the application and verify that the TextField widget has an OutlineInputBorder.

Conclusion

In this tutorial, we learned how to add an OutlineInputBorder to a TextField in Flutter using Dart programming language. This is a simple way to improve the design of your user interface and make it more user-friendly.
