Import 'package:getwidget/getwidget.dart' ![]() You have to install the package from pub.dev, import the package in your Flutter project. Getting started will guide you on how to start building a beautiful flutter application with GetWidget UI library. Now here is the guide about how we should start developing GFRadio Widget with the use of GetWidget UI Library. Here I am going to use an open-source flutter UI Library known as GetWidget to build this Radio option widget in Flutter. So, are you ready to make use of this widget package in the Flutter application? If so, then let's quickly jump into the usage and the ways a Radio can be modified and used to make user-friendly apps. I am going to talk about what is GetWidget Radio widget is and how we implement this on the Flutter app to build an awesome Flutter Radio widget for an app. Radio Button Widget in Flutter With Example When we creating a sample flutter app, it comes with the default scaffold. Therefore before adding a Radio of a widget we need to define a Scaffold. In Flutter, we can define the Radio of widgets inside the scaffold. This is basically a rounded border with having a solid circle inside it, when it is checked otherwise it's just a blank rounded border. ![]() ![]() Users can also use its customized properties to make it elegant. if the user has a yes/no outcome there we can show Radio as checked/unchecked.

We use a generic type T because the value can be any type.Flutter Radio Buttonallows users to make a choice among a list. In addition, we also add label and text properties because we need to display a label on the button and a text on the right side of the button.īelow are the properties and the constructor of the class. When a user selects an option, it's the responsibility of the callback function to update the groupValue. The onChanged property stores the callback function that will be called when the user selects an option. If an option's value matches the groupValue, the option is in selected state. The groupValue property is the currently selected value. The value property represents the value of the option, it should be unique among all options in the same group. Inspired by Flutter's Radio widget, the class has value, groupValue, and onChanged properties. Instead, we are going to create a custom class that can be used the create the options called MyRadioOption. Since the radio button contains a label, we can't use the Radio button. ![]()
