Introduction
As a Flutter developer, you may have faced a situation where you need to create stylish rounded buttons. A rounded button can give your user interface a modern and elegant feel that is visually appealing and easy to use. But how can you create these buttons with ease, and what is the best method?
In this post, we will cover the steps to craft stylish rounded buttons with border-radius in Flutter. We will walk you through each step of the process, sharing valuable tips, insights, and code snippets. By the end of this article, you will have a solid understanding of how to make beautiful buttons that will enhance your Flutter projects.
Section 1: Why Rounded Buttons are Popular in User Interface Design?
Rounded buttons are a popular choice for user interface design because they offer several advantages over traditional rectangular buttons. Some of the main benefits of rounded buttons include:
– Rounded buttons are visually appealing and modern-looking, making them ideal for mobile apps, websites, and other digital products.
– Rounded buttons are easier to tap and click on, especially for users with larger fingers or those using touch screens.
– Rounded buttons can convey a sense of friendliness and approachability, helping to build a positive user experience.
Now that we know the benefits of rounded buttons let’s dive into how to create them in Flutter.
Section 2: Setting up the Flutter Environment
Before we start creating rounded buttons, we need to set up our Flutter environment. If you have already set up Flutter environment skip this section.
– Download and install the Flutter SDK from the official Flutter website.
– Once the SDK is installed, add the Flutter bin directory to your system’s path.
– Launch your IDE (Integrated Development Environment) and create a new Flutter project.
Once we have set up our Flutter environment, we can now move on to the next step.
Section 3: Creating a Rounded Button with Border-Radius
To create a rounded button with border-radius in Flutter, we need to use the RawMaterialButton widget. Here are the steps to create a rounded button:
– Add the following code to your Flutter project:
“`dart
RawMaterialButton(
onPressed: () {},
fillColor: Colors.blue,
splashColor: Colors.lightBlueAccent,
elevation: 5.0,
child: Text(
‘Button’,
style: TextStyle(color: Colors.white),
),
padding: EdgeInsets.symmetric(horizontal: 20.0, vertical: 10.0),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.blue)),
);
“`
– In the code above, we are using the RawMaterialButton widget to create a button with a blue fill color, a light blue splash color, and an elevation of 5.0. We have also added some padding to the button to make it look more appealing.
– The most important part of this code is the shape property. We are using the RoundedRectangleBorder widget to create a rounded button with a circular border-radius of 18.0. The side property specifies that the button has a blue border.
Now you have a beautiful rounded button that is ready to be used in your Flutter project.
Section 4: Adding Icons to Rounded Buttons
Adding an icon to a rounded button in Flutter is very easy. All we need to do is wrap our button’s child inside a Row widget and add the icon widget to it. Here are the steps:
– Add the following code to your Flutter project:
“`dart
RawMaterialButton(
onPressed: () {},
fillColor: Colors.blue,
splashColor: Colors.lightBlueAccent,
elevation: 5.0,
child: Row(
mainAxisSize: MainAxisSize.min,
children: [
Icon(Icons.add, color: Colors.white),
SizedBox(width: 5.0),
Text(
‘Button’,
style: TextStyle(color: Colors.white),
),
],
),
padding: EdgeInsets.symmetric(horizontal: 20.0, vertical: 10.0),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.blue)),
);
“`
– In the code above, we have added the Row widget to the child property of the RawMaterialButton. Inside the Row widget, we have added an Icon widget that displays the add icon from the material icons library. We have also added some padding between the icon and the text using SizedBox widget.
– We can customize the icon according to our needs by changing the icon property.
Now you have a rounded button with an icon in it.
Section 5: Customizing the Rounded Button’s Colors
To customize the colors of our Rounded button, we need to set the fillColor and splashColor properties of the RawMaterialButton widget. Here are the steps:
– Add the following code to your Flutter project:
“`dart
RawMaterialButton(
onPressed: () {},
fillColor: Colors.green,
splashColor: Colors.lightGreenAccent,
elevation: 5.0,
child: Text(
‘Button’,
style: TextStyle(color: Colors.white),
),
padding: EdgeInsets.symmetric(horizontal: 20.0, vertical: 10.0),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.greenAccent)),
);
“`
– In the code above, we have set the fillColor property to green and the splashColor property to lightGreenAccent. We have also added a green border to the button using the side property of the RoundedRectangleBorder widget.
Now you have a rounded button with customized colors. You can change the colors according to your project’s needs.
Section 6: Creating a Gradient Rounded Button
Creating a gradient rounded button in Flutter is straightforward. We need to use the Container widget to create the gradient effect. Here are the steps:
– Add the following code to your Flutter project:
“`dart
RawMaterialButton(
onPressed: () {},
elevation: 5.0,
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(18.0),
gradient: LinearGradient(colors: [
Colors.deepPurple,
Colors.purpleAccent,
]),
),
padding: EdgeInsets.symmetric(horizontal: 20.0, vertical: 10.0),
child: Text(
‘Button’,
style: TextStyle(color: Colors.white),
),
),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(18.0),
side: BorderSide(color: Colors.deepPurple)),
);
“`
– In the code above, we have wrapped the child of the RawMaterialButton widget inside a Container widget. We have set the decoration property of the Container widget to BoxDecoration, which allows us to add a gradient effect to the button.
– The borderRadius property is used to create a rounded border, while the LinearGradient widget is used to specify the gradient colors.
Now you have a gradient rounded button that looks amazing.
Section 7: Adding Animations to Rounded Buttons
Adding animations to rounded buttons can add a lot of flair to your Flutter project. One way to add animations to your buttons is by using the AnimatedContainer widget. Here are the steps:
– Add the following code to your Flutter project:
“`dart
class AnimatedButton extends StatefulWidget {
const AnimatedButton({Key? key}) : super(key: key);
@override
_AnimatedButtonState createState() => _AnimatedButtonState();
}
class _AnimatedButtonState extends State {
double _width = 200.0;
double _height = 50.0;
double _borderRadius = 18.0;
@override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
setState(() {
_width = _width == 200.0 ? 250.0 : 200.0;
_height = _height == 50.0 ? 70.0 : 50.0;
_borderRadius = _borderRadius == 18.0 ? 30.0 : 18.0;
});
},
child: AnimatedContainer(
duration: Duration(milliseconds: 500),
width: _width,
height: _height,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(_borderRadius),
color: Colors.blue,
),
child: Center(
child: Text(
‘Button’,
style: TextStyle(color: Colors.white),
),
),
),
);
}
}
“`
– In the code above, we have created a StatefulWidget called AnimatedButton. Inside the stateful widget, we have defined three variables – _width, _height, and _borderRadius, which will be used to create animation effects.
– We then wrapped the AnimatedContainer widget inside a GestureDetector widget to detect clicks on the button. The onTap() method changes the _width, _height, and _borderRadius variables, triggering a state rebuild that results in an animated button.
Now you have an animated rounded button that you can use in your Flutter project.
