Learn how to implement widgets in Flutter to create a Personal Profile App, including profile pictures, text, icons, and buttons, with practical examples and code snippets.
In this section, we will delve into the practical implementation of widgets to create a Personal Profile App using Flutter. This hands-on project will guide you through adding a profile picture, displaying user information, incorporating contact icons, and implementing an action button. By the end of this section, you’ll have a cohesive and visually appealing user interface that you can further customize and expand upon.
The profile picture is often the focal point of a personal profile app. In Flutter, the CircleAvatar
widget is a perfect choice for displaying circular images, which are commonly used for profile pictures.
CircleAvatar
with Local AssetsTo display a profile picture from local assets, you can use the CircleAvatar
widget with the AssetImage
class. Here’s a simple example:
CircleAvatar(
radius: 50,
backgroundImage: AssetImage('assets/images/profile.jpg'),
);
radius
property defines the size of the circle, while backgroundImage
specifies the image source. Ensure that the image path is correctly set in your pubspec.yaml
file under the assets
section.CircleAvatar
with Network ImagesIf your profile picture is hosted online, you can use the NetworkImage
class:
CircleAvatar(
radius: 50,
backgroundImage: NetworkImage('https://example.com/profile.jpg'),
);
Next, we’ll add text widgets to display the user’s name and a short bio. The Text
widget in Flutter is versatile and allows for extensive customization through the TextStyle
class.
Text(
'John Doe',
style: TextStyle(fontSize: 24, fontWeight: FontWeight.bold),
),
SizedBox(height: 10),
Text(
'A passionate Flutter developer.',
style: TextStyle(fontSize: 16, color: Colors.grey),
),
TextStyle
class is used to customize the font size, weight, and color. The SizedBox
widget adds vertical spacing between the name and bio.Contact icons provide a way for users to interact with the profile, such as sending an email or making a phone call. We’ll use a Row
widget to arrange Icon
widgets horizontally.
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.email, color: Colors.blue),
SizedBox(width: 10),
Icon(Icons.phone, color: Colors.green),
],
);
mainAxisAlignment
property centers the icons within the row. The SizedBox
widget adds horizontal spacing between icons.To make the icons interactive, wrap them with IconButton
or GestureDetector
:
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
IconButton(
icon: Icon(Icons.email, color: Colors.blue),
onPressed: () {
// Handle email tap
},
),
IconButton(
icon: Icon(Icons.phone, color: Colors.green),
onPressed: () {
// Handle phone tap
},
),
],
);
onPressed
callback is used to define actions when the icons are tapped.An action button is essential for performing primary actions, such as editing the profile. The ElevatedButton
widget is commonly used for this purpose.
ElevatedButton(
onPressed: () {
// Navigate to edit profile screen
},
child: Text('Edit Profile'),
);
onPressed
callback is where you define the action to be taken when the button is pressed.Customize the button’s appearance using the style
property:
ElevatedButton(
onPressed: () {},
style: ElevatedButton.styleFrom(
primary: Colors.teal,
padding: EdgeInsets.symmetric(horizontal: 30, vertical: 15),
textStyle: TextStyle(fontSize: 16, fontWeight: FontWeight.bold),
),
child: Text('Edit Profile'),
);
styleFrom
method allows you to customize the button’s color, padding, and text style.Now that we’ve explored individual widgets, let’s integrate them into a cohesive layout using a Column
widget. This will stack the widgets vertically, creating a structured and visually appealing profile page.
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
CircleAvatar(
radius: 50,
backgroundImage: AssetImage('assets/images/profile.jpg'),
),
SizedBox(height: 20),
Text(
'John Doe',
style: TextStyle(fontSize: 24, fontWeight: FontWeight.bold),
),
SizedBox(height: 10),
Text(
'A passionate Flutter developer.',
style: TextStyle(fontSize: 16, color: Colors.grey),
),
SizedBox(height: 20),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
IconButton(
icon: Icon(Icons.email, color: Colors.blue),
onPressed: () {
// Handle email tap
},
),
SizedBox(width: 10),
IconButton(
icon: Icon(Icons.phone, color: Colors.green),
onPressed: () {
// Handle phone tap
},
),
],
),
SizedBox(height: 30),
ElevatedButton(
onPressed: () {
// Navigate to edit profile screen
},
style: ElevatedButton.styleFrom(
primary: Colors.teal,
padding: EdgeInsets.symmetric(horizontal: 30, vertical: 15),
textStyle: TextStyle(fontSize: 16, fontWeight: FontWeight.bold),
),
child: Text('Edit Profile'),
),
],
);
Column
widget organizes the profile picture, text, icons, and button into a single vertical layout. The use of SizedBox
widgets ensures proper spacing between elements.To better understand the structure and flow of the widget implementation, refer to the following Mermaid.js diagram:
