Image in Circle Shape Example – Using CircleAvatar

  • Align widget used to align the CircleAvatar to Center
  • By default, CircleAvatar radius size is 20. It’s okay for ListView item. For this example, I increased the size of radius to 50. you can delete that line and check.
  • NetworkImage shows the Image based on the given URL.

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter CircleAvatar Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text('CircleAvatar - NetworkImage Example'),
        ),
        body: Align(
          alignment: Alignment.topCenter,//aligns CircleAvatar to Top Center.
          child: CircleAvatar(
            radius: 50,//radius is 50
            backgroundImage: NetworkImage(
                'https://cdn.pixabay.com/photo/2015/03/03/20/42/man-657869_1280.jpg'),//image url
          ),
        ),
      ),
    );
  }
}


CircleAvatar Properties

1.backgroundColor: Use this property to fill the circle with color. If backgroundColor is not given, CircleAvatar uses a theme based color.

2.backgroundImage: Using backgroundImage property, You can set Image. Above example, uses NetworkImage. But you can also use FileImage, AssetImage, etc.

3.child: child property used set the widget inside the circle Avatar. Using this property, you can set Image, Icon or Text or any other Widget.

4.foregroundColor: It determines color of the text or Icon inside CircleAvatar.

5.foregroundImage: Foreground image of the CircleAvatar.

6.maxRadius: It determines maximum radius of the CircleAvatar.

7.minRadius: Decides the minimum radius of the CircleAvatar.

8.onBackgroundImageError: Callback released when background image loading fails.

9.onForegroundImageError: Callback executes when foreground Image loading fails.

10.radius: The size of the avatar (half of the diameter). Default size is 20 logical pixels.

Flutter CircleAvatar AssetImage Example

flutter circleavatar assetimage

  • In this example, Let’s use AssetImage widget and load image from app resources.

image in assets directory

  • First create an assets directory, and put your image in it. Just like above.

  assets:
    - assets/

  • Open the pubspec.yaml file, and add assets/ like above. Then only app can access Assets directory.
  • In dart code, you will use AssetImage and specify the path of the image.
  • Here Align used to align the Widget to topCenter. For an empty space around the CircleAvatar – Use Padding.

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter CircleAvatar Image Asset Example',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Circle Avatar AssetImage Example'),
        ),
        body: Align(
          alignment: Alignment.topCenter,//aligns to topCenter
          child: Padding(//gives empty space around the CircleAvatar
            padding: const EdgeInsets.all(8.0),
            child: CircleAvatar(
              radius: 35,//radius is 35.
              backgroundImage: AssetImage('assets/environment.jpg'),//AssetImage loads image URL.
            ),
          ),
        ),
      ),
    );
  }
}


Flutter Circle Avatar Text Example

CircleAvatar provides a property called child helps to set Text inside of it.

okay…Let’s do that.

  • Row widget : helps to horizontally align both CircleAvatar widgets.
  • SizedBox: gives empty space between CircleAvatar widgets.

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter CircleAvatar Text Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),

        ),
        body: Padding(
          padding: const EdgeInsets.all(8.0),
          child: Row(//aligns children to Center.
            mainAxisAlignment: MainAxisAlignment.center,
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
              CircleAvatar(
                child: Text(
                  'S',
                  style: TextStyle(
                    fontWeight: FontWeight.bold,
                    color: Colors.white,
                  ),
                ),
                backgroundColor: Colors.orange,
              ),
              SizedBox(
                width: 5.0,//empty space between CircleAvatar widgets.
              ),
              CircleAvatar(
                child: Text(
                  'Sun',
                  style: TextStyle(
                    fontWeight: FontWeight.bold,
                    color: Colors.white,
                  ),
                ),
                backgroundColor: Colors.red,
              ),
            ],
          ),
        ),
      ),
    );
  }
}
