The CupertinoActivityIndicator widget in Flutter is part of the Cupertino (iOS-style) library and is used to display an iOS-style activity indicator, commonly known as a spinner. It indicates that some operation is ongoing and provides a visual representation of progress.
Attributes:
animating (bool):
- Determines whether the activity indicator is currently running.
radius (double):
- The radius of the activity indicator. The default value is 11.0.
Example:
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
class CupertinoActivityIndicatorExample extends StatelessWidget {
@override
Widget build(BuildContext context) {
return CupertinoPageScaffold(
navigationBar: CupertinoNavigationBar(
middle: Text('CupertinoActivityIndicator Example'),
),
child: Center(
child: CupertinoActivityIndicator(),
),
);
}
}
void main() {
runApp(
MaterialApp(
home: CupertinoActivityIndicatorExample(),
),
);
}
In this example, a CupertinoActivityIndicator is displayed at the center of the screen within a CupertinoPageScaffold. The indicator will automatically start animating when the widget is rendered.
Customize the attributes like animating and radius based on your specific use case. The CupertinoActivityIndicator provides a clean and native-looking way to indicate ongoing activity in an iOS-style app.
