How to Change Mouse Hover Cursor in Flutter Web
Introduction
Changes in the cursor can significantly enhance user experience, especially in web applications. The default behavior of changing the mouse cursor when hovering over different widgets can be modified using Flutter. This guide explains how to change the mouse hover cursor in Flutter web, providing a step-by-step approach to achieve this functionality.
Understanding the Basics
To change the mouse hover cursor in Flutter web, you need to understand the basics of how Flutter handles cursor changes. The `MouseCursor` class is used to define different cursor types. By using this class, you can specify the type of cursor to be displayed when the mouse is hovered over a specific widget.
Changing the Cursor
To change the cursor when the mouse is hovered over a widget, you can use the `cursor` property provided by the `MouseRegion` widget. This property allows you to specify a `MouseCursor` that will be displayed when the mouse is within the bounds of the `MouseRegion`.
“`dart
import ‘package:flutter/material.dart’;
class HoverCursor extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MouseRegion(
cursor: SystemMouseCursors.wait, // Change the cursor to wait
child: Container(
width: 200,
height: 200,
color: Colors.blue,
child: Center(
child: Text(‘Hover over me’),
),
),
);
}
}
“`
Customizing the Cursor
If you want to use a custom cursor, you can do so by using the `SystemMouseCursors` class and specifying the type of cursor you want to use. For example, you can use `SystemMouseCursors.click` to display a clicking cursor when the mouse is hovered over a specific widget.
“`dart
class CustomCursor extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MouseRegion(
cursor: SystemMouseCursors.click, // Change the cursor to click
child: Container(
width: 200,
height: 200,
color: Colors.red,
child: Center(
child: Text(‘Custom cursor’),
),
),
);
}
}
“`
Conclusion
Changing the mouse hover cursor in Flutter web can be achieved by using the `MouseCursor` class and the `cursor` property provided by the `MouseRegion` widget. This allows you to specify different cursor types when the mouse is hovered over specific widgets, enhancing the overall user experience.
