Customizing Scrollbar in Flutter
In Flutter, you can easily customize the default scrollbar using the ScrollbarTheme
widget. This allows you to adjust the color, thickness, and visibility of the scrollbar. Below is an example of how to customize the scrollbar.
Code Example
ScrollbarTheme(
data: ScrollbarThemeData(
thumbColor: MaterialStateProperty.all(Colors.grey[400]), // Color of the scrollbar
trackColor: MaterialStateProperty.all(Colors.white), // Color of the track
trackBorderColor: MaterialStateProperty.all(Colors.grey[300]), // Color of the track border
thickness: MaterialStateProperty.all(8.0), // Thickness of the scrollbar
thumbVisibility: MaterialStateProperty.all(true), // Visibility of the scrollbar
trackVisibility: MaterialStateProperty.all(true), // Visibility of the track
),
child: ListView.builder(
itemCount: records.length, // Number of list items
itemBuilder: (context, index) => _buildListItem(
records[index], index, tableWidth, records.length - 1 == index),
),
);
Explanation
The code above demonstrates how to customize the scrollbar in Flutter. By using the ScrollbarTheme
widget, you can set various properties of the scrollbar. The thumbColor
sets the color of the scrollbar, while trackColor
sets the color of the scrollbar track. The thickness
adjusts the thickness of the scrollbar, and thumbVisibility
and trackVisibility
control the visibility of the scrollbar and track, respectively.
