Introducing a new and improved rating bar for Flutter, offering versatility and full customization.

Tap, drag and hover gestures are seamlessly supported, providing a smooth user experience.

- High degree of customization for the rating widgets, which can be of different sizes, shapes, and colors.
- Precise hit testing, as the child widget's render object is utilized to determine the results.
- Allows for filtering gestures with either
tapOnly
ortapAndDrag
options. - Rating reports on cursor hovering supported.
- Built on Flutter's
Wrap
widget, offering a variety of supported layouts, including consideration ofWrap
properties such astextDirection
andverticalDirection
when painting the indicators.
Getting started #
First import the widget
import 'package:flutter_pannable_rating_bar/flutter_pannable_rating_bar.dart';
Usage #
This widget is stateless and highly flexible, allowing you to easily manipulate values and
customize the display of the PannableRatingBar
. Simply rebuild the widget with the value provided
in the onChanged
callback or onHover
callback and the widget will automatically adjust the
rating distribution across each rating widget.

double rating = 0.0;
PannableRatingBar(
rate: rating,
items: List.generate(5, (index) =>
const RatingWidget(
selectedColor: Colors.yellow,
unSelectedColor: Colors.grey,
child: Icon(
Icons.star,
size: 48,
),
)),
onChanged: (value) { // the rating value is updated on tap or drag.
setState(() {
rating = value;
});
},
)
The widget also supports getting the rate value by hovering with the onHover
callback. It works
best on devices that support a mouse cursor, including desktop web browsers.
double rating = 0.0;
PannableRatingBar(
rate: rating,
items: List.generate(5, (index) =>
const RatingWidget(
selectedColor: Colors.yellow,
unSelectedColor: Colors.grey,
child: Icon(
Icons.star,
size: 48,
),
)),
onHover: (value) { // the rating value is updated every time the cursor moves over a new item.
setState(() {
rating = value;
});
},
)
Utilize your own custom widgets as the rating indicators. With complete customization freedom, they don't have to be uniform in size, color, or any other aspect.

This widget utilizes the layout capabilities of Flutter's built-in Wrap
widget, allowing for a wide
range of possible layouts to be achieved. The properties of the Wrap
widget, such as textDirection
and verticalDirection
, are also considered when painting the indicators, giving you even greater
control over the final look and feel of the rating bar.
