How to implement code in dart file :
You need to implement it in your code respectively:
Create a new dart file called reviews_demo.dart inside the lib folder.
First, we will be creating an integer variable.
int selectedValue1;
We will add a variable on the void onChange1() method. In this method, we will add setState(). In this setState, we will add the selectedValue1 variable that is equal to the value.
void onChange1(int value) {
setState(() {
selectedValue1 = value;
});
}
In the body, we will add a column widget, and mainAxisAlignment was the center, and crossAxisAlignment was started. We will add a text and ReviewSlider(). In the ReviewSlider, we will add optionStyle means Text style of review titles like color, sizes, etc., and onChange means trigger whenever a pointer has changed the slider’s value and is no longer in contact with the screen. Also, we will add text selectedValue1.toString(). It will be displayed on the device.
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'How was the service you received?',
style: TextStyle(color: Colors.black,
fontSize: 18),
),
SizedBox(height: 20),
ReviewSlider(
optionStyle: TextStyle(
color: Colors.red,
fontWeight: FontWeight.bold,
),
onChange: onChange1,
),
Text(selectedValue1.toString(),style: TextStyle(color: Colors.red),
),
],
),
When we run the application, we ought to get the screen’s output like the underneath screen capture.
Now, we will add more than one slider with a different color of text style.
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'How was the service you received?',
style: TextStyle(color: Colors.black,
fontSize: 18),
),
SizedBox(height: 20),
ReviewSlider(
optionStyle: TextStyle(
color: Colors.red,
fontWeight: FontWeight.bold,
),
onChange: onChange1,
),
Text(selectedValue1.toString(),style: TextStyle(color: Colors.red),),
SizedBox(height: 20),
Text(
'Quality of our product?',
style: TextStyle(color: Colors.black, fontSize: 18),
),
SizedBox(height: 20),
ReviewSlider(
optionStyle: TextStyle(
color: Colors.orange,
fontWeight: FontWeight.bold,
),
onChange: onChange2,
initialValue: 1,
),
Text(selectedValue2.toString(),style: TextStyle(color: Colors.orange)),
SizedBox(height: 20),
Text(
'Price of our product?',
style: TextStyle(color: Colors.black, fontSize: 18),
),
SizedBox(height: 20),
ReviewSlider(
optionStyle: TextStyle(
color: Colors.black,
fontWeight: FontWeight.bold,
),
onChange: onChange3,
initialValue: 3,
),
Text(selectedValue3.toString(),style: TextStyle(color: Colors.black)),
],
),
We will add three reviews slider with different text colors and also different initialValue, and different titles. When we run the application, we ought to get the screen’s output like the underneath screen capture.
Code File:
import 'package:flutter/material.dart';
import 'package:reviews_slider/reviews_slider.dart';
class ReviewsDemo extends StatefulWidget {
@override
_ReviewsDemoState createState() => _ReviewsDemoState();
}
class _ReviewsDemoState extends State<ReviewsDemo> {
int selectedValue1;
int selectedValue2;
int selectedValue3;
void onChange1(int value) {
setState(() {
selectedValue1 = value;
});
}
void onChange2(int value) {
setState(() {
selectedValue2 = value;
});
}
void onChange3(int value) {
setState(() {
selectedValue3 = value;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.blueGrey[50],
appBar: AppBar(
backgroundColor: Colors.cyan,
title: Text("Flutter Reviews Slider Demo"),
automaticallyImplyLeading: false,
),
body: SafeArea(
child: Padding(
padding: const EdgeInsets.only(left:18.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
'How was the service you received?',
style: TextStyle(color: Colors.black,
fontSize: 18),
),
SizedBox(height: 20),
ReviewSlider(
optionStyle: TextStyle(
color: Colors.red,

onChange: onChange1,
),
Text(selectedValue1.toString(),style: TextStyle(color: Colors.red),),
SizedBox(height: 20),

),
SizedBox(height: 20),
ReviewSlider(
optionStyle: TextStyle(
