At first create a database which contains order data and specially the status.
-- Create the database
CREATE DATABASE orders_db;
-- Use the newly created database
USE orders_db;
-- Create the orders table
CREATE TABLE orders (
id INT PRIMARY KEY,
chk_bill_name VARCHAR(255),
chk_bill_phone VARCHAR(20),
chk_bill_email VARCHAR(255),
chk_bill_country VARCHAR(100),
chk_bill_state VARCHAR(100),
chk_bill_city VARCHAR(100),
chk_bill_zip VARCHAR(10),
chk_bill_street_addr VARCHAR(255),
chk_product_ids VARCHAR(255),
chk_product_name VARCHAR(255),
chk_net DECIMAL(10, 2),
chk_date DATETIME,
chk_status VARCHAR(50),
chk_payment_mode VARCHAR(50),
chk_type VARCHAR(50),
chk_payment_status VARCHAR(50),
chk_request TEXT
);
Create The Empty Flutter Screen Called OrderPieChart
import 'package:flutter/cupertino.dart';
class OrderPieChart extends StatefulWidget {
const OrderPieChart({super.key});
@override
State<OrderPieChart> createState() => _OrderPieChartState();
}
class _OrderPieChartState extends State<OrderPieChart> {
@override
Widget build(BuildContext context) {
return const Placeholder();
}
}
Install Necessary Packages in pubscpec.yaml
pie_chart: ^5.4.0
Import Dependencies in OrderPieChart Screen
import 'package:pie_chart/pie_chart.dart';
import 'package:flutter/cupertino.dart';
class OrderPieChart extends StatefulWidget {
const OrderPieChart({super.key});
@override
State<OrderPieChart> createState() => _OrderPieChartState();
}
class _OrderPieChartState extends State<OrderPieChart> {
@override
Widget build(BuildContext context) {
return const Placeholder();
}
}
Import Other Dependencies
import 'package:flutter/cupertino.dart';
import 'package:shared_preferences/shared_preferences.dart';
import 'dart:convert';
import 'package:http/http.dart' as http;
import 'dart:async';
Create The Variables
String id = "";
String userName = "";
String status = "";
String phone = "";
String userMobile = '';
String userStudent = '';
List<dynamic> _userData = [];
bool _isLoading = true;
bool _hasError = false;
//Required For Pie Chart
Map<String, double> dataMap = {
"Success": 0,
"Pending": 0,
"Cancelled": 0,
};
Create Function to get User Details From The Shared Preferences
Future<void> _getUserInfo() async {
try {
SharedPreferences prefs = await SharedPreferences.getInstance();
String usermobile = prefs.getString('userMobile') ?? ''; // Get user mobile
String userNameValue = prefs.getString('userName') ?? ''; // Get user name
if (usermobile.isEmpty) {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Login(),
),
);
} else {
setState(() {
userMobile = usermobile;
userName = userNameValue; // Update userName
});
}
} catch (error) {
print('Error retrieving user info: $error');
}
}
Initiate _getUserInfo for default loading
@override
void initState() {
super.initState();
_getUserInfo();
}
Create _checkout function to check order details
Future<void> _checkOut() async {
final String apiUrl = 'https://indiawebdesigns.in/corporate-admin/controllers/Flutter/check_recordings.php?id=$userMobile';
try {
final response = await http.get(Uri.parse(apiUrl));
if (response.statusCode == 200) {
final List<dynamic> data = json.decode(response.body);
setState(() {
_userData = data;
_isLoading = false;
});
_updateDataMap(data);
} else {
throw Exception('Failed to load data');
}
} catch (error) {
setState(() {
_hasError = true;
_isLoading = false;
});
}
}
Now call _checkOut function once the _getUserInfo function is loaded up
Future<void> _getUserInfo() async {
try {
SharedPreferences prefs = await SharedPreferences.getInstance();
String usermobile = prefs.getString('userMobile') ?? ''; // Get user mobile
String userNameValue = prefs.getString('userName') ?? ''; // Get user name
if (usermobile.isEmpty) {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => Login(),
),
);
} else {
setState(() {
userMobile = usermobile;
userName = userNameValue; // Update userName
});
_checkOut();
}
} catch (error) {
print('Error retrieving user info: $error');
}
}
PHP Api code of fetching data using PHP
<?php
ob_start();
include('../../database.php');
header("Access-Control-Allow-Origin: *");
DB::connect();
$id = $_GET['id'];
$select_master_user = "SELECT * FROM `checkout` where chk_bill_phone = '$id' and chk_type = 'Learn' order by id desc";
$sql999 = $dbconn->prepare($select_master_user);
$sql999->execute();
$wlvd999 = $sql999->fetchAll(PDO::FETCH_ASSOC);
// Convert all values to strings
foreach ($wlvd999 as &$item) {
foreach ($item as &$value) {
$value = (string)$value;
}
}
$json = json_encode($wlvd999, JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT);
header('Content-Type: application/json; charset=utf-8');
echo str_replace('\\/', '/', $json);
Update The Dynamic List
void _updateDataMap(List<dynamic> data) {
Map<String, double> updatedDataMap = {
"Success": 0,
"Pending": 0,
"Cancelled": 0,
};
for (var item in data) {
String paymentStatus = item['chk_payment_status'];
if (updatedDataMap.containsKey(paymentStatus)) {
updatedDataMap[paymentStatus] = (updatedDataMap[paymentStatus] ?? 0) + 1;
} else {
updatedDataMap[paymentStatus] = 1;
}
}
setState(() {
dataMap = updatedDataMap;
});
}
Design the UI
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Row(
children: [
Text('Hi ', style: TextStyle(color: Colors.white)),
Text(userName, style: TextStyle(color: Colors.white)),
],
),
backgroundColor: Colors.black,
iconTheme: IconThemeData(color: Colors.white),
),
body: SingleChildScrollView(
child: Column(
children: [
SizedBox(height: 30,),
PieChart(
dataMap: dataMap,
animationDuration: Duration(milliseconds: 800),
chartLegendSpacing: 32,
chartRadius: MediaQuery.of(context).size.width / 2.7,
colorList: [Colors.green, Colors.orange, Colors.red],
initialAngleInDegree: 0,
chartType: ChartType.ring,
ringStrokeWidth: 32,
centerText: "Orders",
legendOptions: LegendOptions(
showLegendsInRow: false,
legendPosition: LegendPosition.right,
showLegends: true,
legendShape: BoxShape.circle,
legendTextStyle: TextStyle(
fontWeight: FontWeight.bold,
),
),
chartValuesOptions: ChartValuesOptions(
showChartValueBackground: true,
showChartValues: true,
showChartValuesInPercentage: true,
showChartValuesOutside: false,
decimalPlaces: 1,
),
),
],
),
),
);
}
