phone_info

Phone Info

A Flutter plugin for retrieving detailed phone information on Android devices, including network status, device details, battery information, sensors, and comprehensive system specifications. This plugin provides a flexible API to fetch all information at once or individual pieces as needed, making it ideal for apps requiring device or network insights.

Features

• Network Information:
  • Check if the device is connected to a network (isConnected).
  • Get the connection type (Wi-Fi, Mobile Data, or None).
  • Retrieve the network operator name (e.g., "Robi").
  • Get Wi-Fi signal strength in RSSI (dBm).
  • Access detailed network data (local IP, DNS, network type).
• Device Information:
  • Device name (e.g., "realme C61").
  • Manufacturer (e.g., "realme").
  • Model (e.g., "RMX3930").
  • Operating system version (e.g., "14").
  • Architecture (e.g., "aarch64").
  • Unique device ID.
  • Total memory (RAM) in MB.
  • Available storage in MB.
• Battery Information:
  • Battery level percentage.
  • Charging status.
  • Battery health.
  • Temperature.
  • Real-time battery status updates via event streams.
• Hardware Information:
  • CPU details (core count, frequency, load average).
  • Screen specifications (resolution, density, refresh rate, HDR support).
  • Sensor list with detailed information.
  • Storage details (internal and external).
  • Camera specifications.
  • Biometric capabilities.
• System Information:
  • SIM card details.
  • System health metrics.
  • Accessibility services.
  • Security information (root detection, encryption status).
  • App usage statistics.
• Flexible API: Fetch all information in a single call or retrieve individual pieces as needed.
• Error Handling: Gracefully handles permission denials and unavailable data.

Usage

Basic Example

Below is a simple Flutter app demonstrating how to use the plugin to fetch phone information:

import 'package:flutter/material.dart';
import 'package:phone_info/phone_info.dart';
import 'package:permission_handler/permission_handler.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: const PhoneInfoScreen(),
    );
  }
}

class PhoneInfoScreen extends StatefulWidget {
  const PhoneInfoScreen({super.key});

  @override
  _PhoneInfoScreenState createState() => _PhoneInfoScreenState();
}

class _PhoneInfoScreenState extends State<PhoneInfoScreen> {
  String _output = 'Press a button to fetch info';

  Future<void> _requestPermissions() async {
    await Permission.phone.request();
  }

  @override
  void initState() {
    super.initState();
    _requestPermissions();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Phone Info Plugin')),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.stretch,
          children: [
            Text(_output, style: const TextStyle(fontSize: 16)),
            const SizedBox(height: 16),
            ElevatedButton(
              onPressed: () async {
                try {
                  final info = await PhoneInfoPlugin.getPhoneInfo();
                  setState(() {
                    _output = 'All Info: $info';
                  });
                } catch (e) {
                  setState(() {
                    _output = 'Error: $e';
                  });
                }
              },
              child: const Text('Get All Phone Info'),
            ),
            ElevatedButton(
              onPressed: () async {
                try {
                  final deviceName = await PhoneInfoPlugin.getDeviceName();
                  setState(() {
                    _output = 'Device Name: $deviceName';
                  });
                } catch (e) {
                  setState(() {
                    _output = 'Error: $e';
                  });
                }
              },
              child: const Text('Get Device Name'),
            ),
            ElevatedButton(
              onPressed: () async {
                try {
                  final batteryInfo = await PhoneInfoPlugin.getBatteryInfo();
                  setState(() {
                    _output = 'Battery Info: $batteryInfo';
                  });
                } catch (e) {
                  setState(() {
                    _output = 'Error: $e';
                  });
                }
              },
              child: const Text('Get Battery Info'),
            ),
          ],
        ),
      ),
    );
  }
}

Streaming Battery Updates

The plugin also supports streaming real-time battery updates:

import 'package:flutter/material.dart';
import 'package:phone_info/phone_info.dart';

class BatteryMonitorScreen extends StatefulWidget {
  const BatteryMonitorScreen({super.key});

  @override
  _BatteryMonitorScreenState createState() => _BatteryMonitorScreenState();
}

class _BatteryMonitorScreenState extends State<BatteryMonitorScreen> {
  Map<String, dynamic>? _batteryInfo;
  late Stream<Map<String, dynamic>> _batteryStream;

  @override
  void initState() {
    super.initState();
    _batteryStream = PhoneInfoPlugin.batteryInfoStream();
    _batteryStream.listen((batteryInfo) {
      setState(() {
        _batteryInfo = batteryInfo;
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Battery Monitor')),
      body: Center(
        child: _batteryInfo == null
            ? const CircularProgressIndicator()
            : Column(
                mainAxisAlignment: MainAxisAlignment.center,
                children: [
                  Text('Battery Level: ${_batteryInfo!['batteryLevel']}%'),
                  Text('Status: ${_batteryInfo!['isCharging'] ? 'Charging' : 'Not Charging'}'),
                  Text('Health: ${_batteryInfo!['health']}'),
                  Text('Temperature: ${_batteryInfo!['temperature']}°C'),
                ],
              ),
      ),
    );
  }
}

Notes

• All methods are asynchronous and return Futures. Use await to get the result ( e.g., await PhoneInfoPlugin.getDeviceName()).
• Methods that may fail due to permissions (e.g., getNetworkOperator) return null if the data is unavailable.
• Wrap method calls in try-catch blocks to handle potential platform exceptions.

Permissions

The plugin requires the following Android permissions:

Permission	Purpose	Runtime Permission Required?
ACCESS_WIFI_STATE	Access Wi-Fi signal strength	No
ACCESS_NETWORK_STATE	Check network connection status	No
READ_PHONE_STATE	Get network operator name	Yes (Android 6.0+)
PACKAGE_USAGE_STATS	Get app usage statistics	Yes (special approval)

Requesting Runtime Permissions

Use the permission_handler package to request permissions at runtime:

import 'package:permission_handler/permission_handler.dart';

Future<void> requestPermissions() async {
  if (await Permission.phone.request().isGranted) {
    // Permission granted
  } else {
    // Handle permission denial
  }
  
  // For app usage stats (special permission)
  if (await Permission.systemAppInfo.request().isGranted) {
    // Permission granted
  } else {
    // Direct user to settings
    await openAppSettings();
  }
}

Troubleshooting

• MissingPluginException: If you see No implementation found for method ..., ensure the plugin is properly built:
  • Run flutter clean and flutter pub get in both the plugin and app directories.
  • Rebuild the app with flutter run.
• Instance of 'Future<String?>': Ensure you use await when calling asynchronous methods ( e.g., await PhoneInfoPlugin.getDeviceName()).
• Null Values: If methods like getNetworkOperator return null, check that the required permissions are granted.
• Build Failures: Ensure your android/build.gradle includes androidx.core:core-ktx:1.12.0 and the correct Kotlin version (e.g., 1.8.22 or later).
• App Usage Stats Not Working: This requires special permission. Guide users to enable it in settings:

  // Check if permission is granted
  if (!(await Permission.systemAppInfo.isGranted)) {
    // Open settings
    await openAppSettings();
  }
