appcare_flutter

An all-in-one, enterprise-grade Flutter utility package for app maintenance, auto-upgrader UI, hardware diagnostics, security anti-cheat checks, system controls, and native launchers — using RAW CODE ONLY.

Zero External Dependencies on the Dart/Flutter side. Pure performance using native Platform Channels and platform SDKs.

🌟 Key Highlights

  • 🚀 Zero External Dependencies: Lightweight and eliminates conflict with third-party packages.

  • 🛡️ Built-in Security & Anti-Cheat: Screenshot blocking, Fake GPS mock location detection, network auto-time verification, and screen recording detection.
  • 🔊 System & Hardware Controls: Native flashlight, volume control, silent mode, app icon badging, biometrics check, and system audio beeps.
  • 🌐 Network & Diagnostics: Server ping latency (ms), local IP discovery, Wi-Fi signal strength, battery status, disk storage space, and thermal diagnostics.

📋 Comprehensive Feature Overview & Code Examples

1. 🌟 In-App Rating & Review

Prompt users for store reviews with built-in cooldown logic to prevent spamming.

final appCare = AppCare();

// Request review (prompts only if minDaysBeforePrompt interval has passed)
bool prompted = await appCare.requestReview(minDaysBeforePrompt: 7);

// Reset prompt cooldown history
await appCare.resetReviewHistory();

2. 🆙 Automatic Upgrader UI Widgets

Drop-in replacement for the upgrader package. Automatically prompts users when a new version is released.

// Wrap your root app with UpgradeAlert
void main() {
  runApp(
    const UpgradeAlert(
      child: MyApp(),
    ),
  );
}

// Or embed an UpgradeCard in Settings / Profile screens
const UpgradeCard(
  elevation: 3,
  title: 'New Update Available!',
)

3. 🔦 Flashlight / Torch Controller

Direct camera flashlight control without external packages.

await appCare.turnFlashlightOn();
await appCare.turnFlashlightOff();
await appCare.toggleFlashlight();

4. 🛡️ Security & Anti-Cheat Helpers

Protect your application from fake GPS, time tampering, screenshot leaks, and unauthorized screen recording.

// Check if user is using Fake GPS / Mock Location
bool isMock = await appCare.isMockLocation();

// Check if device time is automatically synced with network
bool isAutoTime = await appCare.isAutomaticTime();

// Check if app screen is currently being recorded or cast
bool isRecording = await appCare.isScreenBeingRecorded();

// Enable screenshot & screen recording block on sensitive screens
await appCare.setScreenSecurity(enable: true);

5. 🔊 System Volume & Silent Mode

Read/set system media volume and check for ringer silent mode.

double currentVol = await appCare.getVolume(); // 0.0 to 1.0
await appCare.setVolume(0.7); // 70% volume
bool isMuted = await appCare.isMuted();

6. 📡 Network Diagnostics & Ping Latency

Measure actual server ping response latency, inspect Wi-Fi signal strength, and retrieve local IP address.

// Ping server in ms (e.g. 15ms)
int latencyMs = await appCare.pingHost(host: '8.8.8.8');

// Get local IPv4 address
String? localIp = await appCare.getLocalIpAddress();

// Get Wi-Fi signal strength (0 to 4 bars)
int signalStrength = await appCare.getWifiSignalStrength();

// Check active internet connection
bool isOnline = await appCare.checkConnectivity();

// Detailed network type (wifi, cellular, ethernet, none)
NetworkType netType = await appCare.getNetworkType();

7. 🔐 Biometrics Hardware & App Icon Badge

Check fingerprint / FaceID enrollment and set unread badge counts on the app icon.

// Biometrics hardware availability
bool canAuth = await appCare.canAuthenticateBiometrics();

// Set app icon unread badge count
await appCare.setAppBadgeCount(5);
await appCare.clearAppBadge();

8. 🔍 System Accessibility Font Scale & Beep

Read user font scale factor for responsive layouts and trigger native system audio feedback.

double fontScale = await appCare.getFontScale(); // e.g., 1.0 or 1.5
await appCare.playSystemBeep();

9. 📲 External App Presence Check

Verify if specific apps are installed on the device before attempting to launch them.

bool hasWhatsApp = await appCare.isAppInstalled('com.whatsapp');

10. 🌐 Native App & URL Launchers

Launch URLs, emails, and phone dialer directly without requiring url_launcher.

await appCare.openUrl('https://www.rahulreza.com');
await appCare.openEmail('your-email@gmial.com', subject: 'Inquiry');
await appCare.openDialer('+8800000000000');

11. 💡 Keep Screen Awake (WakeLock)

Keep device screen turned on during video playback or reading screens.

await appCare.setKeepScreenOn(keepOn: true);

12. 📳 Haptic Vibration Engine

Trigger tactile feedback across multiple intensity presets.

await appCare.vibrate(type: HapticType.light);
await appCare.vibrate(type: HapticType.medium);
await appCare.vibrate(type: HapticType.heavy);
await appCare.vibrate(type: HapticType.success);
await appCare.vibrate(type: HapticType.error);

13. 📋 Clipboard & Screen Orientation Controls

Copy and read system clipboard text, and lock screen orientation.

await appCare.copyToClipboard('Hello World!');
String? text = await appCare.getTextFromClipboard();

await appCare.setOrientation(ScreenOrientation.portrait);
await appCare.setOrientation(ScreenOrientation.landscape);
await appCare.setOrientation(ScreenOrientation.unlock);

14. 🌡️ Thermal & RAM Diagnostics

Monitor RAM memory pressure and thermal overheating status.

bool lowRam = await appCare.isLowMemory();
ThermalStatus thermal = await appCare.getThermalStatus();

15. 🔋 Battery & Disk Storage Info

Retrieve battery level percentage, charging state, low power mode, and free/total storage capacity.

BatteryInfo battery = await appCare.getBatteryInfo();
print('Battery: ${battery.batteryLevel}% (Charging: ${battery.isCharging})');

StorageInfo storage = await appCare.getStorageInfo();
print('Free storage: ${storage.freeGB.toStringAsFixed(2)} GB / ${storage.totalGB.toStringAsFixed(2)} GB');
