System

Overview#

The System API covers system-level concerns — platform detection and opening the app's settings screen.

It's a core built-in: the facade resolves with nothing to install or register.

use Native\Mobile\Facades\System;

Platform detection#

System::isIos();      // true on iOS
System::isAndroid();  // true on Android
System::isMobile();   // true on either platform

Use these to branch behavior or conditionally render UI for a specific platform.

Each is also available as a global helper function — isIos(), isAndroid(), isMobile() — for terse use in Blade and components:

if (isAndroid()) {
    // ...
}

In Blade, the same checks are available as conditional directives:

@ios
    {{-- iOS-only markup --}}
@endios
 
@android
    {{-- Android-only markup --}}
@endandroid
 
@mobile
    {{-- running inside the native app (iOS or Android) --}}
@endmobile
 
@web
    {{-- running in a browser / outside the native app --}}
@endweb

Each also supports the usual @else… and @unless… forms — @elseios, @unlessandroid, and so on.

App settings#

Open the app's page in the device Settings app — useful for sending a user to re-grant a permission they previously denied:

System::appSettings();

Appearance (light / dark)#

Reading the current appearance and reacting to theme changes lives with the rest of theming — see Theming → Appearance in PHP for System::appearance(), isDarkMode(), isLightMode(), the isDark() / theme() helpers, and the AppearanceChanged event.
