Usage #

Basic Usage #

Wrap your MaterialApp with DeviceWrapper for web preview:

import 'package:flutter/foundation.dart' show kIsWeb;
import 'package:device_wrapper/device_wrapper.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final materialApp = MaterialApp(
      home: MyHomePage(),
    );

    // Only use DeviceWrapper on web
    if (kIsWeb) {
      return DeviceWrapper(
        initialMode: DeviceMode.mobile,
        showModeToggle: true,
        child: materialApp,
      );
    }

    return materialApp;
  }
}

With Mode Change Callback #

DeviceWrapper(
  initialMode: DeviceMode.mobile,
  showModeToggle: true,
  onModeChanged: (mode) {
    print('Device mode changed to: ${mode.displayName}');
  },
  child: MyApp(),
)

Custom Device Configuration #

DeviceWrapper(
  initialMode: DeviceMode.mobile,
  mobileConfig: DeviceConfig(
    width: 375,
    height: 812,
    borderRadius: 44.0,
    borderWidth: 5.0,
    borderColor: Colors.black,
    showNotch: true,
    showHomeIndicator: true,
  ),
  tabletConfig: DeviceConfig(
    width: 834,
    height: 1194,
    borderRadius: 20.0,
    borderWidth: 6.0,
    showNotch: false,
    showHomeIndicator: true,
  ),
  child: MyApp(),
)

Custom Background Color #

DeviceWrapper(
  backgroundColor: const Color(0xFF0D1117), // GitHub dark theme
  child: MyApp(),
)

Disable Wrapper (for production) #

DeviceWrapper(
  enabled: false, // Renders child directly without wrapper
  child: MyApp(),
)

Mobile Device Behavior #

Control how the wrapper behaves when running on a real mobile device (iOS/Android):

// Default: Show toggle button on mobile devices
DeviceWrapper(
  mobileDeviceBehavior: MobileDeviceBehavior.showToggle,
  child: MyApp(),
)

// Always show device frame even on mobile
DeviceWrapper(
  mobileDeviceBehavior: MobileDeviceBehavior.alwaysShowFrame,
  child: MyApp(),
)

// Always hide frame on mobile (render child directly)
DeviceWrapper(
  mobileDeviceBehavior: MobileDeviceBehavior.alwaysHideFrame,
  child: MyApp(),
)

API Reference #

DeviceWrapper #

DeviceMode #

enum DeviceMode {
  mobile,  // iPhone 16 Pro (393×852)
  tablet,  // iPad Pro 11" (834×1194)
}

MobileDeviceBehavior #

enum MobileDeviceBehavior {
  alwaysShowFrame,  // Always show the device frame wrapper
  alwaysHideFrame,  // Always render child directly without frame
  showToggle,       // Show a toggle to let user choose (default)
}

DeviceConfig #

Default Device Configurations #

Mobile - iPhone 16 Pro (393×852) #

• Physical resolution: 1179×2556 @ 3x scale
• Border radius: 55px (rounded corners)
• Border width: 12px (titanium bezel)
• Dynamic Island with camera lens effect
• Home indicator bar

• Physical resolution: 1668×2388 @ 2x scale
• Border radius: 18px
• Border width: 14px
• Home indicator only (no notch)

Auto-Scaling Behavior #

The device frame automatically scales to fit within the available browser/window size:

• Scales down when window is smaller than device dimensions
• Never scales up beyond original size (max scale = 1.0)
• Maintains aspect ratio - device is never distorted
• Responsive - automatically adjusts when resizing browser window
• Minimum scale: 0.3 (to ensure content remains visible)

Example #

Check out the example folder for a complete demo application:

cd example
flutter run -d chrome

Use Cases #

• Web Development: Preview mobile/tablet layouts when developing on web
• Client Demos: Show clients how the app looks on different devices
• Screenshot Generation: Capture consistent device-framed screenshots
• Responsive Testing: Quickly switch between device sizes during development
• Documentation: Create device mockups for documentation
