A device simulator to speed up development for different devices.

Approximates how an app looks and behaves on a device by simulating:

  • frame
  • notches, home indicators etc.
  • screen size and resolution
  • orientation
  • safe areas
  • keyboard insets
  • visual density
  • text styles
  • (and more)

Sample

Usage

  1. Wrap your app with the DeviceSim widget.
  2. Add useInheritedMediaQuery: true to your app. 
    DeviceSim(
  ...
  builder: (context) => MaterialApp(
    ...
    useInheritedMediaQuery: true,
    ...      
))
  3. Open your app as desktop or web app.

Custom Devices

Implement a new DeviceConfiguration:

const myDevice = DeviceConfiguration(
    name: 'My Device',
    frameConfiguration: FrameConfiguration(
      frameInsets: EdgeInsets.all(20.0),
      outerRadius: BorderRadius.all(Radius.circular(68)),
      innerRadius: BorderRadius.all(Radius.circular(48)),
      features: [
        StaticFeature(
            portraitAlignment: Alignment.topCenter,
            child: IPhone13Notch(
              width: 174.0,
              height: 38.0,
            )),
      ],
    ),
    screenConfiguration: ScreenConfiguration(
        standardRectangleDiagonalInInch: 5.42,
        size: Size(375.0, 812.0),
        portraitPadding: EdgeInsets.fromLTRB(0.0, 50.0, 0.0, 34.0),
        portraitViewPadding: EdgeInsets.fromLTRB(0.0, 50.0, 0.0, 34.0),
        portraitViewInsets: EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
        portraitPaddingIfKeyboard: EdgeInsets.fromLTRB(0.0, 50.0, 0.0, 0.0),
        portraitViewPaddingIfKeyboard: EdgeInsets.fromLTRB(0.0, 50.0, 0.0, 34.0),
        portraitViewInsetsIfKeyboard: EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 336.0),
        landscapePadding: EdgeInsets.fromLTRB(50.0, 0.0, 50.0, 21.0),
        landscapeViewPadding: EdgeInsets.fromLTRB(50.0, 0.0, 50.0, 21.0),
        landscapeViewInsets: EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
        landscapePaddingIfKeyboard: EdgeInsets.fromLTRB(50.0, 0.0, 50.0, 0.0),
        landscapeViewPaddingIfKeyboard: EdgeInsets.fromLTRB(50.0, 0.0, 50.0, 21.0),
        landscapeViewInsetsIfKeyboard: EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 209.0),
        textScaleFactor: 1.0,
        devicePixelRatio: 3.0,
        targetPlatform: TargetPlatform.iOS,
        features: [
          Align(
            alignment: Alignment.bottomCenter,
            child: HomeIndicator(
              widthInPortrait: 134.0,
              widthInLandscape: 210.0,
            ),
          ),
        ]));

CalibrationScreen helps to find the correct values for the ScreenConfiguration. Just open it on a real device or emulator and find the values by rotating the device and opening and closing the keyboard.

void main() {
  runApp(const MaterialApp(
    home: CalibrationScreen(),
  ));
}
