Unable to capture width screenshot in Sony Xperia IV device

[Murmurl912]

Here is crash log:

ERROR 'package:screenshot/screenshot.dart': Failed assertion: line 155 pos 12: 'logicalSize.aspectRatio.toStringAsPrecision(5) ==
ERROR imageSize.aspectRatio
ERROR .toStringAsPrecision(5)': is not true.
ERROR #0 _AssertionError._doThrowNew (dart:core-patch/errors_patch.dart:51:61)
ERROR #1 _AssertionError._throwNew (dart:core-patch/errors_patch.dart:40:5)
ERROR #2 ScreenshotController.widgetToUiImage (package:screenshot/screenshot.dart:155:12)
ERROR #3 ScreenshotController.captureFromWidget (package:screenshot/screenshot.dart:102:28)

I am using screenshot 2.3.0.
The code used to capture screenshot is:

      final capture = await screenshotController.captureFromWidget(
          SomWidget(),
          context: context,
          pixelRatio: 1080 / 390.0 / 2);

The assert is thrown in line 153:

    final RenderRepaintBoundary repaintBoundary = RenderRepaintBoundary();
    final platformDispatcher = WidgetsBinding.instance.platformDispatcher;
    final fallBackView = platformDispatcher.views.first;
    final view =
        context == null ? fallBackView : View.maybeOf(context) ?? fallBackView;
    Size logicalSize =
        targetSize ?? view.physicalSize / view.devicePixelRatio; // Adapted
    Size imageSize = targetSize ?? view.physicalSize; // Adapted

    assert(logicalSize.aspectRatio.toStringAsPrecision(5) ==
        imageSize.aspectRatio
            .toStringAsPrecision(5)); // Adapted (toPrecision was not available)

logicalSize = Size(417.5, 975.2)
imageSize = Size(1096.0, 2560.0)

view.physicalSize = Size(1096.0, 2560.0)
view.devicePixelRatio = 2.625

logicalSize.aspectRatio = 0.42812500000000003
imageSize.aspectRatio = 0.428125

imageSize.aspectRatio.toStringAsPrecision(5) = 0.42812
logicalSize.aspectRatio.toStringAsPrecision(5) =  0.42813

Why the assertion in line 153 is needed, a small rounding error could fail it:

    assert(logicalSize.aspectRatio.toStringAsPrecision(5) ==
        imageSize.aspectRatio
            .toStringAsPrecision(5)); // Adapted (toPrecision was not available)
