Anyone having this issue? It is now preventing me to release :(

Hi! Firstly, thank you for your awesome package

Problem

I am trying to get the Uint8List data from the DavinciCapture.click on the initState of an StatefulWidget like this:

WidgetsBinding.instance!.addPostFrameCallback((timeStamp) async {
      if (mounted && pictureKey.isNotNull) {
        
        pictureBytes = await DavinciCapture.click(
          pictureKey!,
          fileName: 'diven',
          returnImageUint8List: true,
          openFilePreview: false,
          saveToDevice: false,
        );

      }
    });

but pictureBytes is always null. Am I doing something wrong? Is it a bug?

class ShareModal extends StatefulWidget {
  const ShareModal({Key? key, required this.plan}) : super(key: key);

  final PlanDTO plan;

  @override
  _ShareModalState createState() => _ShareModalState();
}

class _ShareModalState extends State<ShareModal> with Utils, ShareableMixin {
  late final Future<Uri> uri;
  bool isLinkLoading = true;
  Uri? url;

  bool isScreenshotLoading = true;
  late Widget widgetPreview;
  // late final Future<dynamic> picture;
  Uint8List? pictureBytes;
  GlobalKey? pictureKey;

  @override
  void initState() {
    super.initState();

    uri = generatePlanLink(plan: widget.plan);
    uri.whenComplete(
      () async {
        if (mounted) {
          url = (await uri);
          setState(() {
            isLinkLoading = false;
          });
        }
      },
    );

    WidgetsBinding.instance!.addPostFrameCallback((_) async {

          openFilePreview: false,
          saveToDevice: false,

      }

              );
            },
          )
        else
          Center(
            child: ScaleOnTap(
              onTap: () => context.navigator.push(

              child: Hero(
                tag: 'planPreview',

Version

davinci: ^2.0.5

The image captured in the offStage method is not scrollable. Have to figure out a way for this.

Is it possible to use this package without storage permission.
Like just return uint8list without saving the image file into storage

This is My HomeScreen,

There is the More Button, Which Captures the ScreenShot. code

I can Easily with the Plugin Capture ScreenShot, But the Issue Coming is when I added the New Element the Plugin Captures the Screenshot of new element and when I add again a new element the plugin captures the screenshot the new one and forgets about the old. like this,

Error: No named parameter with the name 'window'.
window: ui.window,
^^^^^^
Flutter Version 3.10.0 Dart version 3.0.0
Breaking Changes: Window singleton is deprecated in preparation for multi-window support. Android Studio's Flamingo upgrade might cause some errors due to Java SDK and Gradle version mismatch.

The Plugin is very beautiful it removed my major issues and there is always big praise to its creators,
I always Believe in this kind of Humanful - Opensource. My Experience with this Opensource is very beautiful.
And I am also dedicated to helping grow this Plugin, Amen.

My Issue
When I am Capturing Something, it is giving a black border as outputs,
How can I fix these?

When offstage is used with these options. it works as expected, previews the image and saves a new file.

        openFilePreview: true,
        returnImageUint8List: false,
        saveToDevice: true

But I just want to save the file and not preview it. So when I turn openFilePreview=false. Not only is the preview gone. But the file isn't being saved. Expected behavior: No Preview and local saved file.

        openFilePreview: false,
        returnImageUint8List: true,
        saveToDevice: true

I even tired to get the Uint8List in return to manually save. But the object returned null.

        openFilePreview: false,
        returnImageUint8List: true,
        saveToDevice: false

It is only possible to choose between return uint8 list and open preview.
There is no way to just save the file.

I know that having the uint8list i can save the file. But i think it would be nice if the package did it.
The share package accepts a path for sharing files. I want to just share the image without previewing it.

for example when the app in Low resolution phone. Maybe we can use fixed size?

Unhandled Exception: type 'Null' is not a subtype of type 'Uint8List'

As the topic says, i got an error when running debug test in physic device(iphone XR , Ios 17)
but it works properly on both iphone 15 and iphone XR simulator (ios 17)

my code

static Future<void> update(context, Widget widget) async {
    Uint8List bytes = await DavinciCapture.offStage(widget,
        context: context,
        returnImageUint8List: true,
        wait: const Duration(seconds: 1),
        openFilePreview: true);
    final directory = await getApplicationSupportDirectory();
    File tempFile =
        File("${directory.path}/${DateTime.now().toIso8601String()}.png");
    await tempFile.writeAsBytes(bytes);

Appreciated for developed this awesome pkg.

The currently saved picture has color breaks

If the widget is outside the viewport, meaning the entire widget comes into view only if we have to scroll, Then this package fails.

This can be achieved by converting the entire widget into a canvas and then export it as image.

Check if the widget is in viewport, i.e key.currentContext.findRenderObject is not null or doesn't throw any exception

• If yes, use the existing method to export the widget into a image.
• If not, convert the widget to canvas then export it as image.

Add Null Safety

After my own implementation had the exact same problem I decided to switch to this package. Sadly, it has the exact same problem.

This happens whenn calling as follows:

Future<dynamic> image = DavinciCapture.offStage(
    widget,
    logicalSize: logicalSize,
    imageSize: imageSize,
    openFilePreview: false,
    fileName: fileName,
    returnImageUint8List: true,
  );

(await image) // <- Error
