PlatformException (PlatformException(Share callback error, prior share-sheet did not call back, did you await it

问题

在我的情况下,使用以下代码出现以下错误:当使用以下代码时出现PlatformException (PlatformException(分享回调错误,之前的分享表格没有回调,你是否等待它

final XFile file = XFile(path);
await Share.shareXFiles(,

但如果我像下面这样使用已弃用的方法(传递List),分享图片就可以正常工作:

await Share.shareFiles([path],
subject: subject,
text: text,
sharePositionOrigin: box.localToGlobal(Offset.zero) & box.size);

尽管shareFiles被标记为已弃用,但它仍然可以正常工作,而遵循文档并使用shareXFiles会引发平台异常错误:

我的环境:

Flutter 3.7.10 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 4b12645012(9天前) • 2023年4月3日 17:46:48 -0700

工具 • Dart 2.19.6 • DevTools 2.20.1

英文:

In my case am getting the following error: PlatformException (PlatformException(Share callback error, prior share-sheet did not call back, did you await it when using below code:

final XFile file = XFile(path);
await Share.shareXFiles(,

but if I use the deprecated method like below (passing the List), the sharing of image works perfectly:

await Share.shareFiles([path],
subject: subject,
text: text,
sharePositionOrigin: box.localToGlobal(Offset.zero) & box.size);

shareFiles is marked as deprecated but works fine, while following documentation and using shareXFiles, throws the plaform exception error:

步骤 1
在Android Studio中,转到:文件 -> 使缓存失效 -> 全部标记并重新启动。
PlatformException (PlatformException(Share callback error, prior share-sheet did not call back, did you await it

步骤 2

share_plus: ^7.1.0 现在可以分享 xFile。

从 URL(网络)分享图像

final dir = await getTemporaryDirectory();
final Response response = await Dio().get(
  selected,
  options: Options(
    responseType: ResponseType.bytes,
  ),
);
final file = File("${dir.path}/Image.png"); // 导入 'dart:io';
file.writeAsBytesSync(Uint8List.fromList(response.data));
debugPrint('==》 ${file.path}');

// 分享  
await Share.shareXFiles(
  [XFile(file.path)],
);

从 assert/local 分享

onPressed: () async {
  final dir = await getTemporaryDirectory();
  final byte = (await rootBundle.load("assets/images/download.png")).buffer.asUint8List(); // 转换成 Uint8List
  debugPrint('byte $byte');
  final file = File("${dir.path}/Image.png") ; // 导入 'dart:io';
  await file.writeAsBytes(byte);
  // 分享
  await Share.shareXFiles(
    [XFile(file.path)],
  );
},
英文:

Step 1
in Android studio goto : File -> Invalidate Caches -> mark all and restart.
PlatformException (PlatformException(Share callback error, prior share-sheet did not call back, did you await it

Step 2

share_plus: ^7.1.0 now share xFile.

Share image from Url (Network)

              final dir = await getTemporaryDirectory();
                final Response response = await Dio().get(
                  selected,
                  options: Options(
                    responseType: ResponseType.bytes,
                  ),
                );
                final file = File("${dir.path}/Image.png"); // import 'dart:io';
                 file.writeAsBytesSync(Uint8List.fromList(response.data));
                 debugPrint('==> ${file.path}');

                // Share  
                await Share.shareXFiles(
                  [XFile(file.path)],
                );
              },

Share from assert/local

      onPressed: () async {
                final dir = await getTemporaryDirectory();
                final byte = (await rootBundle.load("assets/images/download.png")).buffer.asUint8List(); // convert in to Uint8List
                debugPrint('byte $byte');
                final file = File("${dir.path}/Image.png") ; // import 'dart:io'
                await file.writeAsBytes(byte);
                // Share
                await Share.shareXFiles(
                  [XFile(file.path)],
                );
              },

我通过将 share_plus 版本从 7.0.2 降级到 7.0.0 来解决了这个问题。

final directoryPath = (await getTemporaryDirectory()).path;
final imagePath = '$directoryPath/qrimg.png';
final imageFile = await File(imagePath).create(recursive: true);
imageFile.writeAsBytesSync(byteData.buffer.asUint8List());

final file = XFile(imagePath);
await Share.shareXFiles();

Flutter SDK - 3.7.11
Android 版本 12

I was able to resolve this issue by downgrading the share_plus version from 7.0.2 to 7.0.0.

  final directoryPath = (await getTemporaryDirectory()).path;
  final imagePath = '$directoryPath/qrimg.png';
  final imageFile = await File(imagePath).create(recursive: true);
  imageFile.writeAsBytesSync(byteData.buffer.asUint8List());

  final file = XFile(imagePath);
  await Share.shareXFiles();

The shareXFiles function似乎仅使用缓冲数据运行。通过使用rootBundle.load加载图像,在我的情况下可以解决该问题。

void share(BuildContext context) async {
    final box = context.findRenderObject() as RenderBox?;
    final data = await rootBundle.load('assets/images/example.jpg');
    final buffer = data.buffer;

    await Share.shareXFiles(
      [
        XFile.fromData(
          buffer.asUint8List(data.offsetInBytes, data.lengthInBytes),
          name: 'example.jpg',
          mimeType: 'image/jpeg',
        ),
      ],
      sharePositionOrigin: box!.localToGlobal(Offset.zero) & box.size,
    );
}
英文:

shareXFiles function seems to be working with buffer data only. Loading images via rootBundle.load fixes the problem in my case.

void share(BuildContext context) async {
    final box = context.findRenderObject() as RenderBox?;
    final data = await rootBundle.load('assets/images/example.jpg');
    final buffer = data.buffer;

    await Share.shareXFiles(
      [
        XFile.fromData(
          buffer.asUint8List(data.offsetInBytes, data.lengthInBytes),
          name: 'example.jpg',
          mimeType: 'image/jpeg',
        ),
      ],
      sharePositionOrigin: box!.localToGlobal(Offset.zero) & box.size,
    );
  }
