使用 Flutter 共享插件共享文件时出现 PlatformException

如何解决使用 Flutter 共享插件共享文件时出现 PlatformException

我正在尝试从小部件创建图像并将其存储到文件中。然后允许用户共享图像。我们使用的是 Flutter 官方分享插件： https://pub.dev/packages/share

这是我的主要逻辑：

  void _convertReportToImageAndShare() async {
    final RenderRepaintBoundary renderRepaintBoundary =
        _containerKey.currentContext.findRenderObject();
    final image = await renderRepaintBoundary.toImage();
    final byteData = await image.toByteData(format: ImageByteFormat.png);
    final pngBytes = byteData.buffer.asUint8List();
    final tempDir = (await getTemporaryDirectory()).path;
    final filePath = '$tempDir/image.png';
    final file = await File(filePath).create();
    file.writeAsBytesSync(pngBytes);
    await Share.shareFiles([filePath]);
  }

该函数可以在iOS模拟器上成功运行。但是，在Android设备上运行时，会抛出PlatformException：

The following PlatformException was thrown:
PlatformException(error,Couldn't find Meta-data for provider with authority
{my application id}.Flutter.share_provider,null,java.lang.IllegalArgumentException:

 When the exception was thrown,this was the stack:

 <asynchronous suspension>

我检查了源代码，share_provider 定义在 https://github.com/flutter/plugins/blob/master/packages/share/android/src/main/AndroidManifest.xml

我该如何解决这个问题？我需要修改 AndroidManifest.xml 中的某些内容吗？谢谢！
