我已经创建了这个功能，在许多应用程序上很好地共享图像，但当涉及到WhatsApp或Instagram时，它不会共享图像。

我正在使用Ionic v5和电容器v3

async shareImage() {
    let receiptName = 'Receipt N:123.png';
    const div = this.screenshotElement.nativeElement;
    const divHeight = div.clientHeight;
    const divWidth = div.clientWidth;
    const options = { background: '#ffffff', width: divWidth, height: divHeight };

    await Filesystem.requestPermissions();

    let base64Data = await domtoimage.toPng(div, options);

    // device shareing
    await Filesystem.writeFile({
      path: receiptName,
      data: base64Data,
      directory: Directory.Cache
    });

    let fileResult = await Filesystem.getUri({
      directory: Directory.Cache,
      path: receiptName
    });

    let imageLink = Capacitor.convertFileSrc(fileResult.uri);

    Share.share({
      title: receiptName,
      text: receiptName,
      url: fileResult.uri,
    })
      .then(() => console.log('Successful share'))
      .catch((error) => console.log('Error sharing ::: ', error));

  }
