Share image

[millordd]

I'm using Capacitor 6.0.3 with @capacitor/share.

According to the docs, ShareOptions supports:

• title
• text
• url (http, https, file://)
• files (array of file:// URLs)

My problem:
I have an image generated in WebView (screenshot) as a data URL / Blob / base64 string.
I want to share this image using Share plugin without manually creating a file URI.

What I tried:

• Passing data:image/png;base64,... to url → not supported
• Passing blob: URL → not supported
• Creating File object in JS → native layer can't access it
• navigator.share → unreliable in Android WebView

Current working solution:
Save base64 to Filesystem (Cache) → getUri → Share.share({ files: [uri] })

Question:
Is there any supported or recommended way in Capacitor 6 to share an image
directly from memory (base64/blob) without writing it to the filesystem,
or is writing a temporary file the only correct approach?

Environment:

• Capacitor 6.0.3
• @capacitor/share 6.0.3
• Android WebView (Ionic/Capacitor app)
