Image Keyboard for other platforms

[Shawn-sudo]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Use case

#20796 has been marked as fixed by #110052 and is closed & locked now, but #110052 implemented it only for Android; on iOS, Web, and other platforms, contentInsertionConfiguration hasn't been implemented, and I think this should be tracked somewhere.

• Web: The demo on the api reference page doesn't work, and the page doesn't mention the fact that it's implemented only for Android yet

• iOS: I tried copy&pasting an image into a textfield with contentInsertionConfiguration configured, but it just shows the raw data without invoking onContentInserted

Proposal

• Update the api reference page to indicate that contentInsertionConfiguration is only implemented for Android yet
• Track the implementation of image keyboard feature for iOS and other platforms
  • Related: https://stackoverflow.com/questions/56615542/how-to-allow-and-get-memoji-stickers-in-a-text-field
    • It talks about handling Memoji sticker (= png image) input on iOS

@Shawn-sudo

Per ContentInsertionConfiguration class documentation, it does mention that following properties are used for Android only:

onContentInserted : https://api.flutter.dev/flutter/widgets/ContentInsertionConfiguration/onContentInserted.html
allowedMimeTypes: https://api.flutter.dev/flutter/widgets/ContentInsertionConfiguration/allowedMimeTypes.html

As for support for other platforms (web, ios), treating this as a proposal as applicable.

Thanks for opening this! You're right that we don't seem to have anywhere that we were tracking image keyboard support for other platforms, good catch. It is something we want to support.
