It is possible to implement Commit Content API using Flutter's TextField or TextFormField or any widget?

https://developer.android.com/guide/topics/text/image-keyboard

I am not sure convert this line

layout.addView(createEditTextWithContentMimeTypes(new String[]{"image/gif"}));

from this code example
