is it possible to a take screenshot of the app screen and share it on social media (whatsapp, telegram, etc) as jpeg/png file without the use of extensions?
i am using an IOS device which does not support extensions hence unable to use existing screenshot extensions
I believe all you can do is use the device's method for screenshotting, and then recover the image from the directory where screenshots are saved.
An alternative may be to run all your apps activities, or at least the ones you want to screenshot, inside a canvas, then you can save the canvas as an image. This could work well with some lateral thinking...
