How can it be achieved? The animation plugins in flutter that i have researched so far does not provide this functionality.

Solution

  • Since this is only about windows platform, I found a WIN32 API that may meet your needs.

    Follow this link: https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-animatewindow

    Here is a YouTube video on it: https://www.youtube.com/watch?v=meIci7gOTLk

    You can call the api using win32 package in your flutter application. Here is the link: https://pub.dev/documentation/win32/latest/winrt/AnimateWindow.html

    As per its documentation, the API enables you to produce special effects when showing or hiding windows. There are four types of animation: roll, slide, collapse or expand, and alpha-blended fade.
