Undo Button Routes the screen to the initial state

[infiniteoverflow]

This could be considered as an enhancement to the existing code.

How to reproduce :

• In the HomePage , choose either of the FAB button (Take an image / Open gallery).
• Once an image is selected , it will be redirected to the Imageview class.
• At the bottom we have an Undo button which routes to the same class to undo the changes that was brought to the image.

Solution :

• We can have a dynamic list where we can keep on appending the changed image files.
• On pressing undo , we can just setState the file attribute with the list.length - 1 index file image , which can revert back to the previous file image state.
