flutter image map
flutter_image_map #
A simple but (hopefully) useful package that implements the HTML image map standard.
What is an Image Map? #
Originally introduced in HTML 3.2 as a replacement for server side imagemaps. Server side image maps were clunky requiring a round trip to the web server to determine where to go based on the coordinates clicked in the image. Thus client side image-maps were born!
An imagemap is a graphic image where a user can click on different parts of the image and be directed to different destinations. imagemaps are made by defining each of the hot areas in terms of their x and y coordinates (relative to the top left hand corner). With each set of coordinates, you specify a link that users will be directed to when they click within the area.
As an example, say you have a map of the World that you wish to act as an image map. Each country could have their hot areas defined on the map to take you to different pages.
Examples #
