Adobe Flash has not been very active for some time. Flash was in a state of disarray with the advent of HTML 5. By the end of this December 2020, the last nail in the coffin of the flash will be nailed.
Flash became increasingly popular in computers in the early 2000s. Initially it was used for small animation but later it was also used for full-fledged website construction. The action script made the flash even more powerful.
Flash was first introduced in 1993 by Future Wave. It was later acquired by Adobe in 2005.
Flash is a vector based application. Therefore the graphics in the Flash application are pretty smooth. I think the Flash app is the most used to show video and build games.
Most UI developers have found time to learn to be fascinated by Flash. It is believed that developers who used to work on Flash have already switched to other platforms. What made flash even more appealing was the fact that 2D animations can be made very well in a very short time and can be learned quickly.
Thus ends an application that has stood for nearly a quarter of a century. I think the gap of the flash can be covered with HTML5. Changes are inevitable.
