This is another battle entirely, the main reason for this is that Google can’t crawl or understand flash content effectively. They do have the ability to index text in flash files but that’s about as advanced as their crawlers are at the moment.
It is widely accepted that sites should do their best to remove any flash content as it’s not visible on mobile devices and can lead to your site being penalised as it will as not be classified as being mobile friendly(2).
If the flash content is mandatory for your site then we recommend replacing it with something else if a user is viewing your site on a mobile or tablet.
With that in mind we must also consider the value that the web widget provides to the user because at the end of the day Google would rather you optimise your website for the user opposed to search engine crawlbots and therein lies the balance between user and Googlebots that you have to achieve.
