Frequent flashes on Flutter
Rapidly flashing images or views (more than three flashes per second) can cause seizures for some users. You need to make sure this is not the case when designing and developing an app.
In Flutter, flashing content often uses widgets that change on changes from a Stream. For example, this could happen by using a StreamBuilder, and thus requesting a re-draw of certain parts of the screen. Check if these objects are used to show more than three flashes per second.
If your app contains any videos, also check if these contain more than three flashes per second.
