Hi @g123k ,
I suggest using this approach to solve the issue. Please let me know whether I should proceed with it or for any better approach.

What if we just disable the button after the first click? The screen shouldn't be reachable anymore after it.

Frankly do we need to block the user to wait for the download ? We do have a local copy of the product in English as a failsafe

From the point of view of UX, a little Load time is acceptable, but spamming a button feels just like a bug

Whether you can dismiss this route by tapping the modal barrier.

showDialog(
  barrierDismissible: false,
  builder: ...
)

showDialog(
  barrierDismissible: false,

that would block the user from interacting with the screen, seems like a good idea
