I recently changed the color palette for my flutter app. However, when I run it I initially see the old color palette.

The only way to see the new changes is to tap restart even when it is a fresh instance.
This is iOS. I’ve have tried Erase All Content and Settings (which ought not be necessary) but to no avail.

flutter doctor is clean – no issues.

No errors shown in the console.

Any guidance would be appreciated.
