tomasbaran · 2020-07-30T13:47:22Z

@shily , this may be the same issue: #55952 which just got fixed in the latest master. Upgrade flutter to the latest master and check out whether #59855 got fixed too or not.

liushuai42 · 2020-08-27T09:17:11Z

flutter 1.20.2 still has this problem.

GaryQian · 2020-10-26T22:24:50Z

1.20.2 was not the master branch where it was reported fixed. Can you try it on master instead of stable?

Try flutter channel master and then flutter upgrade to change branches. Thanks!

liushuai42 · 2020-11-11T11:31:42Z

Master branch still has this problem.

iOS has a bad habit of keeping the old splash screen as a system cache. Simply uninstalling the app will not fix it. Either restart or clear your device cache

raymond-liao · 2023-03-09T12:06:50Z

I think it is the Flutter bug not iOS cache issue. I've tried the Native iOS project for localized Launch Screen, it works well. Here is the sample:

darshankawar · 2023-09-29T12:19:52Z

Verified this issue using latest stable version and running the repo provided in original description, I see that the behavior persists, as below:
