Hi @thangldvn. Thanks for filing this issue. I am unable to reproduce this on both Android and iOS with the latest stable version. Kindly confirm this issue on the latest version and also confirm you added the const keyword when trying to get environment variables using String.fromEnvironment().

Thanks for your reply @dam-ease . I have found the issue; that is my project has been removed 2 files: Debug.xcconfig and Release.xcconfig, after i create new files, it was placed in wrong folder (not in ios/Flutter/ Folder). Then i move 2 files in to ios/Flutter/ and now it works fine
