It means you have "some" error within your

android { ... }

closure. Unfortunately the Groovy DSL does not show a better error message. That's one of the reasons I greatly prefer the Kotlin DSL. There you have amazing IDE support and type-safe build scripts with proper error messages. In Groovy DSL the best I know to investigate in your case is either to see the error or to comment out everything and comment in line by line or block by block to find the culprit.

it says on line 28 so could the culprit be after or just anywhere?

Line 28 is where your

android { ... }

closure starts. The problem is within that closure

FYI we found a bug on the Gradle side that did not help the reporting, it will be fixed in Gradle 7.5

Hey! Just wanted to make sure you are aware of a #C03EM93810S specific channel. It is new but this way we can focus flutter issues.
