Describe the problem

Complete details logs :

Note : I have also applied flutter clean then flutter pub get and invalidated caches IDE and removed caches gradle as well.
Note 2 : Tried both gradle 7.6.1 and 7.6.4 and downgrading JDK to 17 or 19 is not a solution either

@parlough, this was an issue in Flutter 3.10, a long time ago. Do you have any idea if this is still relevant?
