after research I've tried the following
updating the java version to 20.0.1
java version "20.0.1" 2023-04-18 Java(TM) SE Runtime Environment (build 20.0.1+9-29) Java HotSpot(TM) 64-Bit Server VM (build 20.0.1+9-29, mixed mode, sharing)
down-grade Gradle version in Android/build.gradle from 7.2.0 to 4.1.0
but it did not work for me.
i'm not sure what exactly causes the problem but i think that the java version flutter uses is 1.8 while i already installed version 20.0.1 but i can not get flutter to use this version. if this is the case how can i do that. if not what could be the case
