Issues Compiling my app after Stripe Implementation

[max-anders]

Hello, I am facing build errors after trying to implement Stripe into my Flutter project. The update steps seems to have caused multilpe conflicts, possibly with other packages. encountered various errors related to Kotlin, Java, Gradle, and other dependencies.

I followed each step mentionned in the guide and copied some of the values provided on the example github repo.

• I got an error that required my to update to build.grade 8.4,

tried to update build gradle manually but had some errors then I tried to update it using upgrade assistant from android studio (initially it didn't show up)

I tried those commands in android studio (opening both android as a project and the project itself)

(flutter clean, flutter pub cache repair, flutter pub outdated ) and using invalidate cache option in android

I tried various version of kotlin (initially had 1.7.10, tried every version from there) some times it says that it can't find the kotlin version (1.8.10) but it seems change the gradle version has an effect on this

• I tried flutter upgrade and so I tried flutter downgrade and it doesnt change anything (downgraded from flutter 3.22.. to 3.19.2 if I recall corectly)

• I tried using multiple versions of the stripe package, curently on 10.0.0

One long error looked something like this

java.lang.Exception
	at org.jetbrains.kotlin.daemon.common.CompileService$CallResult$Error.get(CompileService.kt:69)
	at org.jetbrains.kotlin.daemon.common.CompileService$CallResult$Error.get(CompileService.kt:65)
	at org.jetbrains.kotlin.compilerRunner.GradleKotlinCompilerWork.compileWithDaemon(GradleKotlinCompilerWork.kt:244)
	at 

current error :

`* What went wrong:
Execution failed for task ':on_audio_query_android:compileDebugKotlin'.

Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'compileDebugKotlin' (17).`

• I changed java in build gradle to version 17 already but this still show up

my build.gradle.

 `buildscript {
    ext.kotlin_version = '1.9.20'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:8.1.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    afterEvaluate { project ->
        if (project.hasProperty('android')) {
            project.android {
                if (namespace == null) {
                    namespace project.group
                }
            }
        }
    }
}
subprojects {
    project.evaluationDependsOn(':app')


}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

By the way, I got a missing namespace error (even though I have one) that I managed to fix by adding this to the build gradle

´´´
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
afterEvaluate { project ->
if (project.hasProperty('android')) {
project.android {
if (namespace == null) {
namespace project.group
}
}
}
}
}
´´´

Can anyone help me debug or provide a way to get my project to compile again?
Thank you for your help.
