This is part of the log I got:

**`FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ‘:app:dexBuilderDebug’.

There was a failure while executing work items

This is my project’s android/build.gradle file:

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

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

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

This is my project’s android/app/build.gradle file:

plugins {
    id "com.android.application"
    id "kotlin-android"

if (flutterVersionCode == null) {
    flutterVersionCode = '1'

            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'

I tried to make some modifications on android/app/build.gradle, cleaning flutter cache, and rebuilding the project but I got another error.
