集成OpenCV后Flutter构建Prod环境APK失败问题求助

我在Flutter项目中集成了Android版OpenCV SDK，调试模式下运行完全正常，但执行flutter build apk --flavor prod构建正式环境APK时，触发了R8编译错误，提示org.opencv.BuildConfig被多次定义，错误日志如下：

ERROR:C:\Users\Wesley\.gradle\caches\transforms-3\a70cc01f707cb65bbfec9756913c8264\transformed\jetified-opencv_android_module-3.1.0-fix3-runtime.jar:

已尝试的解决方案 #

• 执行Android Studio的Invalidate Caches/Restart操作
• 删除项目根目录及用户目录下的.gradle缓存文件夹
• 删除项目的build文件夹
• 组合上述操作后重新同步Gradle、清理项目并重新构建
• 将主项目的flavor配置复制到OpenCV模块的build.gradle文件中

以上操作均未解决问题，调试模式下OpenCV的使用完全正常，仅构建prod flavor的release包时会触发错误。

相关配置代码 #

app/build.gradle 依赖配置 #

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    implementation platform('com.google.firebase:firebase-bom:29.0.4')
    implementation 'com.google.firebase:firebase-analytics-ktx'
    implementation 'com.google.firebase:firebase-crashlytics-ktx'
    implementation project(path: ':openCV:sdk')
}

app/build.gradle BuildTypes与Flavors配置 #

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            debuggable false

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
        debug {
            shrinkResources false

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

flavorDimensions "appMode"
    productFlavors {
        qa {
            dimension "appMode"
            //applicationIdSuffix ".debug"
            manifestPlaceholders = [appName: "@string/app_name_qa"]
        }
        prod {
            dimension "appMode"
            manifestPlaceholders = [appName: "@string/app_name"]
        }
    }

我尝试了所有能想到的常规解决方案都无效，希望能得到针对性的解决建议。
