Flutter集成Zoom Video SDK时Release构建遇Kotlin版本不兼容问题

问题概述 #

使用Flutter 3.7.7开发应用，集成Zoom Video SDK后，USB调试运行正常，但执行flutter build apk --release构建Release版本时，出现Kotlin版本不兼容错误（依赖模块编译用Kotlin 1.8.0，项目期望1.6.0），同时伴随API废弃、不安全操作提示。已尝试./gradlew clean和../gradlew assembleRelease，问题未解决。

gradle配置（android/app/build.gradle） #

defaultConfig {
    minSdkVersion 24
    targetSdkVersion 33
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    
}

buildTypes {
    release {
        // 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
         ext.kotlin_version = '1.4.32'
    }
}

flutter {
source '../..'
}

dependencies {
    implementation "us.zoom.videosdk:ZoomVideoSDK:0.0.1-beta"
    implementation "org.jetbrains.kotlin:kotlin-stdlib:1.8.21"
}

解决步骤 #

1. 修正Kotlin版本配置位置
   打开项目根目录的android/build.gradle文件，将Kotlin版本配置移至buildscript块中，设置为与依赖匹配的1.8.21，示例：

   buildscript {
       ext.kotlin_version = '1.8.21'
       repositories {
           google()
           mavenCentral()
       }
       dependencies {
           classpath "com.android.tools.build:gradle:7.4.2"
           classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
       }
   }
   

   同时删除android/app/build.gradle中buildTypes > release块内的ext.kotlin_version = '1.4.32'配置。

2. 清理缓存并重新构建
   依次执行以下命令：

   flutter clean
   rm -rf android/.gradle
   flutter build apk --release
   

3. 处理API废弃提示（可选）
   报错中的API废弃、不安全操作提示来自第三方依赖库，不影响构建成功。若要消除这些提示，可尝试将对应依赖包升级到最新兼容版本（如cloud_firestore、flutter_zoom_videosdk）。
