解决方案 #

步骤1：统一Kotlin与Gradle插件版本兼容性 #

当前使用的Gradle插件版本是7.3.1，该版本适配Kotlin 1.8.x系列，过高的Kotlin版本会触发不兼容问题。修改项目根目录的build.gradle文件：

buildscript {
    // 修改为适配Gradle 7.3.1的Kotlin版本
    ext.kotlin_version = '1.8.20'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

步骤2：清理缓存 #

错误来自Gradle缓存的旧版本文件，需要彻底清理：

• 执行命令：flutter clean
• 可选：手动删除本地Gradle缓存目录C:/Users/azimz/.gradle/caches

步骤3：重新构建 #

运行flutter build apk重新构建APK，验证错误是否解决。

额外说明 #

Gradle插件与Kotlin版本存在对应关系，后续升级时需注意匹配：

• Gradle插件7.3.x → Kotlin 1.8.x
• Gradle插件7.4.x → Kotlin 1.8.x/1.9.x
