我使用flutter_tflite: ^1.0.1开发实时目标检测应用，模拟器测试一切正常，但构建APK和App Bundle时出现以下错误：

Execution failed for task ':flutter_tflite:verifyReleaseResources'.

A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action

flutter doctor结果 #

这个错误是因为flutter_tflite: ^1.0.1依赖的AndroidX库版本与项目compileSdk不匹配，android:attr/lStar是Android 12L（API 32）及以上才新增的属性，老旧版本的flutter_tflite未适配高版本compileSdk。可按以下方案解决：

方案1：强制统一AndroidX库版本 #

修改android/build.gradle中的subprojects块，强制所有子模块使用适配高compileSdk的AndroidX库版本：

subprojects {
    project.evaluationDependsOn(":app")
    project.android {
        if (project.hasProperty('android')) {
            compileSdkVersion 35
            defaultConfig {
                minSdkVersion 23
            }
            configurations.all {
                resolutionStrategy {
                    force 'androidx.appcompat:appcompat:1.6.1'
                    force 'androidx.core:core-ktx:1.12.0'
                }
            }
        }
    }
}

方案2：迁移到官方维护的TFLite插件 #

flutter_tflite已停止维护，建议替换为TensorFlow官方提供的tflite_flutter插件，兼容性和稳定性更好：

1. 修改pubspec.yaml中的依赖：

   dependencies:
     # flutter_tflite: ^1.0.1
     tflite_flutter: ^0.10.1
     tflite_flutter_helper: ^0.4.0 # 可选，提供模型推理辅助工具
   

2. 替换原有flutter_tflite的调用代码为tflite_flutter的API，官方文档有完整迁移指引。

方案3：降低compileSdk版本 #

如果暂时不想调整依赖，可将app/build.gradle中的compileSdk = 35改为compileSdk = 31，避开lStar属性的版本要求，但可能影响其他新API的使用。
