Flutter构建Proguard配置规则与任何内容都不匹配

Question

我正在运行 Flutter 发布版本并收到警告Proguard configuration rule does not match anything。完整列表见下文。

这应该提交给 Flutter GitHub 问题还是我做错了什么？

我的构建命令是：（ flutter build appbundle --release --obfuscate --split-debug-info=./build/symbols 如果我删除--obfuscate标志也会发生同样的情况）

我的项目不包含任何proguard-rules.pro文件。

我的app/build.gradle配置是：

buildTypes {
        release {
            signingConfig signingConfigs.release

            ndk {
                abiFilters 'arm64-v8a', 'armeabi-v7a', 'x86_64'  //, 'x86'
            }

            minifyEnabled true
            shrinkResources true
           
        }
    }
}

我正在使用以下构建工具和设置：

• 摇篮8.4
• Gradle 插件 8.1.2
• 科特林 1.9.10
• 爪哇17
• ndk 版本 26.0.1909125
• 编译SdkVersion 34
• minSdkVersion 28
• 目标SDK版本34
