Question

使用flutter build apk --release构建发行版APK时，出现以下构建错误，在调试模式下运行正常。

失败：生成失败，发生异常。

出了什么问题：
任务'：cloud_firestore：verifyReleaseResources'的执行失败。

java.util.concurrent.ExecutionException：com.android.builder.internal.aapt.v2.Aapt2Exception：Android资源链接失败 /home/seven/AndroidStudioProjects/appName/build/cloud_firestore/intermediates/res/merged/release/values/values.xml:276：错误：找不到资源android：attr / fontVariationSettings。 /home/seven/AndroidStudioProjects/appName/build/cloud_firestore/intermediates/res/merged/release/values/values.xml:277：错误：未找到资源android：attr / ttcIndex。错误：链接引用失败。
