1、 打正式包 运行报错 No pending exception expected: java.lang.ClassNotFoundException: Didn’t find class “

1、可能需要配置相关SDK 混淆规则，曾遇到没有配置百度SDK混淆规则导致报错

百度SDK混淆正确配置

-keep class com.baidu.** {*;}  ///保持com.baidu.**这个包里面的所有类和所有方法不被混淆。
-keep class mapsdkvi.com.** {*;}
-dontwarn com.baidu.** #忽略警告

导致错误的配置

-keep class com.baidu.** {*;}
-keep class vi.com.** {*;}  ///配置错误行
-dontwarn com.baidu.**

2、或者把混淆关了（最好不要这样做）

release {
    minifyEnabled false
}

/

2、Gradle task assembleRelease failed with exit code - Removing unused resources requires unused code shrinking to be turned on

详细错误

You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the
APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64,android-x64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

buildTypes - release， 添加 shrinkResources true

    buildTypes {

            signingConfig signingConfigs.release
            //移除无用的resource文件
            shrinkResources true
