flutter 升级后报一大堆错误 主要是在打包Android的时候会报错，iOS比较熟，问题都能解决，执行flutter build apk Android的报错如下

* What went wrong:                                              
Running Gradle task 'assembleRelease'...                                                         Execution failed for task ':app:lintVitalRelease'.              
Running Gradle task 'assembleRelease'...                                                         > Could not resolve all artifacts for configuration ':app:debugRuntimeClasspath'.
Running Gradle task 'assembleRelease'...                                                            > Could not resolve io.flutter:arm64_v8a_debug:1.0.0-a67792536ca236a971d0efbcfd7af4efb8f6c119.
Running Gradle task 'assembleRelease'...                                                         

从报错信息可以看出 错误地方在于Execution failed for task ‘:app:lintVitalRelease‘

解决方法：
在android->app->build.gradle中android路径下添加如下代码

    lintOptions {
        disable 'InvalidPackage'
        checkReleaseBuilds false
        abortOnError false
    }

重新执行 flutter build apk即可正常打包

flutter Execution failed for task ':app:lintVitalRelease'.
