网络问题吧

我今天打包也遇到了这个问题我是这么解决的:

打开 External Libraries-->Flutter Plugins-->dim-0.2.8-->android-->gradle.wrapper-->打开 gradle-wrapper.properties文件,将 distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip修改为 distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip
然后在打开 ..-->android-->build.gradle文件将

compileSdkVersion 27
    defaultConfig {
        minSdkVersion 16
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

修改为

compileSdkVersion 30
 defaultConfig {
        minSdkVersion 19
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

我通过这个方式修改源文件就可以编译正常,如果你还在用,希望可以帮到你
