从log上开是由于couldn’t find "libflutter.so导致的，在build.gradle中对so架构过滤下，以及添加下packagingOptions：

defaultConfig {
        applicationId "org.devio.fluttertrip"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        ndk {
            abiFilters "armeabi-v7a","arm64-v8a","x86_64","x86" //只打包flutter所支持的架构，flutter没有armeabi架构的so，加x86的原因是为了能够兼容模拟器
        }
    }
...
packagingOptions {
    // 确保app与asr_plugin都依赖的libflutter.so merge时不冲突@https://github.com/card-io/card.io-Android-SDK/issues/186#issuecomment-427552552
    pickFirst 'lib/x86_64/libflutter.so'
    pickFirst 'lib/x86/libflutter.so'
    pickFirst 'lib/arm64-v8a/libflutter.so'
}

这个在课程中有讲哦，可参考下：https://git.imooc.com/coding-321/flutter_trip/src/master/android/app/build.gradle#L47

另外，上述配置完成之后建议删除所有build然后重新打开并运行项目试下。
