配置完成之后在模拟器上能正常运行，但是在真机上运行闪退，我的手机是小米6，不知道怎么回事，以下是错误信息

出错的原因在于flutter的架构"libflutter.so"没有打包进去导致的，需要配置下你的build.gradle，这个在课程中有讲到哦：
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 // abiFilters "armeabi-v7a" //release 时只打"armeabi-v7包 } } ... 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' }请参考：https://git.imooc.com/coding-321/flutter_trip/src/master/android/app/build.gradle#L47
