android - Flutter Android 日志过多且冗长

问题描述

当我在 Android 模拟器上运行应用程序时，或者在物理设备上运行应用程序时，日志是巨大的，而且常常是压倒性的……我想知道如何只获取相关的输出，而不是像这样的不必要的日志：

W/om.tejas.pethu( 7618): Accessing hidden method Ljava/security/spec/ECParameterSpec;->getCurveName()Ljava/lang/String; (greylist, reflection, allowed)
I/ProviderInstaller( 7618): Installed default security provider GmsCore_OpenSSL
W/om.tejas.pethu( 7618): Accessing hidden field Ljava/net/Socket;->impl:Ljava/net/SocketImpl; (greylist, reflection, allowed)
W/om.tejas.pethu( 7618): Accessing hidden method Ldalvik/system/CloseGuard;->get()Ldalvik/system/CloseGuard; (greylist,core-platform-api, linking, allowed)
W/om.tejas.pethu( 7618): Accessing hidden method Ldalvik/system/CloseGuard;->open(Ljava/lang/String;)V (greylist,core-platform-api, linking, allowed)
W/om.tejas.pethu( 7618): Accessing hidden field Ljava/io/FileDescriptor;->descriptor:I (greylist, JNI, allowed)
W/om.tejas.pethu( 7618): Accessing hidden method Ljava/security/spec/ECParameterSpec;->setCurveName(Ljava/lang/String;)V (greylist, reflection, allowed)
W/om.tejas.pethu( 7618): Accessing hidden method Ldalvik/system/BlockGuard;->getThreadPolicy()Ldalvik/system/BlockGuard$Policy; (greylist,core-platform-api, linking, allowed)
W/om.tejas.pethu( 7618): Accessing hidden method Ldalvik/system/BlockGuard$Policy;->onNetwork()V (greylist, linking, allowed)

请记住，在运行时会产生大量的详细日志......这使得很难找到哪些日志是冗长和不必要的，以及您希望看到的日志是什么样的print('Hello');。

请注意，在像上面这样的详细日志中查找这个Hello字符串至少可以说是具有挑战性的。

这与干净且不冗长的 iOS 日志相比：

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...
Xcode build done.                                           33.6s
Configuring the default Firebase app...
Configured the default Firebase app __FIRAPP_DEFAULT.
Connecting to VM Service at ws://127.0.0.1:54149/6CwtGLU6Ci0=/ws

值得注意的是，在运行时，只显示重要的日志/必要的日志，如 Dart 编译器错误和print语句。

我要问的是：

  1. 有没有办法过滤这些日志，以便我只得到 Dart/Flutter 编译器产生的打印语句和错误？

  2. 如果不可能，有没有办法以非黑客的方式停止这些日志？我不想进入任何在幕后为我们编写的复杂源代码......

flutter run -d <device-id>如果不超过上述值，则产生相同的多余日志：

感谢您为我提供的任何帮助，我很感激！
