我读过@mraleph的文章，但仍然无法理解其中的内容 .so 由FlatterAndroid生成的文件。
我做了一个实验：对于我自己的应用程序，我从apk文件中提取.so( mkdir -p 07260818_apk_unzip && unzip 07260818.apk -d 07260818_apk_unzip )，并将说明转储( objdump -d ./07260818_apk_unzip/lib/armeabi-v7a/libapp.so > objdump.txt ). 我还分割调试信息并进行模糊处理，所以我还转储了矮人信息( drawfdump ).
我手动抛出一个异常，如

// debug_page.dart
              OutlinedButton(
                onPressed: () => throw Exception('hello exception (from simply onPressed) ${DateTime.now()}'),
                child: Text('normal'),
              ),

然而，这很奇怪。0x5dfbdb上根本没有指令(这就像是在指令的中间。另外，dart编译器生成的.so文件只不过是机器指令吗？我在.so文件中没有看到dart vm。
谢谢你的建议！
