Sorry, I was in a hurry when asking the question as I had a class coming up. Let me restate the issue I encountered. When I use python3 blutter.py /home/von/桌面/lib/arm64-v8a output (the issue persists regardless of whether --rebuild is used), I encountered an undefined CSREG_DART_HEAP problem. I apologize that after looking at blutter/src/CodeAnalyzer_arm64.cpp, I couldn't understand what CSREG_DART_HEAP means, and therefore, I have no idea what it should be defined as. I apologize for my ignorance, and I would be extremely grateful if someone could help me solve this problem.

I couldn't understand what CSREG_DART_HEAP means

CSREG_DART_HEAP is Heap start Address where Darts Code Stack Registers gets loaded initially at runtime, Similarly there's Pool Heap offset for Dart's Object Pool and others.

Though your issue seems to be related to the library you're working on, can you share them if possible

@AbhiTheModder
Are you referring to the library file 'arm64-v8a' in the path /home/von/Desktop/lib/arm64-v8a in the command I'm supposed to execute? I can provide this library.Thank you very

Yes,

The file link you provided gives "not found" error.

I'm sorry, this is my first time using file upload. The zip file link I uploaded seems to show 'NOT FOUND' for some reason. Here is the link to my latest upload, could you please try to open it?

@Vonggg thanks worked now

[AbhiTheModder]

@Vonggg It is indeed an issue with the library you're working on.

The libflutter.so is 64-bit however libapp.so is of 32-bit and blutter doesn't support 32-bit.

Also if you want to know the solution to fix that CSREG_DART_HEAP error you can comment out it's defining condition in Disassembler_arm64.h but again due to libapp.so of being 32-bit you'll face below problem so it's better to fix your target binary

The is 64-bit however is of 32-bit and blutter doesn't support 32-bit.libflutter.so``libapp.so

Thank you very much for your help.

fixed in #103
