ssl_verify_peer_cert not found

For context - I'm using an x86_64 Genymotion emulator.

While it finds one of the offsets, it's not the right offset for the SSL pinning so all the calls are still tunneled. The test apk in this repo works as normal.

Which version of android are you using

I've tested on this app and I can intercept the calls to pepsico.com. Please reopen and give more info in case it still won't work. Note that Flutter apps don't use the system's proxy settings, so you need to have a correct setup for non-proxy-aware apps. I don't have experience with Genymotion in this regard, but typical solutions are VPN / WIFI / ProxyDroid / iptables.

I have tested on an app built on native flutter and what I did is patched the app using objection and used the frida interception scripts from httptoolkit and instead of loading their interception scripts I used NVISO's
