Fresh Project Using Insecure APIs (_sscanf, _strlen, _fopen, malloc) in Binary

Hello Apple Developer Community,

I recently created a fresh project with:

No dependencies

No additional written code

After generating the iOS build, I navigated to the build folder:

cd build/ios/iphoneos/Runner.app

Then, I ran the following commands to inspect the binary:

otool -Iv Runner | grep -w _strlen

otool -Iv Runner | grep -w _malloc

Surprisingly, I received positive results, meaning these functions are present in the binary.

My Questions:

Why is a fresh Flutter project (with no extra dependencies) including these APIs in the binary?
