Using imencode and Mat.fromList throws error #111

Question

When trying to use imencode function I keep getting error:

Usage: imageData is Uint8List representing jpeg image. final mat = imdecode(imageData, IMREAD_UNCHANGED);

Error: [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Invalid argument(s): Failed to lookup symbol 'VecUChar_NewFromPointer': dlsym(RTLD_DEFAULT, VecUChar_NewFromPointer): symbol not found

Also I've tried to convert Uint8List to Mat using Mat.fromList constructor, but it throws an error as well.

Usage: final mat = Mat.fromList(height, width, MatType.CV_8UC1, imageData.toList());

Error: [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Invalid argument(s): Failed to lookup symbol 'Mat_NewFromBytes': dlsym(RTLD_DEFAULT, Mat_NewFromBytes): symbol not found

I'm not getting it. Is something wrong with my bytelist or it its something with implementation of those methods?

Looks like your dynamic library is broken, please update to the newest version or run setup manually with -f flag to overwrite the existed library and try again.
