Invalid argument(s): Failed to load dynamic library 'libopencv_dart.so'

[cuishijie1991]

Hello
I am developing an app using the opencv_dart plugin. With it, I can easily implement image operations such as grayscale conversion and pencil drawing conversion. It is really great!
When I run it on an old tablet, I encounter an error loading lib. If possible, please help me analyze the reason.Thank you very much!

E/flutter ( 5108): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Invalid argument(s): Failed to load dynamic library 'libopencv_dart.so': dlopen failed: empty/missing DT_HASH in "libopencv_dart.so" (built with --hash-style=gnu?)

To Reproduce
just call
var kernel = cv.getStructuringElement(cv.MORPH_RECT, (kernelSize, kernelSize));
In fact, opencv cannot be initialized, and calling any API will result in an error

Smartphone (please complete the following information):

• ABI Version [android-x64]

opencv_dart: 1.2.5

@cuishijie1991 API level 22 is not supported, the minimum supported API is 24.

It's because some videoio API only available since 24, you can compile opencv and dartcv from source to make it work on API 22.

Thank you for your replay, I will try!
