title: How to prevent my JNI folder from rebuilding?
body: <p>Anytime I clear build folder in flutter (either with <code>flutter clean</code> or manually), my jni folder rebuilds (~40 mins). Is that possible to compile library to some binary, and use it from android without breaking any interfaces and functionality?</p>
  <p>P.S. My library consists of many folders and contains .mk, .c, .cpp, .h files.</p>
