There are many flutter packages that use dynamic libraries and ffi dart, many of the creators of those packages forget to implement this (big mistake): https://github.com/simolus3/drift/issues/895 and https://stackoverflow.com/questions/65551415/failed-to-load-dynamic-library-in-flutter-app Where it is specified that the dynamic library should be opened from java (on Android) with: System.loadLibrary(), since with DynamicLibrary.open() you get "library not found" on older devices (SDK<=23). It took me a week to go through this package and get it working as I know very little about native code, here is the fork if it helps: https://github.com/jpolstre/flutter_js

The error may be due to the quickjs library not being imported correctly in the flutter_js plugin, you can try adding the dependency to your project in android/app/build.gradle:

  dependencies{
  ....
  //add this
  implementation "com.github.fast-development.android-js-runtimes:fastdev-jsruntimes-quickjs:0.3.5"
}

And also in android/build.gradle:

allprojects {
  repositories {
  google()
  mavenCentral()

  //add this
  maven { url 'https://jitpack.io' }
}
