I am building a plugin and need to make use of images (like Image.asset or Image.file) and need to pass them to my native plugin. However, I could not find a decent way to pass these. Does anyone know how to achieve that and how these objects are used natively in general?

You can pass the asset path and read it via Flutter:

  1. Pass the asset path through MethodChannel
  2. Look for the asset using it's path:
AssetManager assetManager = registrar.context().getAssets();
String key = registrar.lookupKeyForAsset("icons/heart.png");
AssetFileDescriptor fd = assetManager.openFd(key);
