when i look source code of getPictures() , the implementation is not done yet
how does it work? below is the source code
any hint will be more than welcome!
what i need to do is put checkmark for selected image by image picker
You are looking at the wrong place. The ionic native wrappers are just that - typescript wrappers around cordova plugins. You need to modify the cordova plugin method it wraps around. Read the ionic native developer guide for how it works - the functions you are pointing to are just stubs.
I’d recommend you fork the cordova-plugin though and use that instead of modifying the core cordova plugin - that way if you ever remove/re-add, your changes will be maintained.
