How can resolve this issue?

Answer 1

Even if my answer is late, I had the same problem and finally found the answer. On Dart pub the plugin is tagged as compatible with iOS. However, on the project description it states:

Notes
iOS not supported currently - I do not own a Mac, so deploying for iOS will be a little slow.

So I guess you will have to implement it yourself.
