Unhandled Exception: MissingPluginException(No implementation found for method init on channel com.rebeloid.unity_mediation)

I am using a unity mediation for my app. I am trying to initialize it with this code

UnityMediation.initialize(
    gameId: GetPlatform.isAndroid ? '4865xxx' : '4865xxx',
    onComplete: () => print('Initialization Complete'),
    onFailed: (error, message) => print('Initialization Failed: $error $message'),
  );
  UnityMediation.loadRewardedAd(
    adUnitId: GetPlatform.isAndroid ? 'Rewarded_Android' : 'Rewarded_iOS',
    onComplete: (adUnitId) => print('Rewarded Ad Load Complete $adUnitId'),
    onFailed: (adUnitId, error, message) => print('Rewarded Ad Load Failed $adUnitId: $error $message'),
  );

Following all the documentation provided but get an error like this one

What is the cause of this problem? I have trying to search but nothing found about this one. Thank you.

>Solution :

Quit the app and run it again. The native code from the package isn’t on the device until do a full start. Hot reload and hot restart won’t work after using a newly installed package.
