@ionic-native/call-number not working

Ionic Native
1

Getting error while running ionic app.

ERROR in @ionic-native\call-number\index.ts(25,2): Error during template compile of ‘CallNumber’
Only initialized variables and constants can be referenced in decorators because the value of this variable is needed by the template compiler in ‘Plugin’
‘Plugin’ references ‘Plugin’
‘Plugin’ is not initialized at @ionic-native\core\decorators\interfaces.ts(100,22).

Is there anyone to give or suggest answer for this question.
Please help me with that.

I used Ionic 4 here.
