I am trying solution mentioned in https://github.com/shounakmulay/Telephony/issues/165

telephony:
  git:
    url: https://github.com/definev/Telephony.git
    ref: develop

change is adding @pragma('vm:entry-point') to telephony.dart method

Not sure if and when it will merged to original package.
