checkServiceStatus method

@override Future<ServiceStatus> checkServiceStatus(Permission permission)

Checks the current status of the service associated with the given Permission.

Notes about specific permissions:

• Permission.phone
  • Android:
    • The method will return ServiceStatus.notApplicable when:
      • the device lacks the TELEPHONY feature
      • TelephonyManager.getPhoneType() returns PHONE_TYPE_NONE
      • when no Intents can be resolved to handle the tel: scheme
    • The method will return ServiceStatus.disabled when:
      • the SIM card is missing
  • iOS:
    • The method will return ServiceStatus.notApplicable when:
      • the native code can not find a handler for the tel: scheme
    • The method will return ServiceStatus.disabled when:
      • the mobile network code (MNC) is either 0 or 65535. See https://stackoverflow.com/a/11595365 for details
  • PLEASE NOTE that this is still not a perfect indication of the device's capability to place & connect phone calls as it also depends on the network condition.
