error: The getter 'root' isn't defined for the type 'Logger'

[s-mehrabi-amp]

After adding the dependency and importing the library, I get
error: The getter 'root' isn't defined for the type 'Logger'. (undefined_getter at [******] lib\main.dart:17)
and
error: There's no constant named 'ALL' in 'Level'. (undefined_enum_constant at [******] lib\main.dart:18)
when I try to call activateLogcat()

Future initLogging() async {
  Logger.root.activateLogcat();
  Logger.root.level = Level.ALL;
}

This sounds like you haven't important the Logger library. My library is just an extension of the general Logger library. Without it, it won't work.
