In Notifier, should any late initialized properties be initialized in built()

[hamishjohnson]

I have a Notifier provider like so

class SharedPrefsNotifier<T> extends Notifier<T> {
  final String key;
  final T defaultValue;
  late SharedPref<T> sharedPref;

  SharedPrefsNotifier(this.key, this.defaultValue);

  @override
  T build() {
    sharedPref =
        SharedPref<T>(ref.read(sharedPreferencesProvider), key, defaultValue);

    return sharedPref.get();
  }

  T set(T value) {
    sharedPref.set(value);
    state = value;
    return value;
  }
}

This works well, except when I move the sharedPref = Share... code into the constructor. For some reason, it seems build is called before the constructor, and so any late properties accessed in build will error if you initialize it in the constructor.

Yes, so that in build.

Notifier shouldn't have constructors.
