my_data_state 0.0.1

A simple package to encapsulate the state of data (loading, loaded, exists, not exists)

DataState is a micro library to represent the state of data.

It contains the following classes:

• DataState (abstract)
  • DataStateLoading
  • DataStateLoaded
    • DateStateExists
    • DateStateNotExist

Usage:

void main() {
  const loading = DataStateLoading();
  print(loading);
  final loaded = DataState.loaded(3);
  print(loaded is DataStateExists);
  print(loaded.data); // 3
  final notExist = DataState.loaded(null);
  final notExistList = DataState.loaded([]);
  print(notExist is DataStateNotExists);
  print(notExistList is DataStateNotExists);
}
