my_data_state 0.1.0

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)
  • DataLoading
  • DataLoaded (abstract)
    • DateExists
    • DateNotExist

Usage:

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