AsyncState<T> class sealed

Represents the state of an asynchronous operation.

AsyncState is a sealed class that represents different states of async operations:

Example:

AsyncState<String> state = AsyncLoading<String>();

if (state.isLoading) {
  print('Loading...');
} else if (state.isSuccess) {
  print('Data: ${state.data}');
} else if (state.isError) {
  print('Error: ${state.error}');
}
