build method

@override PagingState<PageKeyType, T> build(PageKeyType arg)

Initialize an AsyncNotifier.

It is safe to use Ref.watch or Ref.listen inside this method.

If a dependency of this AsyncNotifier (when using Ref.watch) changes, then build will be re-executed. On the other hand, the AsyncNotifier will not be recreated. Its instance will be preserved between executions of build.

If this method throws or returns a future that fails, the error will be caught and an AsyncError will be emitted.

Implementation

@override
PagingState<PageKeyType, T> build(PageKeyType arg) {
  // Initialize the state when the PagingController is built
  return PagingState<PageKeyType, T>(
    nextPageKey: arg,
    itemList: null,
    error: null,
  );
}
