AsyncNotifierProviderのrefresh時にloading状態にする

0
Last updated at Posted at 2023-11-28

ref.refreshを使う場合に、画面が瞬間的に切り替わってLoading状態になりませんでしたが、
こちらに書いてありましたのでメモ。

以下のコードのどちらかを書けばOK.

List.dart
return somethingList.when(
      loading: () => const LoadingIndicator(),
      error: (err, stack) => Text('エラー'),
      skipLoadingOnRefresh: false, // ← 選択肢①
      data: (somethingList) {
        if (somethingList.isRefreshing) { // ← 選択肢②
          return const LoadingIndicator();
        }
