状況
2ヶ月くらい放置のアプリを久しぶりに更新しようとしたら、「The method ‘File.create’ has fewer named arguments than those of overridden method ‘File.create’.」というエラーが発生して、起動できなかった。
その間にFlutterのバージョンが「 3.7.1」に上がっている。
解決方法
以下を実施して、dependenciesにfileを追加して実行したら、動作するようになった。
実施後、fileを消しても動作する。
flutter pub add file
flutter pub get考察
fileのパッケージだけ更新されてなかったけど、dependenciesにfileを追加したことで、強制的に更新できたのかな。
参考
- flutter The method ‘File.create’ has fewer named arguments than those of overridden method ‘File.create’
上記の解決方法と、Dart の更新でもいけると記載がある。(私はfileを追加したら解決しました)
