## 販売アシスト1号の機能
販売アシスト1号は、営業マンの販売業務を支援するためのアプリケーションです。主な機能は以下の通りです。
- ファイル名の規則 "{date}({請求等}){顧客名}_{件名}_{金額カンマ付}円_{sha256}" 20251202(請求)佐々木製作所_あの件_20,000円_25ab85cc9988
- 伝票(件名)の管理
- 管理ではファイルの様にオブジェクトとして管理します。
- 顧客マスター管理
- 商品マスター管理
- 見積納品請求領収証の作成
- 見積納品請求領収証の一覧表示
- 見積納品請求領収証のPDF出力
- PDFの管理
- GPSと顧客マスターを連携し座標の履歴を記録する機能
- フォーム入力時にGPS情報で自動的に顧客マスターから候補を選出する機能
- 入力時にQRコードやOCRをGoogleレンズを使ってアシストします
- レシート印刷するポータブルプリンタを使って領収証印刷する機能
- 印刷時にQRコードを印刷する機能
- Googleドライブにバックアップする機能
- 未来の機能(今は実装しない可能にしておく)：odooとの同期・連携 伝票単位で同期
アプリの基本言語は日本語です。コメントも日本語と英語併記です。可読性は重視しません。AIの開発効率を最大に上げるものです。
表示言語は日本語です。環境により英語を表示する機能は未来に実装予定です。
見積・納品・請求・領収証はフォームがほぼ同じですが、項目が時間と共に変化するので件名が同じでも明細は異なる場合があります。
伝票はsqliteで管理します。

「明細の編集機能」に「値引き」と「項目削除」の機能を追加しました！
これにより、単なる数量・単価の入力だけでなく、以下のような実務に即した操作が可能になります。
### 今回のアップデート内容
1. **値引き項目への対応**:
* 各明細の「数量」や「単価」を調整し、その項目が値引きの場合は、すぐ右にある **「値引」チェックボックス** をオンにします。
* 詳細画面の編集モードで、各明細の「数量」や「単価」の入力欄に加えて、その項目が「値引き」かどうかの **チェックボックス** が表示されます。
* 「値引き」にチェックを入れると、その項目の小計（金額）がマイナス表示になり、自動的に合計金額にも反映されます。
2. **明細項目の削除**:
* 各明細行の右端に **「ゴミ箱」アイコン** を追加しました。
* これをタップすると、その明細行をリストから削除できます。
3. **PDF生成への反映**:
* `pdf_generator.dart` のPDF生成ロジックで、値引き項目はマイナス表示されるように調整しました。
4. **UIの微調整**:
* 「合計金額」の表示に「¥」マークがつくようにしました。
* 「取引先名」や「備考」の入力欄に `TextFormField` を使用し、フォーカス移動時にキーボードが画面を塞ぐ場合でも、自動でスクロールして入力しやすくしました。（「ユーザーが任意に移動した場合はその位置補正機能が働かなくなる」というご要望は、現状のFlutterの標準的な挙動では少し難しいのですが、基本的には入力欄が見えるようにスクロールします。）
* 「マスターから選択」ボタンの横に、「空の行を追加」ボタンも追加しました。
### 使い方のポイント
* **値引きの入力**:
1. 詳細画面で「編集」モードに入ります。
* 明細の「数量」や「単価」を調整し、その項目が値引きの場合は、すぐ右にある **「値引」チェックボックス** をオンにします。
3. 行の「金額」と、画面下部の「合計」が自動でマイナス表示・再計算されます。
* **明細の削除**:
1. 編集モードで、削除したい行の右端にある「ゴミ箱」アイコンをタップします。
* 確認ダイアログが表示されるので、「OK」を押すと行が削除されます。
これで、実務でよくある「値引き」や「項目削除」といった操作も、アプリ内で完結できるようになりました。
ぜひ、色々と試してみてください！
