+# gemi_invoice
+
+A new Flutter project.
+
+## Getting Started
+
+!! 日本語が主体のアプリです。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て下さい。!!
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.
+
+## 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。

+# 依頼内容
+Flutterプロジェクトのビルドエラーを解消し、顧客マスター管理（GPSソート/電話帳連携）と請求書履歴一覧の機能を完成させてください。
+
+# 現状の問題
+1. `CustomerPickerModal` 内で DB の `Customer` 型とアプリ用 `Customer` モデルが衝突し、型エラーが発生している。
+2. `pdf_list_screen.dart` で、DB から顧客情報付きの請求データを取得する `InvoiceWithCustomer` 型や `watchAllInvoices()` メソッドが見つからずエラーになっている。
+3. `invoice_input_screen.dart` で `CustomerPickerModal` を呼び出す際、古い引数 `existingCustomers` を渡しておりエラーになっている。
+
+# 実行ステップ
+1. **lib/data/database.dart の更新**:
+   - `Invoices` と `Customers` を結合して取得するための `InvoiceWithCustomer` クラスを定義してください。
+   - `AppDatabase` クラスに、最新順でデータを流す `Stream<List<InvoiceWithCustomer>> watchAllInvoices()` メソッドを実装してください。
+   - その後、`flutter pub run build_runner build --delete-conflicting-outputs` を実行してコード生成を完了させてください。
+
+2. **lib/screens/customer_picker_modal.dart の修正**:
+   - インポートで `../models/invoice_models.dart` を `app_model` として別名を付け、DBの `Customer` 型と明確に区別してください。
+   - GPS座標（latitude/longitude）を使用して、現在地に近い順にリストをソートするロジックを実装してください。
+   - 電話帳（flutter_contacts）からの取り込みと、DBへの保存（insertOnConflictUpdate）が正常に動くようにしてください。
+
+3. **lib/screens/pdf_list_screen.dart の修正**:
+   - `database.watchAllInvoices()` を使用して履歴一覧を表示するようにしてください。
+   - リストタップ時に、DBのモデルからアプリ用の `Invoice` モデルへ変換して詳細画面へ遷移させてください。
+
+4. **lib/screens/invoice_input_screen.dart の修正**:
+   - `CustomerPickerModal` の呼び出し箇所から、存在しない引数 `existingCustomers` を削除してください。
+
+# 完了条件
+`flutter build apk --debug` がエラーなく通り、かつ顧客マスターのGPSソートが機能すること。

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
