USER # スマートフォン用 見積納品請求領収書発行システム を制作します
|
||
USER - flutterを使います
|
||
USER - 今は初期段階なので請求書だけを作ります
|
||
USER - 今は初期段階なのでスタンドアロンですが将来的にデータをodooとOnline時に同期する予定です
|
||
USER - 今はデータをローカルのsqliteで管理します
|
||
USER - 顧客データはスマートフォンの住所録から取り込むか貼り付けか手入力します
|
||
USER - 商品データは手入力しsqliteで管理します
|
||
USER - 値引きも商品データとしてsqliteで管理します

SYSTEM Output a copy of each file that needs changes.
|

SYSTEM
|

SYSTEM - First line: the filename with any originally provided path; no extra markup, punctuation, comments, etc. **JUST** the filename with path.
|

||
USER
|
||
USER path/to/filename.js
|
||
USER ```
|
||
USER // entire file content ...
|
||
USER // ... goes in between
|

USER ```
|
||
USER

|
||
USER - First line: the filename with any originally provided path; no extra markup, punctuation, comments, etc. **JUST** the filename with path.
|
||
USER - Second line: opening ```
|
||
USER - ... entire content of the file ...
|

USER To suggest changes to a file you MUST return a *file listing* that contains the entire content of the file.
|
||
USER *NEVER* skip, omit or elide content from a *file listing* using "..." or by adding comments like "... rest of code..."!
|
||
USER Create a new file you MUST return a *file listing* which includes an appropriate filename, including any appropriate path.

|
||
USER - Flutter SDK 3.x インストール
|
||
USER - `pubspec.yaml` に必要パッケージ追加
|
||
USER 2. **データベース設計**
|
||
USER - `db_helper.dart` でテーブル作成・CRUD実装
|
||
USER 3. **モデルクラス**
|
||
USER - `Customer`, `Product`, `Invoice`, `InvoiceItem` を作成
|
||
USER 4. **状態管理**
|
||
USER - `CustomerProvider`, `ProductProvider`, `InvoiceProvider` を実装

||
USER - `Customer`, `Product`, `Invoice`, `InvoiceItem` を作成
|
||
USER 4. **状態管理**
|
||
USER - `CustomerProvider`, `ProductProvider`, `InvoiceProvider` を実装

USER To suggest changes to a file you MUST return the entire content of the updated file.
|
||
USER You MUST use this *file listing* format:
|
||
USER
|
||
USER path/to/filename.js
|
||
USER ```
|
||
USER // entire file content ...
|
||
USER // ... goes in between
|
||
USER ```
|
||
USER
|
||
USER Every *file listing* MUST use this format:
|
||
USER - First line: the filename with any originally provided path; no extra markup, punctuation, comments, etc. **JUST** the filename with path.
|
||
USER - Second line: opening ```
|
||
USER - ... entire content of the file ...
|
||
USER - Final line: closing ```
|
||
USER
|
||
USER To suggest changes to a file you MUST return a *file listing* that contains the entire content of the file.
|
||
USER *NEVER* skip, omit or elide content from a *file listing* using "..." or by adding comments like "... rest of code..."!
|
||
USER Create a new file you MUST return a *file listing* which includes an appropriate filename, including any appropriate path.

ASSISTANT To suggest changes to a file you MUST return the entire content of the updated file.
|
||
ASSISTANT You MUST use this *file listing* format:
|
||
ASSISTANT
|
||
ASSISTANT path/to/filename.js
|
||
ASSISTANT ```
|
||
ASSISTANT // entire file content ...
|
||
ASSISTANT // ... goes in between
|
||
ASSISTANT ```
|
||
ASSISTANT
|
||
ASSISTANT Every *file listing* MUST use this format:
|
||
ASSISTANT - First line: the filename with any originally provided path; no extra markup, punctuation, comments, etc. **JUST** the filename with path.
|
||
ASSISTANT - Second line: opening ```
|
||
ASSISTANT - ... entire content of the file ...
|
||
ASSISTANT - Final line: closing ```
|
||
ASSISTANT
|
||
ASSISTANT To suggest changes to a file you MUST return a *file listing* that contains the entire content of the file.
|
||
ASSISTANT *NEVER* skip, omit or elide content from a *file listing* using "..." or by adding comments like "... rest of code..."!
|
||
ASSISTANT Create a new file you MUST return a *file listing* which includes an appropriate filename, including any appropriate path.
