  const HistoryScreen({super.key});

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return Scaffold(
      appBar: AppBar(title: const Text('历史记录')),
      body: const Center(child: Text('历史记录页面 - 待开发')),
    );
  }
}

// screens/settings/settings_screen.dart
import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';

class SettingsScreen extends ConsumerWidget {
  const SettingsScreen({super.key});

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return Scaffold(
      appBar: AppBar(title: const Text('设置')),
      body: const Center(child: Text('设置页面 - 待开发')),
    );
  }
}

// screens/bluetooth/bluetooth_screen.dart
import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';

class BluetoothScreen extends ConsumerWidget {
  const BluetoothScreen({super.key});

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return Scaffold(
      appBar: AppBar(title: const Text('蓝牙连接')),
      body: const Center(child: Text('蓝牙连接页面 - 待开发')),
    );
  }
}

5. Android 权限配置

android/app/src/main/AndroidManifest.xml 添加权限

<!-- 在 <manifest> 标签内添加 -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

<uses-feature android:name="android.hardware.camera" android:required="true" />
<uses-feature android:name="android.hardware.bluetooth_le" android:required="true" />

android/app/build.gradle 修改最低 SDK

android {
    defaultConfig {
        minSdkVersion 21  // 改为 21
    }
}

6. 初始化项目命令

# 1. 创建项目
cd C:\Users\xdedmi\Desktop\aisee
flutter create --org com.aisee --project-name aisee_app --platforms android,ios aisee_app
cd aisee_app

# 2. 获取依赖
flutter pub get

# 3. 运行代码生成（freezed、json_serializable）
dart run build_runner build --delete-conflicting-outputs

# 4. 运行项目
flutter run

# 5. 运行测试
flutter test

7. Git 初始化

cd C:\Users\xdedmi\Desktop\aisee\aisee_app

git init
git add .
git commit -m "feat: 初始化 AISee Flutter 项目"

8. 开发顺序建议

第 1 周：项目搭建 + 首页 UI
第 2 周：相机模块 + 拍照功能
第 3 周：API 对接 + 图像上传
第 4 周：AI 分析结果展示
第 5 周：蓝牙通信模块
第 6 周：语音播报 + 历史记录
第 7 周：设置页面 + 优化
第 8 周：测试 + Bug 修复

提示：先运行 flutter pub get 安装依赖，然后按照目录结构创建文件，逐步填充代码。
