- NetworkConfig.baseUrl 改为使用 ApiEndpoints.baseUrl
- 确保构建时 --dart-define=ENV=prod 能正确切换环境

+# Flutter 构建说明
+
+## 环境配置
+
+| 环境 | ENV | API 地址 |
+|------|-----|----------|
+| 开发 | `dev` | `http://localhost:5010` |
+| 生产 | `prod` | `http://8.155.172.147:5010` |
+
+## Web 构建
+
+```bash
+# 开发环境（默认）
+flutter run -d chrome
+
+# 生产构建
+flutter build web --release --dart-define=ENV=prod
+```
+
+输出目录：`build/web/`
+
+## Android 构建
+
+```bash
+# APK (用于测试分发)
+flutter build apk --release --dart-define=ENV=prod
+
+# App Bundle (用于上架 Google Play)
+flutter build appbundle --release --dart-define=ENV=prod
+
+# 分架构构建 (减小体积)
+flutter build apk --release --dart-define=ENV=prod --split-per-abi
+```
+
+输出目录：`build/app/outputs/`
+
+## iOS 构建
+
+```bash
+# 需要 macOS
+flutter build ios --release --dart-define=ENV=prod
+```
+
+## 常用参数
+
+| 参数 | 说明 |
+|------|------|
+| `--release` | 生产模式，优化体积和性能 |
+| `--debug` | 调试模式，含完整调试信息 |
+| `--profile` | 性能分析模式 |
+| `--dart-define=ENV=prod` | 设置生产环境 |
+| `--split-per-abi` | 分架构构建 APK |
+| `--wasm` | 启用 WebAssembly (实验性) |
+
+## 代码中判断环境
+
+```dart
+import 'core/constants/api_endpoints.dart';
+
+if (ApiEndpoints.isProduction) {
+  // 生产环境逻辑
+} else {
+  // 开发环境逻辑
+}
+```
+
+## 部署 Web
+
+```bash
+# 构建后上传 build/web 目录到服务器
+scp -r build/web/* user@server:/var/www/html/
+
+# 或使用 nginx 托管
+# 将 build/web 目录配置为 nginx 静态资源目录
+```
