### wan_android

- [ ] UI
- [ ] 路由
- [x] 网络接口请求

### 常用指令

- 手机端预览：flutter run -d chrome --web-hostname 192.168.0.107 --web-port 3002

- 设置启动端口：
```bash
flutter run -d chrome --web-port=3002
```

- 开发环境下屏蔽跨域报错: 解决 web 端，请求跨域问题
```bash
flutter run -d chrome --web-renderer canvaskit --web-browser-flag "--disable-web-security"
```

- 打包构建 apk
```bash
flutter build apk --split-per-abi
```

- 打包构建 web
```bash
flutter build web

# wasm 版本
flutter build web --wasm
```

### 通过原生方法打开蓝牙设置：

- 详解：在 flutter_blue_plus 插件中，直接打开蓝牙设置界面并不是插件本身提供的功能。不过，你可以使用平台通道（Platform Channels）来实现这一功能。如下：

- Android 中：android/app/src/main/kotlin/com/example/wan_android/MainActivity.kt

```kotlin
import android.content.Intent
import android.os.Bundle
import io.flutter.embedding.android.FlutterActivity
import io.flutter.plugin.common.MethodChannel

class MainActivity: FlutterActivity() {
    private val CHANNEL = "com.example.bluetooth/settings"

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        MethodChannel(flutterEngine?.dartExecutor?.binaryMessenger, CHANNEL).setMethodCallHandler { call, result ->
            if (call.method == "openBluetoothSettings") {
                val intent = Intent(android.provider.Settings.ACTION_BLUETOOTH_SETTINGS)
                startActivity(intent)
                result.success(null)
            } else {
                result.notImplemented()
            }
        }
    }
}

```

- IOS 中：ios/Runner/AppDelegate.swift

```swift
import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        let controller: FlutterViewController = window?.rootViewController as! FlutterViewController
        let channel = FlutterMethodChannel(name: "com.example.bluetooth/settings", binaryMessenger: controller.binaryMessenger)
        
        channel.setMethodCallHandler { (call: FlutterMethodCall, result: @escaping FlutterResult) -> Void in
            if (call.method == "openBluetoothSettings") {
                if let url = URL(string: "App-Prefs:root=Bluetooth") {
                    if UIApplication.shared.canOpenURL(url) {
                        UIApplication.shared.open(url, options: [:], completionHandler: nil)
                        result(nil)
                    } else {
                        result(FlutterError(code: "UNAVAILABLE", message: "Cannot open settings", details: nil))
                    }
                } else {
                    result(FlutterError(code: "UNAVAILABLE", message: "Cannot open settings", details: nil))
                }
            } else {
                result(FlutterMethodNotImplemented)
            }
        }

        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
}

```
