如何在 Flutter 中获得 iOS 中的 BluetoothScan、BluetoothAdvertise 和 BluetoothConnect 权限？

Question

我已在 flutter 中使用 Permission Handler 包请求权限，但我收到的所有请求均被授予 false 请求。仅将 Permission.bluetooth.isGranted 设为 true。

await [
      Permission.bluetooth,
      Permission.bluetoothScan,
      Permission.bluetoothConnect,
      Permission.bluetoothAdvertise,
    ].request();

 bool blueScanStatus = await Permission.bluetoothScan.isGranted;
    // debugPrint(
    //     "\n==============\n | Bluetooth Scan Permissions: $blueScanStatus | \n==============\n");

    bool blueAdvStatus = await Permission.bluetoothAdvertise.isGranted;
    /* debugPrint(
        "\n==============\n | Bluetooth Advertise Permissions: $blueAdvStatus | \n==============\n");*/

    bool blueStatus = await Permission.bluetooth.isGranted;
    /* debugPrint(
        "\n==============\n | Bluetooth Permissions: $blueStatus | \n==============\n");*/

    bool blueConnectStatus = await Permission.bluetoothConnect.isGranted;

该代码在 Android 上运行良好，但仅在 iOS 上出现问题。我需要在 Info.plist 上添加一些内容吗？在此处输入图像描述

经过几次研究后这个问题已经解决，我得出的结论是ios没有BluetoothScan、BluetoohAdvertise和BluetoohConnect。 iOS 仅支持蓝牙 Permission 方法。所以我修改了下面提到的代码。

Map<Permission, PermissionStatus> blePermissions = await [
  Permission.bluetooth,
  if (Platform.isAndroid) Permission.bluetoothScan,
  if (Platform.isAndroid) Permission.bluetoothConnect,
  if (Platform.isAndroid) Permission.bluetoothAdvertise,
].request();
