Android 6.0 及以上版本要求部分重要权限必须申请动态权限，不能只通过 AndroidMainfest.xml 文件申请静态权限。请自行在 pub 上寻找第三方 Flutter 插件来实现动态权限，或者参考如下示例代码。

Java    final permissions = [Permission.camera, Permission.microphone];
    if (Platform.isAndroid) {
      permissions.add(Permission.storage);
    }
    List<Permission> missed = [];
    for (var permission in permissions) {
      PermissionStatus status = await permission.status;
      if (status != PermissionStatus.granted) {
        missed.add(permission);
      }
    }

    bool allGranted = missed.isEmpty;
    if (!allGranted) {
      List<Permission> showRationale = [];
      for (var permission in missed) {
        bool isShown = await permission.shouldShowRequestRationale;
        if (isShown) {
          showRationale.add(permission);
        }
      }

    if (showRationale.isNotEmpty) {
        ConfirmAction? action = await showDialog<ConfirmAction>(
            context: context,
            builder: (BuildContext context) {
              return AlertDialog(
                content: const Text('You need to allow some permissions'),
                actions: <Widget>[
                  TextButton(
                    child: const Text('Cancel'),
                    onPressed: () {
                      Navigator.of(context).pop(ConfirmAction.CANCEL);
                    },
                  ),
                  TextButton(
                    child: const Text('Accept'),
                    onPressed: () {
                      Navigator.of(context).pop(ConfirmAction.ACCEPT);
                    },
                  )
                ],
              );
            });
        if (action == ConfirmAction.ACCEPT) {
          Map<Permission, PermissionStatus> allStatus = await missed.request();
          allGranted = true;
          for (var status in allStatus.values) {
            if (status != PermissionStatus.granted) {
              allGranted = false;
            }
          }
        }
      } else {
        Map<Permission, PermissionStatus> allStatus = await missed.request();
        allGranted = true;
        for (var status in allStatus.values) {
          if (status != PermissionStatus.granted) {
            allGranted = false;
          }
        }
      }
    }

如果使用 Platform View，并且 Flutter 版本低于 1.22，请在 Info > Custom iOS Target Properties 中，增加字段 io.flutter.embedded_views_preview，并设置 Value 为 YES。
