2个权限请求接连出现？

Question

我的代码应该一个接一个地请求两个权限，但有些代码如何一个接一个地显示 2 个权限请求。

我该怎么做才能解决这个问题？

Future<void> checkContactPermission() async {
  var status = await Permission.contacts.status;
  if (!status.isGranted) {
    PermissionStatus permissionStatus = await Permission.contacts.request();
    if (status.isDenied) {
      PermissionStatus permissionStatus = await Permission.contacts.request();
    }
  }
  if (status.isGranted) {
    var contacts = await ContactsService.getContacts(withThumbnails: false);
    var list = contacts;
    list.shuffle();
    var FamilyMember = (list.first.phones?.first.value);
    await FlutterPhoneDirectCaller.callNumber('$FamilyMember');
  }
}

您正在检查过期状态

if (status.isDenied) {
  PermissionStatus permissionStatus = await Permission.contacts.request();
}

刷新状态再使用检查

Future<void> checkContactPermission() async {
  var status = await Permission.contacts.status;
  if (!status.isGranted) {
    PermissionStatus permissionStatus = await Permission.contacts.request();
    status = await Permission.contacts.status;
    if (status.isDenied) {
      PermissionStatus permissionStatus = await Permission.contacts.request();
    }
  }
  if (status.isGranted) {
    var contacts = await ContactsService.getContacts(withThumbnails: false);
    var list = contacts;
    list.shuffle();
    var FamilyMember = (list.first.phones?.first.value);
    await FlutterPhoneDirectCaller.callNumber('$FamilyMember');
  }
}

或使用来自

的结果状态

PermissionStatus permissionStatus = await Permission.contacts.request();
