selfDNSTest method
A test whether the DNS record is placed or not. Uses the Google DNS JSON API to check the corresponding zone file.
Implementation
Future<bool> selfDNSTest(DnsDcvData data, {int maxAttempts = 15}) async {
for (var i = 0; i < maxAttempts; i++) {
var records = await DnsUtils.lookupRecord(
data.rRecord.name, RRecordType.TXT,
provider: DnsApiProvider.GOOGLE);
if (records!.first.data == data.rRecord.data) {
print('Found record at Google DNS');
return true;
} else {
print('Record not found yet at Google DNS');
}
await Future.delayed(Duration(seconds: 4));
}
return false;
}
