start method

Future<void> start(
  1. String address, {
  2. ValueChanged<String>? sourceData,
})

开始检测网络url

address 合法的url

例子：http://baidu.com

sourceData 源数据，是个json字符串

Implementation

Future<void> start(String address, {ValueChanged<String>? sourceData}) async {
  var params = <dynamic, dynamic>{};
  params['address'] = address;
  _streamSubscription = _createListingStream().listen((event) {
    sourceData?.call(event);
  }, onDone: closeListingStream);
  await _channel.invokeMethod('startTesting', params);
}
