startConnect 静态方法

Future<ConnectionTask<Socket>> startConnect(
  1. dynamic host,
  2. int port, {
  3. dynamic sourceAddress,
  4. int sourcePort = 0,
})

与 connect 类似，但返回一个 Future，该 Future 在不再需要 Socket 时可以被取消。

实现

static Future<ConnectionTask<Socket>> startConnect(host, int port,
    {sourceAddress, int sourcePort = 0}) {
  final IOOverrides? overrides = IOOverrides.current;
  if (overrides == null) {
    return Socket._startConnect(host, port,
        sourceAddress: sourceAddress, sourcePort: sourcePort);
  }
  return overrides.socketStartConnect(host, port,
      sourceAddress: sourceAddress, sourcePort: sourcePort);
}
