onConnectivityChanged property

Stream<NetworkConnectionInfo> get onConnectivityChanged

监听网络连接变化 / Emits a fresh snapshot whenever connectivity changes.

立即发出一次当前状态，随后在每次底层变化时重新采集 / Emits the current state immediately, then re-samples on every change.

Implementation

Stream<NetworkConnectionInfo> get onConnectivityChanged async* {
  yield await checkConnection();
  await for (final _ in _adapter.onConnectivityChanged) {
    yield await checkConnection();
  }
}
