flutter端代码

Future<String> sendSMS({
  required String message,
  required List<String> recipients,
  bool sendDirect = false,
}) =>
    FlutterSmsPlatform.instance.sendSMS(
      message: message,
      recipients: recipients,
      sendDirect: sendDirect,
    );

/// Launch SMS Url Scheme on all platforms
Future<bool> launchSms({
  String? message,
  String? number,
}) =>
    FlutterSmsPlatform.instance.launchSms(number, message);

/// Launch SMS Url Scheme on all platforms
Future<bool> launchSmsMulti({
  required String message,
  required List<String> numbers,
}) =>
    FlutterSmsPlatform.instance.launchSmsMulti(numbers, message);

/// Check if you can send SMS on this platform
Future<bool> canSendSMS() => FlutterSmsPlatform.instance.canSendSMS();
