userNumberMin method

@override Future<void> userNumberMin(Map<String, dynamic> properties, [ DateTime? dateTime ])

对数值类用户属性取最小值. 如果属性还未被设置，则会赋值 0 后再进行计算.

用户属性 操作时间

Implementation

@override
Future<void> userNumberMin(
  Map<String, dynamic> properties, [
  DateTime? dateTime,
]) async {
  try {
    dynamic arguments = {'properties': properties};
    if (dateTime != null) {
      arguments = {
        'properties': properties,
        'dateTime': dateTime.microsecondsSinceEpoch,
      };
    }
    methodChannel.invokeMethod('userNumberMin',arguments);
  } on PlatformException catch (e) {
    print('userNumberMin fail: ${e.message}');
  }
}
