Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toJson(
) → Map< String, dynamic> - 转换为基本数据类型的Map。转换结果可以直接使用jsonEncode进行序列化,可以直接保存到mongo数据库
-
toKValues(
) → Map< String, dynamic> - 转换为用字符串key读取字段值的Map
-
toString(
) → String - jsonEncode(this)抛出的异常被吃掉了,所以需要写成jsonEncode(toJson())
-
updateByJson(
Map< String, dynamic> map, {Location? parser}) → void -
通过基本数据类型的Map来更新字段。来源
map
可以直接使用jsonEncode进行序列化,可以直接保存到mongo数据库 -
updateByKValues(
Map< String, dynamic> map) → void - 通过用字符串key读取字段值的Map来更新字段
Operators
-
operator ==(
Object other) → bool -
The equality operator.
