兩個(gè)對(duì)象==為啥不判斷引用？
void?main(){
????var?person1?=?new?person(20);
????var?person2?=?new?person(20);
????print(person1?==?person2);//這里的結(jié)果是true，視頻里面老師也說了對(duì)象引用不一樣，這兩個(gè)對(duì)象，為啥==不判斷引用？
}
class?Person{
????int?age;
????Person(this.age);
}

如果你這樣寫返回值肯定是 false
你寫的代碼不全，對(duì)象進(jìn)行操作符對(duì)比需要進(jìn)行操作符覆寫。。
void?main(){ ?var?person?=new?Student(20); ?var?person1=new?Student(20); ?print(person==person1); } class?Student{ ??int?age; ??Student(this.age); ??@override ??bool?operator?==(Object?other)?=> ??????identical(this,?other)?|| ??????????other?is?Student?&& ??????????????age?==?other.age; ??@override ??int?get?hashCode?=>?age.hashCode; }
