创建List : var list = [1,2,3,"Dart",true];
创建不可变List : var list = const [1,2,3,"Dart",true];
构造创建：var list3 = new List();
常用操作：
[],length,add(),insert(),remove(),clear()indexOf(),lastIndexOf()
排序sort(),子数组 sublist()
打乱shuffle(),转为Map: asMap(),遍历forEach()
//创建list var list1 = [1,2,3,"Dart",true]; print(list1); //下标索引打印对于元素 print(list1[2]); list1[1] = "Hello"; print(list1); //创建不可变元素 var list2 = const [1,2,3]; // list2[0] = 5; The value of the local variable 'list2' isn't used. //构造方法创建 var list3 = new List(); print(list3); var list = ["hello","dart"]; print(list.length); list.add("New"); print(list); //插入在index为1的位置 list.insert(1, "Java"); print(list); //移除元素 list.remove("Java"); print(list); //元素对应的位置 print(list.indexOf("dart1")); //排序 list.sort(); print(list); //截取从1开始 print(list.sublist(1)); list.forEach(print); list.clear(); print(list);
