dart语言学习— List列表

List (数组)传教

创建List:
var  list = [1,2,3];

创建不可变的List:
var list = const[1,2,3];

构造创建: var list = new List();

常用操作： [ ],length; add(),insert();remove(),clear();indexOf(),lastIndexOf();sort(),sublist();shuffle();asMap(),forEach();

void main() {
  var list1 = [1, 2, 3, "Dart", true];
  print(list1);
  print(list1[1]);
  list1[1] = "dawangba";
  print(list1);
 //不可变的List
 var list2 = const [1,2,3];
 var list3 = new List();

//常用操作
var list  =["Hello","Dart"];
print(list[1]);
print(list.length);

list.add("New");
print(list);

list.insert(1,"aaa");
print(list);

list.remove("aaa");
print(list);

print(list.indexOf("Dart"));

list.sort();
pirnt(list);

print(list.sublist(2));

print(list.forEach());

list.clear();
print(list);
}
