dart语言学习（五）— List列表

• List（数组）创建

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] = "huangxiaoguo";
		  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();
		  print(list);
		
		  print(list.sublist(2));
		
		  list.forEach(print);
		
		  list.clear();
		  print(list);
		}
