List

 /// Lists : In Dart, arrays are List objects and elements are ordered in sequence in a LIST

/// Types of List : Fixed Length List & Growable List

/// List Collection
void main() {
  /// 1st Way to declare List
  // List lst = [10, 20, 30];  //This is the Dynamic Type Growable List
  // print(lst);

  /// 2nd Way to declare List
  // List lstn;
  // lstn = [40, 50, "Hello", 2.44];
  // print(lstn);

  /// 3rd Way to declare List
  // List lsnew = [1.1, 2.2, 3.3];
  // print(lsnew);
  // lsnew = ["std1", "std2", "std3"];
  // print(lsnew);

  /// Particularly Specifying Data Type in List
  // List<String> lst1 = ["Hello", "How", "are", "you", "?"];
  // print(lst1);

  // List<double> lst2 = [1.1, 2.89, 4, 1];
  // print(lst2);

  /// Print particular List Value
  // List prt = [1.1, 2.33, 5.21, "Hello", "Hii", 4,];
  // print(prt[1]);
  // print(prt[3]);
  // print(prt[5]);

  /// Updating List Values
  // List upd = [1.1, 2.2, 3.3];
  // upd[1] = 50;
  // upd[2] = 88;
  // print(upd);

  /// Add new element in List
  // List ltr = [1.1, 2.2, 3.3];
  // ltr.add(44);
  // ltr.add(20);
  // print(ltr);

  /// Remove element in List
  // List cha = [1.1, 2.2, 3.3, "Hello", 50];
  // cha.remove("Hello");
  // cha.remove(50);
  // print(cha);

  /// for in loop to printing all elements of List
  // List lo = [22, 40, 11, 33, 60];
  // for(int i in lo) {
  //   print(i);
  // }

  /// Another Example of printing all elements of List using for in loop
  // List exam = [2.2, 5.90, 1.44, 8.7];
  // for(double x in exam) {
  //   print(x);
  // }

  /// Constant List
  //Here,list is constant so addition, updation, deletion...are Unsupported operation OR unmodifiable
  // List num = const [2, 44, 3.99, 5.88, 1.33, 7];
  //   //num.add(99);  //Not supported OR unmodifiable
  //   //num[0] = 33;  //Not supported OR unmodifiable
  // print(num);

  /// List Methods

  // List a = [10, 20, 30, 40, 50, 60];
  // print(a);

  // a.add(70);
  // print(a);

  // a.addAll([80, 90, 100]);
  // print(a);

  // ListName.insert(indexNumber, Value);
  // a.insert(0, 44);
  // a.insert(0, 89);
  // a.insert(4, 77);
  // a.insert(9, 100);
  // print(a);

  // print(a.first); // printing First element of the List
  // print(a.last);  // printing Last element of the List

  /// Removing element from List
  // a.remove(30); // Passing value in parameter
  // print(a);

  // a.removeAt(2);  // Passing index in parameter
  // print(a);

  // a.removeLast(); //Removing Last element in List
  // print(a);

  /// New List of elements
  // List b = [100, 56, 70, 50, 40, 22, 10, 65, 73, 43];

  // b.sort(); //  Sorting the elements of List
  // print(b);

  // b.shuffle();  // Randomly arranges the elements
  // print(b);

  //print(b.length);  //Length of the List

  //print(b.reversed);  //Reversing the List elements

  //print(b.runtimeType); //printing the Type of List (Here, above List is Dynamic)

  //print(b.isEmpty); //printing boolean whether Given List is empty OR not

  //print(b.isNotEmpty);

  // b.clear();  //Clearing the List Elements
  // print(b);

  /// Combining Two List Elements with No Repeatation of elements
      //  Creating lists
  // List a = [1, 3, 4, 5, 7];
  // List b = [5, 7, 8, 9, 10];
  //
  //     //  Combining lists
  // var c = a + b;
  //
  //     //  Printing combined list
  // print(c.toSet().toList());
