list methods in dart code example
Example 1: inserting elements to integer array dart
import 'dart:core';
void main() {
List<int> intArr = [1,2,3,4,5];
//adding single int to list
intArr.add(6);
//adding multiple int to list
intArr.addAll([7,8]);
//adding element or elements to specific location
//syntax: List.insert(index,value)
intArr.insert(0,0);
//syntax: List.insertAll(index, iterable_list_of _values)
intArr.insertAll(0,[-2,-1]);
}
Example 2: get single element from list in dart
var firstList = [1,2,3,4,5,6]; print(firstList.firstWhere((i) => i < 4)); // 1 var sList = ['one', 'two', 'three', 'four']; print(sList.firstWhere((i) => i.length > 3)); // three
