Functions are the building blocks of readable, maintainable, and reusable code. A function is a set of statements to perform a specific task.
🌟ForEach( ):
Iterate through entire elements in the list.
Use it when you need to scan all the elements and certain actions over individual elements.
List<String> perfumeBrand = [ "claira", "Blue wales", "Vagas" ]; perfumeBrand.forEach((brand) => print(brand)); //Output claira Blue wales Vagas 🌟Sort( ):
Sort the elements in the list.
Use it with the combination of the reversed() method to filter data in the list.
List<int> nums = [ 1-, 6, 8 ]; nums.sort( ); //Output ==> [-1, 6, 8] ************************************************************** List<String> number = [ "Four", "Six", "Two" ]; number.sort((x, y) => x.length.compareTo(y.length)); //Output ==> [Two, Four, Six] 🌟Skip( ):
Skips defined items from any List.
Use it when you need to remove any blacklisted element from an array of items (from your list).
int elementToSkip = 3; List<int> elements = [1,2,3,4,5,6,]; List<int> skippedList = elements.skip(elementToSkip).toList(); //Output ==> [1,2,4,5,6,] 🌟ToSet( ):
Removes duplicates and iterates with the same items.
Use it when don’t need users having the same email address or if you need to add unique elements.
List<int> nums = [1,1,4,5,4,]; nums.toSet( ).toList( ).sort( ); //OUTPUT ==> [1,4,5] 🌟Any( ):
Scans the elements in the list & produces boolean output depending on the provided condition.
List<String> perfumeBrand = [ "claira", "Blue wales", "Vagas" ]; perfumeBrands.any(brand) => brand.startsWith("B")); //Output ==> TRUE perfumeBrands.any(brand) => brand.startsWith("ht")); //Output ==> TRUE 🌟Shuffle( ):
Arranges elements in a random order/ sequence.
List<int> nums = [2,4,6,8,10]; nums.shuffle( ); //Output ==> [10,2,6.4.8]
