 Helper function can be implement both with pure functions and by class based functions. Helper function can be access anywhere in your app, Event they are autoload as well via composer on every user request. e.g dd() data dump is an common heler function that we use while debugginh in laravel. How to implement helper functions 1 . Make a directory in app folder with  helpers name. Create a file helper.php Write dummy code in this file <? php function message ( string $string = '' ) {     return 'Hello' ; } ?> 2. Now register/set the path of this file in composer.json file add the path in autoload object like that. I define a files key and assign array to it.Array contains all helper function files path with comma separation. "autoload" : {     "psr-4" : {         "App \\ " : "app/"     },     "files" : [ "app/helpers/helper.php" ],     "classmap" : [         "database/see...

1) How to find out if a package is installed or not in Linux There are multiple ways to check find locate package is installed in linux machine or not 1.a) Using which command The  ‘which’  command returns an executable path that can be executed when the command is entered in the terminal. # which vi /usr/bin/vi 1.b) Using whereis command The  ‘whereis’  command is used to search the binary, source, and man page files for a given command. # whereis vi vi: /usr/bin/vi /usr/share/man/man1/vi.1p.gz /usr/share/man/man1/vi.1.gz 1.c) Using locate command The  ‘locate’  command performs faster than the find command because it uses an updatedb database, whereas the find command searches in real time. # locate --basename '\nano' /usr/bin/nano /usr/share/nano /usr/share/doc/nano 2) How to find out whether a package is installed or not in Linux, using package manager 2.a) On CentOS / Red Hat (RHEL) 6/7 Use  yum command  or  rpm command  to deter...

 If you have nested array mean array have another array than you can display the data in section wise. SectionList provide many features like 1) Scroll Loading. 2) Pull to refresh the list. 3) Selection separator support. 4) ScrollView effect. Example code for SectioList. import { StyleSheet , SectionList , View , Text } from "react-native" ; const SelectionListExp = () => {     const students = [         {             id : 1 ,             name : 'Adnan Zaib' ,             data : [ 'PHP' , 'Laravel' , 'JS' ]         },         {             id : 2 ,             name : 'Aiza Adnan' ,             data : [ 'PHP' , 'Laravel' , 'HTML' , 'CSS' , 'JS' ]         },         {    ...

 I this article we will discuss and cover two major points. 1) How to  use / display components in flatlist. 2) How to use props while using components in Flat list. Let say we have array of student data we can iterate over it using flat list .just the normal behaviour. But if i want to pass the single by single student data to StudentProfile component in flatlist. Here is the example code read and understand the logic.    import { FlatList , StyleSheet , Text , View } from "react-native" ;   const ComponentInFlatList = () => {     const students = [         {             id : 1 ,             name : 'Adnan' ,             email : 'exp@email.com'         },         {             id : 2 ,             name : 'Zaib' ,     ...

 To create custom list, we use map(). It loads all item at once in the list that is expensive if list contain large number of data. For small data map() function is fine. Sometimes you are asked to make list without using react-native features to check you logical mindset. so map() is js feature not react feature keep it in mind. We will use ScrollView with map() for scroll effect on our list. Example code for map() list. import { Text , View , FlatList , StyleSheet , ScrollView } from "react-native" ; const MapListExp = () => {     const students = [         {             id : 1 ,             name : 'Adnan'         },         {             id : 2 ,             name : 'Zaib'         },         {             id :...

Flat list is a react native component that is use to display large amount of data in the form of list in native app. There are many extra and advance features which flatlist provide over map() list. Flat list uses normal array as well as array of objects. Flat list take three parameters 1) data(array) 2) renderItem(loop/iteration over array) 3) define unique key (keyExtractor = { item => item.id }) Flat list features that make it more value able. 1) It load data that is only visible on screen. When the list item go off the screen it automatically delete them from the list. This way app performance grow up and give user a smooth scroll feeling. 2) It provide scrolling feature by-default.You no need to add extra component of "ScrollView" to make scroll able data list. 3) Flatlist provide these feature Header section Footer section Horizontal scrolling Separator Pull to refresh Scroll loading Scroll to a specific position in the list Multiple column support   Visit the link f...
