海外TECH	DEV Community	Creating a High-Performing Barcode/QR Code Scanner in Flutter — Tips, Tricks and Advanced Feature	https://dev.to/siddhardha/creating-a-high-performing-barcodeqr-code-scanner-in-flutter-tips-tricks-and-advanced-feature-3k77	Creating a High Performing Barcode QR Code Scanner in Flutter ーTips Tricks and Advanced FeatureIn today s digital age barcode and QR code scanning have become essential features in many mobile applications Whether for product scanning in retail apps or ticket scanning in event management apps the ability to scan and decode barcodes and QR codes can add a lot of value to an app As a mobile developer I have always been fascinated by the endless possibilities that barcode and QR code scanning can bring to mobile applications The ability to scan products in retail apps check in to events and access information with a simple scan is not just a convenience but a necessity And as I embark on creating my very own barcode QR code scanner using Flutter s camera package I can t help but feel a sense of excitement and anticipation In this article I will take you on a journey through the process of creating a scanner that is not only functional but also visually stunning From setting up the project to adding advanced features and functionalities we ll explore every aspect of creating a dynamic and user friendly scanner We will delve into the depths of the camera package and unleash its full potential to create a scanner that stands out from the rest Setting up the projectThe first step in creating our scanner is to set up a new Flutter project Once the project is set up we need to install the camera package To do this add the following line of code to the pubspec yaml file camera The camera package provides a CameraController class which we will use to control the camera We need to import the necessary libraries and classes At the top of your main dart file add the following imports import package camera camera dart import package flutter material dart Creating the camera previewNext we will build the camera preview widget This widget will display the camera s live feed on the screen and allow us to take a picture To do this we will use the CameraPreview widget provided by the camera package CameraPreview controller It takes a CameraController object as a parameter which we need to initialize with the desired camera final cameras await availableCameras final firstCamera cameras first controller CameraController firstCamera ResolutionPreset medium await controller initialize In the above code we are using the availableCameras method provided by the camera package to get a list of all the available cameras on the device Then we are initializing CameraController the first camera in the list and set the resolution to medium using ResolutionPreset medium Scanning the codeNow that we have the camera preview on the screen we can add the barcode QR code scanning functionality The camera package provides a BarcodeScanner the class that can be used for this purpose var result await BarcodeScanner scan This will return a ScanResultobject containing the scanned data To display the scanned data on the screen we can use a Text widget Text result rawContent You can also add options to switch between barcode and QR code scanning using BarcodeScanner scan onlyFormat BarcodeFormat qr Enhancing the user experienceTo enhance the user experience we can add a flash toggle button zoom feature and focus feature The flash toggle button can be implemented using the controller toggleFlash method The zoom feature can be implemented using the controller zoom value method where the value is double between and The focus feature can be implemented using the controller setFocus point method where a point is a Offset object representing the point on the screen where the focus should be setAdditionally You can also add a function to save the scanned data to a database or cloud storage for future reference This way users can access the scanned data at a later time You can use popular databases like Firebase or cloud storage services like AWS S to store the data Furthermore another feature that can be added is the ability for the user to select the desired camera front or back This can be done by providing options for the user to select the camera and then initializing the CameraController with the selected camera To learn more about implementing the camera package in Flutter you can refer to the camera package documentation and the Flutter camera app tutorial To learn more about using Firebase and AWS S to store data you can refer to the Firebase documentation and the AWS S documentation Another feature that you may want to consider is the ability to scan multiple codes at once You can achieve this by using a loop or a recursive function that repeatedly calls the BarcodeScanner scan method until the user decides to stop scanning or a certain number of scans is reached You can also include an option to scan codes in the background allowing the user to continue using the app while the scanner is running This can be achieved by using a background service or a plugin like the flutter background geolocation to run the scanner in the background To improve the performance of the scanner you can also consider using a faster scanning library like zxing which is a popular open source barcode scanning library for Java and Android It can be used in Flutter by creating a wrapper around it using a plugin like flutter barcode scannerFinally you may want to consider implementing a feature to scan barcodes or QR codes from an image file which allows the user to scan codes from an existing image file or screenshot This can be achieved by using a library like pyzbar which can be used to extract the barcode or QR code data from an image file Additionally you may also want to consider adding a user interface element such as a button or a gesture detector to trigger the barcode QR code scanning functionality This will provide a more intuitive and user friendly experience for your users Also you might want to consider adding a loading indicator or a message to inform the user that the scanning is in progress so the user knows what s happening and can have a better understanding of the app s functionality In addition you may want to consider error handling in case the scanning process fails For example you can display an error message or a dialogue box to inform the user that the scanning failed and ask the user to try again Finally it s also a good idea to test your barcode QR code scanner on different devices and platforms to ensure that it works correctly and provides a seamless experience for your users Overall creating a barcode QR code scanner in Flutter using the camera package is a relatively straightforward process but by adding some additional features and functionalities you can provide an even better user experience and make your app stand out Thank you for taking the time to read this blog I hope you found the information provided to be helpful and

海外TECH	DEV Community	WanderXP — Organize your travel with ease	https://dev.to/sbis04/wanderxp-organize-your-travel-with-ease-205d	WanderXP ーOrganize your travel with ease OverviewIt s always a hassle to manage all the necessities while deciding a travel plan What if you could keep everything organized inside a single app WanderXP helps you to keep your travel requirements organized including flight and hotel details and the notable places that you don t want to miss visiting Category Submission Integration Innovators App LinkThe app is designed for mobile platforms small form factor but as Flutter is used for building so it s a cross platform app capable of running on Android iOS Windows Linux and Web Web app link Please scale the window to mobile form factor while running on web Mobile app link Android Please try this for better experience as it s optimized for mobile platforms You can also follow the steps on the GitHub project page if you want to try out the app on other platforms Project DescriptionThe primary features of the app are as follows Store multiple trip information travel start amp end dates flight info hotel info places to visit during the trip Upload documents in a organized manner like flight and hotel booking documents Secure user management with a robust authentication system Discover new suggestions for popular places to travel ArchitectureHere s an overview of the entire architecture of the cross platform application along with the backend infrastructure built with Flask and managed on Linode The tech stack used for building this project FlutterFlow It s a no code platform that I have used for designing the app from scratch connecting with the REST API and then generating the source code in Flutter Flask Used for building the REST API to manage user authentication database CRUD operations and storing files Linode For getting access to the cloud computing infrastructure along with their managed database SQL and object storage Frontend appThe Flutter application consists of the following screens pages SplashScreenHomePageLoginPageSignUpPageDiscoverPageTripViewPageCreateTripPageFlightInfoPageHotelReservationPagePlacesToVisitPageTripPageEditProfile Backend REST APIThe REST API built with Flask mainly consists of the following endpoints register To create account for a new user login To log in an already registered user places Fetching all the top places to discover place To retrieve a single place

ScreenshotsLicenseCopyright c Souvik BiswasPermission… View on GitHub Permissive LicenseThe project is licensed under the MIT License BackgroundTo most people the problem with travel management might not seem that hard to solve But upon searching we found that there s very limited applications available on the market that provides a minimalist UI and also gets the job done The second reason behind building a travel management app was that I wanted to learn how to use Linode and this seemed to me a very good usecase of Managed Database and Object Storage services provided by Linode How I built itI have mainly used three services provided by Linode Shared CPU I used a Ubuntu shared compute instance Managed Database with MySQL v For storing user data location information and the trips planned by each user I have also designed a robust email password authentication system Object storage For storing the trip documents like flight bookings and hotel reservation files This was my first time using Linode for managing the backend of a mobile application And the entire integration process was pretty smooth for me some of the documentation pages helped a lot This hackathon helped me to learn how to build a end to end product consisting of a frontend backend and cloud server Thanks to Linode amp DEV team for organzing this hackathon One suggestion of improvement It would have been a lot faster while working with the Managed Database if there was a SQL viewer editor inside the Linode Cloud Console I spent a lot of time authenticating into the database locally and then running the SQL command to view the table data every time while testing the queries from the mobile app Additional Resources InfoSome resources that helped while working on this project are as follows	2023-02-20
