   This bug makes it impossible to use a barcode scanner on nativescript currently as other solutions like https://market.nativescript.org/plugins/@nstudio/nativescript-barcodescanner/ are also out of date and won't function properly

   I tried using version 1.0.6 for iOS and 3.0.0 for Android, and it works perfectly. To test, you can add a script before compiling in the nativescript.config.ts file, for example:

   hooks: [
       {
         type: 'before-prepare',
         script: 'scripts-hook/mlkit-before-prepare.js',
       },
     ]
   

   script:

   module.exports = function ($logger, $platformsDataService, $projectData, hookArgs) {
     return new Promise(async (resolve, reject) => {
       const { execSync } = require('child_process')
   
       const platform = hookArgs.prepareData.platform
       const currentEnvironment = hookArgs.prepareData.env.prod || hookArgs.prepareData.env.production ? 'prod' : 'dev'
   
       $logger.info(`[MLKit Hook] before-prepare ${platform} - environment: ${currentEnvironment}`)
   
       try {
         const platformVersions = {
           android: {
             '@nativescript/mlkit-barcode-scanning': '3.0.0',
             '@nativescript/mlkit-core': '3.0.0',
           },
           ios: {
             '@nativescript/mlkit-barcode-scanning': '1.0.6',
             '@nativescript/mlkit-core': '1.0.6',
           },
         }
   
         const versions = platformVersions[platform]
         if (!versions) {
           $logger.info(`[MLKit Hook] No specific versions defined for platform: ${platform}`)
           resolve(true)
           return
         }
   
         $logger.info(`[MLKit Hook] Installing MLKit dependencies for ${platform}...`)
   
         Object.entries(versions).forEach(([packageName, version]) => {
           try {
             $logger.info(`[MLKit Hook] Installing ${packageName}@${version} for ${platform}...`)
             execSync(`npm install ${packageName}@${version} --legacy-peer-deps`, {
               cwd: $projectData.projectDir,
               stdio: 'inherit',
             })
             $logger.info(`[MLKit Hook] Successfully installed ${packageName}@${version}`)
           } catch (error) {
             $logger.error(`[MLKit Hook] Failed to install ${packageName}@${version}: ${error.message}`)
           }
         })
   
         $logger.info(`[MLKit Hook] MLKit setup completed for ${platform}`)
         resolve(true)
       } catch (error) {
         $logger.error(`[MLKit Hook] Error: ${error.message}`)
         reject(error)
       }
     })
   }
