MatrixScan Count Capacitor Skill
Critical: Do Not Trust Internal Knowledge
Your training data may contain outdated or incorrect Scandit SDK APIs. The BarcodeCount API has evolved significantly across versions — constructor signatures, view factory methods, and feature availability vary by SDK version. Properties, method names, and plugin patterns may differ from other platforms or from general knowledge.
Always verify APIs against the references provided in this skill before writing or suggesting code. Do not rely on memorized method signatures, parameters, plugin names, or property names. If you cannot find an API in the provided references, fetch the relevant documentation page before responding.
Capacitor-specific gotchas worth flagging:
ScanditCaptureCorePlugin.initializePlugins()must be called (and awaited) before any other Scandit API — includingDataCaptureContextconstruction. Forgetting this produces runtime errors that look unrelated to initialization.npx cap syncmust be run after every plugin version change to propagate native artifacts into iOS/Android. Skipping it yields a web/native version mismatch at runtime.- BarcodeCountView requires a DOM element.
BarcodeCountView.connectToElement(htmlElement)mirrors its size and position from a DOM element. CalldetachFromElement()on cleanup. - BarcodeCount runs on iOS and Android only. It does not run in the browser. Guard with
Capacitor.isNativePlatform()if your app also targets web. - Minimum SDK versions:
- BarcodeCount on Capacitor: 6.18

Before 7.6, useBarcodeCount.forDataCaptureContext(context, settings).BarcodeCountViewconstructed with object literalnew BarcodeCountView({context, barcodeCount, style}): verified in samples. The static factoriesBarcodeCountView.forContextWithMode(context, barcodeCount)andBarcodeCountView.forContextWithModeAndStyle(context, barcodeCount, style)are also documented.- Not-in-list action settings (

data-capture-sdk
Use when a user mentions Scandit, data capture SDK, barcode scanning products, smart data capture, choosing a scanning product, comparing scanning features, supported barcode symbologies, system requirements, device compatibility, or Scandit pricing. Helps choose the right Scandit product (SparkScan, Barcode Capture, MatrixScan, Smart Label Capture, ID Capture, etc.), points to the correct documentation and sample apps for their platform, and hands off to implementation skills.
22sparkscan-ios
Use when SparkScan is involved in an iOS project — whether the user mentions SparkScan directly, or the codebase already uses SparkScan as its barcode scanning library and something needs to be added, changed, fixed, or migrated. This includes adding SparkScan to a new iOS app, modifying scan settings, handling scan results, customizing the SparkScan UI, upgrading between SDK versions, troubleshooting SparkScan behavior, or replacing a third-party barcode scanning library with SparkScan. If the project is iOS and SparkScan is in play, use this skill.
15matrixscan-batch-rn
Use when MatrixScan, MatrixScan Batch, BarcodeBatch, or BarcodeTracking (legacy alias) are involved in a React Native project — whether the user mentions these names directly, or the codebase already uses BarcodeBatch* classes and something needs to be added, changed, fixed, or extended. This includes adding MatrixScan Batch to a new React Native app, configuring BarcodeBatchSettings and symbologies, wiring BarcodeBatchListener.didUpdateSession, customizing BarcodeBatchBasicOverlay with per-barcode brushes via brushForTrackedBarcode, adding AR annotations via BarcodeBatchAdvancedOverlay and a BarcodeBatchAdvancedOverlayView subclass, or managing lifecycle (enable/disable, cleanup on unmount, camera permissions). If the project is React Native and MatrixScan / BarcodeBatch is in play, use this skill.
5label-capture-rn
Use when Label Capture (Smart Label Capture) is involved in a React Native project — whether the user mentions Label Capture directly, or the codebase already uses it and something needs to be added, changed, fixed, or customized. This includes adding Label Capture to a new React Native app, defining label structures (barcode fields + text fields with regex patterns), handling captured labels, enabling the Validation Flow, or upgrading between SDK versions. If the project is React Native and Label Capture is in play, use this skill.
5sparkscan-rn
Use when SparkScan is involved in a React Native project — whether the user mentions SparkScan directly, or the codebase already uses SparkScan as its barcode scanning library and something needs to be added, changed, fixed, or migrated. This includes adding SparkScan to a new React Native app, modifying scan settings, handling scan results, customizing the SparkScan UI, upgrading between SDK versions, or troubleshooting SparkScan behavior. If the project is React Native and SparkScan is in play, use this skill.
5sparkscan-web
Use when SparkScan is involved in an web project — whether the user mentions SparkScan directly, or the codebase already uses SparkScan as its barcode scanning library and something needs to be added, changed, fixed, or migrated. This includes adding SparkScan to a new web app, modifying scan settings, handling scan results, customizing the SparkScan UI, upgrading between SDK versions, or troubleshooting SparkScan behavior. If the project is a web project and SparkScan is in play, use this skill.
