Usage

The nativescript BarcodeView is base on nativescript-barcodescanner from [Eddy Verbruggen] (https://github.com/EddyVerbruggen)

Plain NativeScript

IMPORTANT: Make sure you include xmlns:mdc="nativescript-canvas" on the Page element

XML

<Page xmlns:bc="nativescript-barcodeview">
    <StackLayout horizontalAlignment="center">
        <bc:BarcodeView width="100" height="100" scanResult="onScanResult"/>
   </StackLayout>
</Page>

NativeScript + Angular

import { registerElement } from 'nativescript-angular/element-registry';
import { BarcodeView } from 'nativescript-barcodeview';
registerElement('BarcodeView', () => BarcodeView);

<BarcodeView width="100" height="100" (scanResult)="onScanResult($event)"></CanvasView>

import Vue from 'nativescript-vue';
(<any>Vue).registerElement('BarcodeView', () => require('nativescript-barcodeview').BarcodeView);
