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-community/ui-barcodeview" on the Page element

XML

<Page xmlns:bc="@nativescript-community/ui-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-community/ui-barcodeview';
registerElement('BarcodeView', () => BarcodeView);

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

NativeScript + Vue

(<any>Vue).registerElement('BarcodeView', () => require('@nativescript-community/ui-barcodeview').BarcodeView);
