[![Pub Version](https://img.shields.io/pub/v/scannabletextformfield)](https://pub.dev/packages/scannabletextformfield)

A form field for text input in [Flutter Forms](https://docs.flutter.dev/cookbook/forms) that allows data to be scanned in via QR or barcodes in addition to being typed in.

## Usage Example

```dart

import 'package:scannabletextformfield/scannabletextformfield.dart';

//somewhere in your widget UI, ideally within a [Form]

ScannableTextFormField(

	validator: (value) {

		if (value == null || value.isEmpty) {

			return 'A value is required';

		}

		//add your own validation here if you want to verify the data being scanned is correct

		return null;

	},

	textInputDecoration: const InputDecoration(

		border: OutlineInputBorder(),

		labelText: "Label",

		hintText: "Placeholder hint text",

		helperText: 'additional help text',

	),

	scanTransformer: (data) => {

		//Optional: include this propperty if you want to transform the data from scanned codes before it gets entered into the text box, such as extracting an identifier from a URL.

		return data;

	}

)

```
