## Sufficient contrast

The `SfBarcodeGenerator` [theming](https://help.syncfusion.com/flutter/themes) support offers a consistent and standardized look, as well as the ability to customize colors for all UI elements.
The [`SfBarcodeGenerator`](https://pub.dev/documentation/syncfusion_flutter_barcodes/latest/barcodes/SfBarcodeGenerator-class.html) [theming](https://help.syncfusion.com/flutter/themes) support offers a consistent and standardized look, as well as the ability to customize colors for all UI elements.

You can customize colors for the following elements:
* [Bar color](https://help.syncfusion.com/flutter/barcode/barcode-customization)
* [Background color](https://help.syncfusion.com/flutter/barcode/barcode-customization)

## Large fonts

The `SfBarcodeGenerator` automatically adjusts font size based on device settings and scales according to the `MediaQueryData.textScaleFactor`. It also allows you to change the font size of all text elements in the barcode generator.

**Horizontal text alignment**

The horizontal text alignment can be managed with the [`textAlign`](https://pub.dev/documentation/syncfusion_flutter_barcodes/latest/barcodes/SfBarcodeGenerator/textAlign.html) property of barcode generator. Position the displayed text at the `start`, `center` or `end` of the control. The default value of [`textAlign`](https://pub.dev/documentation/syncfusion_flutter_barcodes/latest/barcodes/SfBarcodeGenerator/textAlign.html) property is center.
