true sets the camera to torch mode (always on), false turns the flashlight off.Ĭonfiguration can be applied by passing a Configuration object to the BarcodeScannerRenderer.Init() method. false turns the decoder off, the preview is still active but barcodes will not be decoded.Ĭontrols the camera flashlight if available and accessible. If true the decoder is active and tries to decode barcodes out of the image. false deactivates the preview and releases the camera. If true opens the camera and activates the preview. Holds the value of the last found barcode. Raised after the preview image gets deactivated. Raised after the preview image gets active. Raised every time when a barcode is decoded from the preview, even if the value is the same as the previews one. Raised only when the barcode text changes. the command for BarcodeChanged event would be BarcodeChangedCommand.

Ensure that only one instance at at time is active.Īll events are also available as Commands, the appropriate fields are suffixed accordingly.

Disable the camera when sleeping the device.

Disable the camera when the page gets removed from the stack.

Disable the preview when you add a page to the navigation stack.

Not doing so might lead to bad performance or unexpected camera exceptions. Thats why you should weave in camera control code into the logic of your app by utilizing the offered bindings. For example when sleeping/ resuming the device, when the page gets disposed without notifying the view or another page get pushed onto the stack. Given the complexity of apps there are a lot of combinations that prevent a reasonable automatic control of the camera. The scanning starts as soon as the element is visible on screen and stops when the view element gets removed from the stack. Since beta 0.5.0 the library only handles the most basic camera controls.

Register an EventHandler for the BarcodeScanner.BarcodeChanged event to receive the detected barcodes.įor a hands-on experience it is recommended to take a look at the sample application.

Dont forget to give it a height and width.

Create an instance of the BarcodeScanner class.

Return base.FinishedLaunching(app, options)

#ALOHA STACKS REGISTRATION#

Add the registration call BarcodeScannerRenderer.Init() to your platform specific Main class.

Set the appropriate Android permissions to allow your app to access the camera and flash if need be.

#ALOHA STACKS INSTALL#

Install the package via nuget into your PCL and platform specific projects.

Utilizing Google Play Services Vision API on Android for best possible barcode scanning performance.Lots of configuration options, bindable properties and events: Torch control, rotation support, preview freezing and other fine grained controls.Add elements on top and adapt the UI to your needs. Please note that the library currently supports Android and iOS. It provides continuous scanning, aims to give high control to the user combined with high stability. This repository is a fork of the archived Rb.Forms.Barcode, originally developed by reBuy reCommerce GmbH. Aloha.Barcodes is a Microsoft MAUI & Xamarin.Forms view for scanning barcodes.
