On Android, cancel() called destroy() first, and destroy() sets
savedInvoke to null, so the savedInvoke?.reject("cancelled") that
follows was a no-op. The pending scan() promise was never settled and
callers awaiting it were stranded, which is especially bad in windowed
mode where the page background stays transparent.
Reject the pending invoke before tearing the camera down, matching the
order the iOS implementation already uses.
Allows your mobile application to use the camera to scan QR codes, EAN-13 and other kinds of barcodes.

Install
This plugin requires a Rust version of at least 1.64
There are three general methods of installation that we can recommend.
- Use crates.io and npm (easiest, and requires you to trust that our publishing pipeline worked)
- Pull sources directly from Github using git tags / revision hashes (most secure)
- Git submodule install this repo in your tauri project and then use file protocol to ingest the source (most secure, but inconvenient to use)
Install the Core plugin by adding the following to your Cargo.toml file:
src-tauri/Cargo.toml
[dependencies]
tauri-plugin-barcode-scanner = "2.0.0"
# alternatively with Git:
tauri-plugin-barcode-scanner = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "v2" }
You can install the JavaScript Guest bindings using your preferred JavaScript package manager:
pnpm add @tauri-apps/plugin-barcode-scanner
# or
npm add @tauri-apps/plugin-barcode-scanner
# or
yarn add @tauri-apps/plugin-barcode-scanner
Usage
First you need to register the core plugin with Tauri:
src-tauri/src/lib.rs
fn main() {
tauri::Builder::default()
.plugin(tauri_plugin_barcode_scanner::init())
.run(tauri::generate_context!())
.expect("error while running tauri application");
}
Afterwards all the plugin's APIs are available through the JavaScript guest bindings:
import { scan } from '@tauri-apps/plugin-barcode-scanner'
// `windowed: true` actually sets the webview to transparent
// instead of opening a separate view for the camera
// make sure your user interface is ready to show what is underneath with a transparent element
scan({ windowed: true, formats: [''] })
