@deepak-saralaya I'm having the same issue and reading the issue #181 looks like is because I'm trying execute on NativeScript Preview and barcode scanner rely on third party native libraries the are not bundled with NativeScript Preview app.

Same issue here with the default demo https://github.com/EddyVerbruggen/nativescript-barcodescanner/tree/master/demo

@hailite Care to give me a decent reproduction path?

[hi-hai]

@EddyVerbruggen please check https://play.nativescript.org/?template=play-tsc&id=CB7XFu&v=2 thanks.

@hailite Does the Preview app ship with the barcodescanner plugin? If not this is an expected result. I see you added the JS side to your playground, but the native bits are missing. Please run on a real device and see what happens.
