qrcp

Dart implementation of basic functionality of https://github.com/claudiodangelis/qrcp

Transfer files over Wi-Fi between devices by scanning a QR code without leaving the terminal.

How does it work?

qrcp binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content. When used to receive files, qrcp serves an upload page and handles the transfer.

The tool prints a QR code that encodes the text:

http://{address}:{port}/{random_path}

Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser.
