Depend on it Add this to your package's pubspec.yaml file: dependencies: blue_thermal_printer: ^any 2. Install it You can install packages from the command line: with Flutter: $ flutter packages get Alternatively, your editor might support flutter packages get. Check the docs for your editor to learn more. 3. Import it Now in your Dart code, you can use: import 'package:blue_thermal_printer/blue_thermal_printer.dart'; EXAMPLE: For detail demonstration please look at [example](https://github.com/kakzaki/blue_thermal_printer/tree/master/example) folder Note: make sure to upgrade your project to compileSdkVersion 31 or above If you like my content, please consider buying me a coffee.
