# blue_thermal_printer
[](https://pub.dev/packages/blue_thermal_printer)
[](https://twitter.com/kakzaki_id)
A new Flutter plugin for connecting to thermal printer via bluetooth
(Android Only),
this plugin is still under development
Note: Migrate your project to AndroidX
## Platform Support
| Android | iOS | MacOS | Web | Linux | Windows |
| :-----: | :-: | :---: | :-: | :---: | :-----: |
| ✔️ | ️X | ️X | ️X | ️X | ️X |
## Getting Started
1. 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. Thank you for your support!

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

# To add assets to your application, add an assets section, like this:
assets:
- assets/images/yourlogo.png
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
