Dart bindings for FLTK!

Yes! FLTK in Dart, just like this:

import 'package:fltk/fltk.dart' as fl;

int main() {
  var window = new fl.Window(350, 180, 'FLTK');
  var box = new fl.Box(20, 40, 310, 100, 'Hello, World!');
  return fl.run();

  • dartgl
  • cairodart

State of the art

This library is mostly experimental and a way to spend some time. Currently only a subset of features are supported (the exiting ones like loading images, displaying OpenGL graphics, and asynchronous event streams). The majority of widgets is not yet ported to Dart. However a sophisticated code generation program is already in place and adding simple widgets is pretty easy. If this library is useful for you and you need more widgets, feel free to open an issue!


Most bindings are automatically generated from YAML descriptions of the FLTK functions and classes. Class bindings do not create the target class directly, instead they create a wrapper class that takes care of draw and callback events.


Maybe we should use static linking for the FLTK libraries so this extension can be used without locally compiling FLTK.

1. Depend on it

Add this to your package's pubspec.yaml file:

  fltk: "^0.0.5"

2. Install it

You can install packages from the command line:

with pub:

$ pub get

Alternatively, your editor might support pub get. Check the docs for your editor to learn more.

3. Import it

Now in your Dart code, you can use:

import 'package:fltk/fltk.dart';

       Command: tar --version
  • Fix platform conflicts.

    Make sure none of the libraries use mutually exclusive dependendencies.

  • Maintain CHANGELOG.md.

    Changelog entries help clients to follow the progress in your code.

  • Fix issues reported by dartanalyzer.

    dartanalyzer reported 1 error(s) and 0 warning(s).

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Maintain an example.

    None of the files in your example/ directory matches a known example patterns. Common file name patterns include: main.dart, example.dart or you could also use fltk.dart.

  • Use analysis_options.yaml.

    Rename old .analysis_options file to analysis_options.yaml.
