StageXL_DragonBones #

The DragonBones runtime for the StageXL library.

DragonBones is an open source 2D skeleton animation solution very popular among Flash and Starling developers. The editor is available for Mac and Windows and does not require Adobe Flash Pro. Find more information here:

NOTE: as of version 0.3.0-dev, StageXL_DragonBones requires a Dart 2 SDK.



This runtime started as a direct port of the original AS3 runtime for DragonBones. Unfortunately the original runtime is quite complex and difficult to read. Therefore we decided to implement the DragonBones runtime for StageXL from scratch. This should make it easier to maintain the runtime, fix bugs and add new features. The drawback is that we don't support all the features of the original runtime yet. Please open new issues with your favorite runtime feature we should add next.

Maintenance suggestions

The package description is too short. (-12 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Homepage URL is insecure. (-5 points)

Update the homepage field and use a secure (https) URL.

Maintain an example.

None of the files in the package's example/ directory matches known example patterns.

Common filename patterns include main.dart, example.dart, and stagexl_dragonbones.dart. Packages with multiple examples should provide example/
