Build your own Acanvas project now – with Acanvas Generator!

• Blazing fast IoC/DI/MVC UI framework for WebGL and Canvas2D, written in Dart.
• Write web apps, games, or both, in pure Dart. No HTML, no CSS, no JS.

Features

Acanvas Spring is a port of Spring Actionscript, an official Spring Framework implementation, to Dart 2.0 and StagelXL.

• ApplicationContext - Add any object to the project's runtime context, and by Interface injection and Interface postprocessing, wire them into Acanvas Spring or Acanvas Framework.
  • ObjectFactory - Creates and manages objects.
  • InstanceCache - So much better than singletons.
  • PropertyProvider - Load and access language or configuration properties conveniently.
• Inversion of Control
  • Interface Injection - Inject other Acanvas Spring objects into your object based on the Interfaces it implements.
  • PostProcessing - Have other Acanvas Spring objects postprocess your object based on its Interfaces, object name, or type.
• Micro MVC library - The Controller is implemented as front controller dispatching to Commands and Command Sequences via Signals.

Examples

• The Acanvas Framework Demo wouldn't be possible without Acanvas Spring.
• The best way to learn how to use Acanvas Spring and Acanvas Framework by generating a project with Acanvas Generator.

Limitations

Acanvas Spring is targeted for use in Dart 2.0 web projects, and as such is omitting all Spring functionality that would negatively affect file size, especially those requiring reflection. As such, not present in Acanvas Spring are:

• XMLApplicationContext - Additional impediment: Dart offers only basic XML libraries.
• Stageprocessing - Additional impediment: CPU resource heavy.
• Configuration with Annotations and Metadata.
• Instantiation and Injection based on class Type.
