| # plugin |
| |
| Support for building plugins in Dart. |
| |
| This project defines a simple framework for defining plugins. A _plugin_ is the |
| unit of extensibility for a host application. |
| |
| An _extension point_ represents one way of extending the host application. For |
| example, a file viewer application might define an extension point to allow |
| viewers for new file types to be added to the application. |
| |
| The host application must provide at least one extension point that plugins can |
| extend. Every extension point must have a unique name associated with it, and |
| should specify the type of the objects that will be accepted as extensions. In |
| the example above, the extension point might require that all extensions |
| implement the interface FileViewer. |
| |
| Any plugin can define extension points that other plugins can extend. The host |
| application contributes its own extension point(s) by defining a plugin. |
| |
| An _extension_ is an object that a plugin associates with a particular extension |
| point. To continue the example, a plugin that supports the viewing of .gif files |
| would create an instance of GifFileViewer, a class that implements FileViewer. |
| |
| The framework in this package then connects the defined extensions with the |
| defined extension points so that the separately contributed plugins can |
| coordinate to accomplish the larger goal. |
