I want to use this extension in my plugin: https://plugins.jetbrains.com/docs/intellij/extension-point-list.html#designerxml
The first one in the link: com.android.tools.idea.uibuilder.editor.multirepresentation.sourcecode.sourceCodePreviewRepresentationProvider is the one I want to use. I want to create a PreviewRepresentation using this extension point. However I don't know how to do this and I could not find any examples on how to implement this. So I would like to know how to implement this.
