attach method

@override void attach(ExtensionBuilder<ExtensionDescriptor> extBuilder)

Sets up the plugin with the ContentExtensionBuilder. The plugin relies on the ContentExtensionBuilder to do its work.

Implementation

@override
void attach(ExtensionBuilder extBuilder) {
  if (extBuilder is! ContentExtensionBuilder) {
    throw ArgumentError.value(
      extBuilder,
      'extBuilder',
      'DefaultContentPlugin requires a ContentExtensionBuilder',
    );
  }

  _extensionBuilder = extBuilder;
}
