class PluginInstanceConverter in Plugin 8.2

Converts plugin IDs in route parameters to plugin instances.

This is useful in case you want to create a plugin in the URI; for example, if you use plugins as entity bundles.

To use it, add a `plugin.plugin_instance` key to the route parameter's options. Its value is as follows:

example.route:
  path: foo/{bar}
  options:
    parameters:
      bar:
        plugin.plugin_instance:
          # Whether the conversion is enabled. Boolean. Optional. Defaults
          # to TRUE.
          enabled: TRUE
          # The ID of the instance's plugin type. String. Required.
          plugin_type_id: "foo.bar"

To use the default behavior, its value is as follows:

example.route:
  path: foo/{bar}d
  options:
    parameters:
      bar:
        plugin.plugin_type:
          # The ID of the instance's plugin type. String. Required.
          plugin_type_id: "foo.bar"
