Share prototype URL from a plugin

[tank666]

Unique file identifier

Will you be publishing the plugin to the Figma Community (if not already published) or are you developing the plugin just for yourself? If the former, then you need to come up with something, such as asking the user to paste a link to a file in order to get a fileKey. If the latter, then enable the private plugin API in the manifest.json file and use the figma.fileKey.

Nothing has changed since then.

Please refer to the documentation:

fileKey: string | undefined [readonly]
The file key of the current file this plugin is running on. Only private plugins and Figma-owned resources (such as the Jira and Asana widgets) have access to this. To enable this behavior, you need to specify enablePrivatePluginApi in your manifest.json.
