When I tried this, TS complained that the `valueChanges` function does not expect any arguments, so I took a quick look at the source and found out that the implementation is missing.\r\n\r\nI'll be providing a PR with the implementation of this shortly.\r\n\r\n","author":{"url":"https://github.com/simonxabris","@type":"Person","name":"simonxabris"},"datePublished":"2020-08-30T11:33:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/2579/angularfire/issues/2579"}
