Get Events with the Flow CLI

Use the event command to fetch a single or multiple events in a specific range of blocks. You can provide start and end block height range, but also specify number of the latest blocks to be used to search for specified event. Events are fetched concurrently by using multiple workers which optionally you can also control by specifying the flags.
