The constructor, `constructor(opt_block?: Block)`, accepts one optional parameter, `opt_block`, of type `Block`. If provided, `opt_block` represents the block linked to this event; otherwise, it's considered a blank event. This allows for tracking actions related to particular block instances.\n"]]
