Devs deploy hashmap witchcraft to slay one specific pop-up amid dialog apocalypse

Developers using the openCustomDialog method to create custom pop-up dialogs can encounter issues when trying to close a specified dialog, particularly when multiple dialogs are open on the page. The UIContext's getPromptAction method provides the openCustomDialog and closeCustomDialog methods, which can be used to open and close custom dialogs, respectively. To correctly close a specified dialog, it is essential to properly handle dialog IDs in the dialogMap, ensuring accurate storage and retrieval. When openCustomDialog creates a pop-up window, it returns a unique dialogId in the callback, allowing developers to store the opened pop-ups and their corresponding IDs using data structures like Map. By validating the dialog ID assignment and close operation, developers can prevent errors and ensure that the correct dialog closes when the "Close pop-up window" button is clicked, as demonstrated in the provided code example using the UIContext and HashMap from the @kit.BasicServicesKit and @kit.ArkTS libraries.
