What are modal bottom sheets and how do they differ from other types of sheets?
Modal bottom sheets are a type of user interface component that appears at the bottom of a screen, typically in response to a user’s action. They are designed to provide additional information, options, or functionality without taking up the entire screen. Unlike other types of sheets, such as full-screen sheets or popovers, modal bottom sheets are anchored to the bottom of the screen and can be easily dismissed by the user. This makes them a convenient and non-intrusive way to present secondary content or actions.
The key difference between modal bottom sheets and other types of sheets is their presentation style and behavior. Modal bottom sheets are typically presented in a modal fashion, meaning they appear on top of the underlying content and must be dismissed before the user can interact with the rest of the screen. This makes them well-suited for presenting critical information or requiring user input, as they cannot be ignored. In contrast, other types of sheets may be presented in a non-modal fashion, allowing the user to interact with the underlying content while the sheet is still visible.
